Future proofing the manufacturing industry at IMTS 2014

Ensuring the industry attracts a young and

energetic workforce was a key theme of the

show. With interactive demonstrations and

projects, attendance at the IMTS Smartforce

Student Summit more than doubled

compared to 2012 and provided nearly

18,000 students, teachers and parents with

a fun insight into developments and careers

in manufacturing. “There were excited

young people everywhere, it was great to

see the enthusiasm for the industry. If these

kids are the future then we don’t have to

worry!” says Aotea Machinery’s account

manager Karl Medley.

“There was a universal vibe during the show

among exhibitors, visitors and even students,

that manufacturing is THE place to be”, said

Peter Eelman, AMT Vice President –

Exhibitions and Communications. “Even

more exciting to exhibitors was the fact that

customers came with buying intentions, and

a confidence that has not been seen in the

manufacturing industry in many years.”

Machinery giant Haas was one such

company seeing records set at the show.

“Haas had the highest lead count ever at this

year’s show and orders were taken for over

100 machines and we received over 900

enquires in just one day”, Karl Medley adds.

Eighteen of their latest machines were on

display on the 10,000m2 stand, with the

company owner Gene Haas climbing over

the equipment and talking shop with visitors

from across the globe. Their big winners

were the new UMC-750SS and ST-55

machines which will be available to the New

Zealand market in the new year - exclusively

through Aotea Machinery. The UMC-750SS

is a high speed, 40 taper, 5 axis machining

centre with 30”x20”x20” travels and

15,000rpm inline direct drive spindle, whilst

the ST-55 is long bed turning centre with a

12.5” diameter through-bore and a 55hp

vector dual-drive unit powering the spindle

through a Haas built two-speed gearbox

providing 4,250ft-lb of torque in low gear.

“If there’s one thing I took from the show

it’s that Haas is the first choice for machinery

across the world. Their reputation thrives on

service and innovation, something dear to

any Kiwi manufacturing company’s ethos”

says Karl.

Haas plans to capitalise on this global

interest in manufacturing and is focusing on

further developing the brand across new

markets with the goal of achieving a $2

billion USD turnover by 2020. For customers

in New Zealand, this means access to Haas’

latest machines and full support packages

supplied by technicians trained in the Haas

factory. “Haas is helping New Zealand

companies get the most out of advances in

manufacturing technology, it’s great to be

part of ensuring the industry here remains

strong and continues to compete on a global

scale”, Karl concludes.

For more information, contact Karl on

09 526 8307.

Haas’ new line of machinery attracts attention.

Students check out one of many demonstrations at the Smartforce Student Summit.

The future of manufacturing materialised before the eyes of visitors to the 30th International Manufacturing Technology Show (IMTS) in Chicago on the 8th to the 13th of September. 112 countries and 2,035 companies were represented in over 1.3 million square feet of exhibition space.

ENGINEERING LEADERS 5


“Materials and composites science and en-

gineering is all about understanding why

solid materials behave like they do and how

to improve them,” Professor Pickering, the

deputy head of the School of Engineering, at

the University of Waikato, says. The essence

of this work is manipulating the properties

of composite materials and natural fibre

composites and modelling their failure, to

create substances with which producers

can do more in today’s high-technology

environment.

Professor Pickering says she has drawn a

lot of inspiration from nature for her work.

“Think of the capabilities of objects such as

trees and shells, the combination and design

of material properties in nature and the way

they function, that we cannot imitate yet.

Think of our bodies – we cut ourselves, and

our bodies self-heal. In materials science and

engineering, these are the kind of proper-

ties we study, the kind of objectives towards

which we are working,” she explains.

Professor Pickering, following her enjoyment

of and outstanding results in science, math-

ematics and craftwork, first interviewed at

the Imperial College of London, where her

brother was studying mechnical engineer-

ing, for chemical engineering. “While there,

I was introduced to materials, and a whole

new world opened up for me, so materials

is what I did,” she recalls. In 1987 she com-

pleted a BSc(Eng) degree.

After four years working for a tele-

communications company, developing

interconnectedness technology by manip-

ulating the qualities of silicon and gallium

arsenide chips for the purposes of refining

thermal imaging systems, she went back to

school in 1991. In 1994 she completed her

PhD in composite materials at Surrey Univer-

sity, then headed towards New Zealand and

a job at the University of Waikato.

This was a leap of faith; when she joined

the staff, there were only three other people

working in the engineering department.

Twenty years on, there are now about 20 ac-

ademic staff members, including a team of

staff dedicated to materials research.

“From the houses we live in and the cars we

drive, to the computers and smart phones

we use, much of our daily activity, comfort

level and to a large degree, even happiness,

relies on our interaction with materials. In

addition, materials science and engineering

is a key driver for technological development

and national economic success,” Professor

Pickering comments.

She explains a key focus for the team of

students and researchers is therefore meas-

urable value addition to the economy by

supporting companies with the develop-

ment of composite materials and polymers

for specific applications. Several of these

research projects stand out for her. Past

successes include a rotationally moulded

weighbridge for livestock, developed in

conjunction with an agricultural supplies

company, and a corrosion-resistant com-

posite used for the storage of petroleum

developed in conjunction with a construc-

tion product producer.

Her favourite projects however are those

involving developing sustainable composite

systems and complementary bio polymers

from natural fibres. One of the products

resulting from that field of study is plastic

clip systems for meat production processes

made from corn gluten meal. Another is sus-

tainable composites for use in 3D printing,

a field in which the team is a world leader.

“We’re looking at developing materials to

give improved performance, using cheaper

systems that more people can access in the

near future. We’ve done some work looking

at reinforcing plastics with sustainable ma-

terials, or using sustainable materials only,

so we can move beyond printing prototypes

to actually making parts that are strong and

stiff enough for in-service use.

“So far we’ve shown we can 3D print com-

ponents from sustainable materials that are

stronger than injection moulded parts, ideal

for one-off and personalised parts, such as a

custom-fitted exoskelet for a broken wrist or

replacing simple broken parts on household

appliances,” she says.

The team also works with Hemptec, a tex-

tile producer, to investigate the potential

of using hemp fibres and New Zealand

harekeke flax in composite materials. A

major market for this kind of work is the

European automotive industry, who uses

this technology for vehicle interior styling to

comply with end-of-life recycling directives.

But Professor Pickering’s pride and joy is a

research project that looks at ways of rea-

ligning fibres in composites to strengthen

building materials. “We’ve had huge suc-

cesses in improving the properties of these

materials. Previously fit to be used for low

structural requirement purposes only, we

now see them so enhanced in strength, stiff-

ness, and load bearing capacity, that they

can be used potentially in applications such

as bridges and airplanes,” she says.

The results are measurable and exciting. A

biodegradable, recyclable, natural short-fi-

bre composite material from the team’s

laboratory has been tested to yield at 100

mPa, compared with common wood tested

parallel to the grain – its strongest point –

yielding at 35-50 MPa and mild steel yielding

at 220 MPa. The steel, however, weighed six

times as much as the composite material,

which leaves the field wide open for novel

applications.

But even more exciting are the results from

the team’s experiments with self-healing

composites. So far, modified carbon expoxy

has proved its ability to self-heal cracks

by reknitting the affected molecules in a

process stimulated by heat application. “Al-

though we’re not getting a 100% return of

strength, it significantly prolongs the life of

the material…and we’re not finished with

the research yet,” Professor Pickering smiles.

She says, since the team’s role is often

supportive to ensure the success of client

companies and the university as a rule does

not make its own products, it is often diffi-

cult to claim credit for successes.

“Our work is behind the scenes. But I am a

natural engineer, I see problems and want to

solve them, like to solve them. As a group

we want to make things better, so knowing

we made a difference is enough in itself,”

she adds.

Professor Kim PickeringKeeping it sustainableAll the objects people use in their daily lives, nature-made or man-made, consist of material, and there is always room for improvement. A fascination with this observation and a passion for science, mathermatics, and craftwork is what turned Kim Pickering’s mind to a career as materials and composites science engineer.

Manufactured from black UL94 V0 silicone

rubber these plugs provide an IP67-rated

liquid-tight seal. These are available in seven

different sizes with mounting holes from

12.7mm to 34.93mm and to suit maximum

panel thicknesses of 3.2mm. These plugs

are easy to install with just fingertip pressure

– no tools are required.

Alongside the range of liquid-tight plugs is a

range of grommets and bushes. Grommets

are used to protect or cover through holes,

helping eliminate sharp edges so wires and

cables are protected. One of the most pop-

ular, polyethylene grommets, come in clear

and colour and have an easy-fit design into

panel holes from 6.3mm to 38.1mm. A

range of rubber grommets is available for

panel holes from 4.8mm to 31.7mm and fit

panel thicknesses up to 1.6mm.

Hi-Q stocks multiple variations of bushes in

miniature, standard, adjustable and open/

close styles. Adjustable bushes close the

entry hole to insects and vermin and adjust

to accept various diameters and shapes.

Open/close bushes are designed for uneven

drilled or punched holes and can be installed

after the cable.

Bushes are manufactured from black nylon

6/6 and are designed to snap quickly into

the panel hole, and fit panel holes from

4.8mm to 50.8mm.

If you are looking for that hard-to-find plas-

tic hardware, it is hard to go past Hi-Q. the

“We are extremely honoured to receive

these three awards. It is great validation for

our staff, who are truly the very best in New

Zealand,” Millennium Plastics general man-

ager Tony Rutz says.

“At Millennium Plastics, we do things a bit

differently. We’re not simply another plastics

design and moulding company. Our exper-

tise lies in working side-by-side with our

customers to ensure their original product

ideas and designs capture the greatest value

for their business and achieve the product

benefits they promise their customers.”

Waikato Milking Systems’ new Electronic

Milk Meter provides accurate real-time milk-

ing data, enabling dairy farmers to improve

herd management decisions and long term

profitability of their herds.

Product design manager Jim Pharaoh says:

“Our first concepts for our electronic milk

meter were developed several years ago.

Several prototypes were trialled on farms

resulting in a computer model that was

submitted to Millennium Plastics for their

critique and manufacture of the meter

which was released to farmers in August

this year.

“The modern milking shed is a very chal-

lenging environment to design for as you

need to develop products to withstand con-

tact with milk, heat, cleaning chemicals and

moisture. Over the years we’ve found that

with careful material selection we can satisfy

all those criteria while also injecting a high

level of innovation and creativity into our

product designs.

“Simplicity is the cornerstone of Waikato

Milking Systems’ design philosophy and

the modern plastics technology Millennium

Plastics uses allows us to make very complex

forms to create simple, effective products.

The end result is that we supply products

to our customers that are both reliable and

fit-for-purpose.”

As part of a third-year mechanical engineer-

ing design paper, 10 teams of students were

each asked to create a prototype machine

that could collect nine metal pins along

a track, then reverse and drop the pins in

a box at the end. The process is designed

to emulate the act of picking pine tree

seedlings.

The winning team’s prototype collected

and deposited the most pins in the fastest

time. The inventions were tested at the

Carter Holt Harvey Pulp & Paper Engineering

Design Show in October.

The winners on the day were Gordon Jack-

son (Paeroa College), Ben Plumtree (Hawera

High School), Nate Ryan and Mark Edwards

(St John’s College Hamilton) with their ve-

hicle named Zeus, which stood out for its

speed and accuracy.

“We think our success was down to utilis-

ing the electrical circuits to allow maximum

voltage through each motor,” says team

member Mark Edwards.

Course lecturer Associate Professor Mike

Duke says the project is a great way for the

students to work on something from start to

finish. “It’s their first chance to experience

the development of a functioning machine

right from concept, to design and build.”

The project is part of a much wider research

collaboration with tree improvement and

treestock production business ArborGen

Australasia. Last year students worked on

prototypes that could distribute one pine

tree seed in each compartment of a seed-

ling tray in the shortest time. In addition Prof

Duke’s research team completed a Dibbler

machine which plants seedlings so that they

grow straight.

“Picking the seedlings in a mechanised way

is just another step in our research project.

For the students we simply asked them to

make machines that could collect seedlings,

but what we’re working on at a higher level

is creating a prototype which uses machine

vision systems to grade the seedlings as it

collects them.”

COMMENTARY 13


‘YOUR LEADING ROTARY SCREW SPECIALIST’

YOUR ROTARY SCREW SPECIALIST

Auckland • New Plymouth • Christchurch • Timaru

Those of the 70-plus SCNZ industry mem-

bers present know of course that I refer to

the introduction of the Steel Fabricator Cer-

tification or in short, the SFC scheme. The

basic element of the SFC quality assurance

scheme is the welding fabrication quality

assurance standard ISO 3834, whose pro-

motion and introduction has been on the

HERA industry development strategy for a

long time.

However, to make it happen needed the

leadership of SCNZ manager Alistair Fussell

and a group of steel construction fabricators

responding to the challenge of much-need-

ed industry innovation, particularly

stimulated through increased threats from

fabricated steel imports to cover capacity

demands from the Christchurch re-build.

Company leadership was required on two

fronts. Firstly at the industry sector front,

the commitment to set up the scheme and

be part of the scheme governance was

required. In this role, the industry group in-

volved wanted to go further than just the

ISO3834-governed welding fabrication area.

It also wanted to cover additional functions

specific to NZ steel fabrication and its stand-

ards framework representing an important

extension into the New Zealand specific SFC

scheme.

On the second and more important leader-

ship front, it was the requirement to drive

company internal processes. Based on the

scheme’s fundamental principle to ensure

that there are appropriately qualified people

in place to run the welding fabrication

and the quality assurance process, training

people was therefore a fundamental re-

quirement for the companies to complete

before they were able to meet the scheme

requirements.

And seeing so many individuals going

through the associated HERA courses and

achieve the required qualifications is a fan-

tastic outcome, and I specifically want to

commend the individuals achieving this and

the companies supporting them.

In this context, it is worth noting that the

individuals and their functions in the scheme

are listed on one of the certificates handed

over to demonstrate compliance. Therefore,

the so named Responsible Welding Co-co-

ordinator is left in no doubt that he/she is

ultimately responsible for the delivered qual-

ity. A task they will be handling with pride,

having been equipped with the tools and

processes to manage these tasks as part of

the training and scheme implementation.

At the presentation ceremony, it was heart-

ening to see entire welding fabrication

teams walk to the front to receive their

certificates from MBIE chief executive David

Smol and HERA Welding Centre general

manager Dr Michail Karpenko, in recogni-

tion for what those teams have achieved in

a very short time.

And in the ensuing discussions with the

bosses, hearing their feedback on the com-

pany’s performance improvement following

the SFC scheme introduction gives me con-

fidence that scheme participation will only

grow across all players of the sector.

Ultimately, the benefits will accrue to

everyone on the supply and end-user side

ensuring a sustainable steel industry based

on the principles of delivering quality, value

and certainty through innovation.

Dr Wolfgang Scholz is the director

of Heavy Engineering Research

Association (HERA).

Steel fabrication industry meets its most significant challenge By Dr Wolfgang Scholz

At its AGM last month in Hamilton, Steel Construction New Zealand (SCNZ) members used the opportunity to celebrate the introduction of the most visible industry transformation process in its sector’s history. Being intimately involved in its development, it gives me great satisfaction to see its introduction happen with such great industry commitment and industry leadership.


14 CASE STUDY

A machinery operator and product designer,

Mr Slee was frustrated with grease nipples

leaking, wearing and jamming. Sometimes

a traditional grease nipple would leak if

it had been scratched or worn from the

teeth inside the coupler. To make matters

worse, the coupler could also become worn,

making it difficult to know whether the

grease coupler or grease nipple was faulty.

“Often a machine operator wouldn’t have

time to replace a worn grease nipple or

grease coupler,” Mr Slee says. “This results

in grease leaking out, leaving a mechan-

ical joint or pin dry. This joint would then

wear out costing big money to refurbish or

replace.”

Mr Slee thought there must be a better way

– a grease fitting system that didn’t wear,

leak or jam would be ideal. However, all

of the systems he considered used locking

mechanisms which tended to jam under

pressure, a situation that was unacceptable.

“It wasn’t until the year 2000 when I was

doing some service work on an agricultur-

al spraying unit that I noticed a cir clip was

missing from an input hydraulic gland on a

hose reel. I was amazed that this hose reel

gland would still operate with no cir clip at

300 psi.

“But would it operate at 10,000 psi with no

cir clip? I went about testing this, discover-

ing that the hydraulic gland on the hose reel

was operating at equal pressure and with

modifications would easily handle 10,000

psi.”

14 years and 500 prototypes later Bradley

has patented/designed a superior grease

coupler and grease nipple that won’t leak,

wear or jam. The grease coupler has a

10-year guarantee and has no internal or

external parts, making it ultra-reliable com-

pared to traditional grease couplers that

have on average 10 parts. The grease nipple

has a 10-year guarantee and an optional sil-

icon dust cap is available.

Here are the top three technical challenges

Mr Slee encountered in those 14 years, in

his own words:

Designing a grease coupler with no

moving parts

“Grease flow channels were needed inside

the coupler. Traditional CNC lathes gen-

erally only drill holes at 90 degrees. This

meant the port holes needed to be capped

by laser welding, but upon further investi-

gation I found a CNC machinist who did

angle drilling. This allowed for the coupler

to be manufactured 99 percent on the CNC

lathe with no welds or joints and no inter-

nal or external parts. All that is required

after machining is chrome plating and laser

branding.”

O-ring seatings

“There is a lot to know about it. My first

seatings were totally incorrect. The O-ring

squeeze was too little or too much. Then the

O-ring groove was too wide or too narrow.

I learnt that rubber is like liquid – it can't

be compressed, it only changes shape. For

example, if the cross section drawing of an

O-ring is viewed, you will see the circular

shape become an oval with zero compres-

sion of the rubber.”

Hydraulic one-way valves

“I wanted no mechanical parts inside the

grease nipple. I designed a special flat

O-ring that I managed to get working at low

pressures. But it was unreliable at extreme

pressures of 10,000 psi. I was forced to go

with a traditional ball valve. I had trouble

with the ball seating also, it would not seal

properly onto a 118 degree face until I used

a ball nose drill. This created a nice concave

for the ball to seat into.”

Website: www.nevaleak.com

2000: First prototype made in Mr Slee’s workshop using some

hand-cut rubber washers as seals to see if equal hy-

draulic pressure would work, and it did. The seals were

on the inside of the coupler. He would get help from

manual lathe machinists for the following prototypes

2001: Tolerances too sloppy between coupler and grease

nipple. O-rings can escape out off gap

2002: Incorrect squeeze ratio for O-rings. Research of O-ring

squeeze charts fixes the problem

2003: Not enough room in O-ring grooves to allow ovaling

of the O-rings. As a result the O-rings got chopped

2004: Manual lathe engineers struggle with internal machin-

ing of the grooves for the grease coupler

2008: decision to drastically reduce nipple size to 6mm.

Access to CAD drawing software. Too much difficulty

in drilling angle holes manually in couplers

How Nevaleak created the grease coupler and nipple that won’t leak, wear or jamBradley Slee caught on a product idea, and worked on it for 14 years until he got the design right. 500 prototypes later, he has patented a superior grease coupler and grease nipple that won’t leak, wear or jam. NZEN editor Romy Udanga spoke with Mr Slee on some the technical challenges he encountered along the way.

2009: Plastic back valves in grease nipple too weak for 10,000 psi

2011: Access to engineers with CNC

lathes. Slots used for intakes on

grease nipple but proved too

slow for economic manufacture.

Traditional ball valve designed for

grease nipple

2012: Laser welding used on coupler

port holes

2013: Drastic decision to swap the

O-rings from the coupler to

the grease nipple. Decision to

use standard 4mm O-rings. Decision to go with stainless

steel grease fittings to avoid tolerance problems when

electroplating

2014: A solid state coupler achieved with no welds and no moving

parts by using a CNC lathe with an angle drilling head.

AUTOMATION 17


Globally, Fonterra produces over 22 billion

liters of milk each year. This requires only the

best resources to ensure high quality milk

is produced in ways that add real value to

Fonterra’s customers and consumers around

the world. The facility in Auckland produces

a number of products including fresh milk,

ultra high temperature (UHT) milk and cul-

tured dairy food for some of New Zealand’s

best-loved brands. The resources needed to

produce these products not only derive from

New Zealand’s natural environment, but also

the equipment used at Fonterra’s Takanini

facility.

More than 90 percent of UHT milk and

cream produced at this facility is exported

to markets in the Pacific and Asia region,

including China, Singapore and the Phil-

ippines. Due to expansion and upgrade in

order to help meet the significant growth

occurring in the global market, the UHT pro-

cessing and packaging facility now draws

between 30 to 40 megawatts of power. This

is mainly drawn by the large AC drives and

motors used in the facility’s production lines,

which package more than 750,000 liters of

fresh milk each day and can produce around

6.4 bottles per second.

Eliminating costly outages

The production lines are sensitive to voltage

sags and short term outages. These short

term outages usually range between 1 to 60

seconds, but the value of uncertain energy

caused by machinery can result in serious fi-

nancial loss. When this happens, there is no

guarantee the milk is sterilised for consumer

use, so disposal or re-processing of the milk

is required.

Fonterra New Zealand’s brand group auto-

mation and control manager Peter Williams

outlines the effect Fonterra’s power quality

events were causing: “When a glitch occurs

in our facility, we need to go through a

sterilisation process which takes around

four hours. An event like this across seven

production lines, costs us 28 hours of down-

time and around $50,000 to our business.

This would typically happen to us two, three

or four times a year.”

The PCS100 active voltage conditioner

(AVC), which is part of ABB’s power pro-

tection portfolio, is able to eliminate these

voltage disturbances in Fonterra’s facili-

ty, eliminating unwanted downtime and

wasted milk product that would ultimately

cause an on flow effect to the food and bev-

erage industry. “We would be looking to see

savings in the amount of $500,000 a year,”

Mr Williams says.

Fonterra decided to implement ABB’s

PCS100 AVC because of the global relation-

ship with ABB and reliability of its products.

“We have experience and a great deal of

faith in their products… after some due dil-

igence, we decided to implement it at our

facility,” adds Mr Williams.

Further benefits of the PCS100 AVC are the

lowest total cost of ownership by requiring

Cutting costly outages for FonterraWhen leading multinational dairy manufacturer Fonterra needed a power protection solution for its processing and packaging lines at its facility in Takanini, Auckland, ABB was able to provide a solution that would eliminate voltage sags and cut out over four power quality events annually, saving an estimated cost of $500,000 per year.

no energy storage and maintaining an oper-

ating efficiency of 99 percent. With a small

design footprint, the PCS100 AVC was able

to fit into the small confined area of Fon-

terra’s equipment room, making it an ideal

solution for facilities that do not have large

amounts of space for their power protection

requirements.

Mr Williams indicates that in the future,

Fonterra plans to utilize ABB’s products to

improve the power quality in other locations

as well. “Over some time we are looking at

using this solution at other UHT sites, just to

guarantee that supply stability we need. Our

mission is to become the world’s most trust-

ed source of nutrition and ABB’s product is a

crucial part of that process,” he says.

18 SPECIAL FEATURE – ENGINEERING IN THE FOOD INDUSTRY

Waterworks Wholesale marketing commu-

nications manager Martin Thomas says the

processing plants selected the Europress

Piping System and benefited from the gen-

erous savings immediately as contractors

were able to install both hot and cold water

pipework as well as gas and chemical lines.

The metric Europress Piping System is a fast

and simple-to-assemble system for 304 and

316 stainless steel and carbon steel pipes,

and can offer piping installation savings of

up to 30 percent because of the speed at

which it can be installed.

”One contractor completed installation of

approximately 240m of 76mm Europress

pipe and fittings as well as pressure testing

equipment in just over one day. Fewer hours

on the job can result in huge savings on an

installation,” Mr Thomas says.

“The installed value is what sets the Europress

system apart. The process has been proven to

save time and money and is safe and conven-

ient. No hot work permits are needed.”

The system produces reliable joints with high

mechanical resistance and is used by the full

spectrum of industry for civil, industrial and

naval pipework system installations.

“Since its launch in 2002 in Europe, it

has revolutionised traditional installation

techniques in respect of quality and price

competitiveness,” Mr Thomas says. The

range is available in diameters ranging from

15mm to 168mm.

The Europress secret is the toroidal seat,

which when pressed seals a joint in two

stages. Mr Thomas explains: “The first radial

stage compresses the O-ring and guaran-

tees that the pipe is hermetically sealed. The

second, final stage is a geometric compres-

sion of both fitting and pipe, which creates

a mechanical joint that is resistant to both

lineal and rotational movement.

“Each joint has a highly visible press check

sleeve that allows the installer to determine

at a glance that all joints have been success-

fully crimped. Competent installers working

with the Europress range of portable 18v

hand held crimp tools can install the system

up to 10 times faster than highly specialised

welders can install systems that require con-

ventional TIG welding techniques.

“The use of original Europress fittings with

the correct pipes and approved pressing

tools, coupled with strict adherence to the

technical instructions given for both the

design and installation of the system, will

guarantee reliability in every joint and the

longevity of the system,” he says.

Premium testing authorities in Australia,

Austria, Denmark, England, France, Germa-

ny, Italy, Netherlands, Norway, Sweden and

Switzerland have awarded Europress Piping

Cedenco Foods, Gisborne-based producers

of food ingredients such as pastes, pow-

ders and purees from locally-grown fresh

fruit and vegetables, has been upgrading

their operations as part of their overall

growth strategy. With more produce pass-

ing through the facility, more overseas and

domestic sales and an anticipated 100 new

seasonal positions, Cedenco has been devel-

oping ways to work smarter. One tactic is

investing in new technology.

“Over the last few years we have introduced

bar-code scanning to help us track the bins

of produce as they move through the fa-

cility,” says Cedenco Foods information

technology manager Cleon Pinto.

“In the past we used a paper-based system

that took too much time with manual

note-taking. So we installed a limited wifi

network to support hand-held scanners.

We now attach bar-codes on each bin and

then use the scanners to track invento-

ry as the bins are shifted. We found that

this approach was faster, easier and more

accurate…so much so that we made the

strategic decision to expand wireless scan-

ning and wifi coverage across the entire

complex.”

Significant expansion

Cedenco has been on an aggressive growth

path. One initiative has been the construc-

tion of a new 3000 sq m processing factory,

including frozen goods storage, next to their

existing facility. “As we were expanding

scanning and wifi capabilities here,” con-

tinues Mr Pinto, “we looked at options to

include the new factory in our wifi coverage.

We were especially interested in finding an

AP that we could use in the cold storage…it

operates at -18 degrees C…as cold storage

is a key part of the business.”

Cedenco Foods and the team at Fujitsu’s

Gisborne office have been working togeth-

er on ICT projects since the early 2000s and

have enjoyed a ‘trusted partner’ relation-

ship. “Cedenco asked us to submit a bid to

expand wifi coverage at their current facility

with the idea to extend it to the new facto-

ry when they were ready,” says Fujitsu New

Zealand network support specialist Andy

Memmott.

“We had already installed a Fortinet Forti-

Gate 110C UTM Appliance that they used

primarily as a firewall and to provide net-

work security. Their current wifi gear was

not designed for industrial applications so

they were open to suggestions.”

“One of the features of the FortiGate

110C is the wireless controller,” notes Mr

Memmott, “so they already had all of the

management and monitoring capabilities

in place to control more than enough For-

tiAPs to cover the entire footprint of both

factories. So it was the logical decision to

recommend that Cedenco standardise their

AP constellation with Fortinet equipment.”

“We did a thorough site survey and identi-

fied a series of locations that would provide

the widest coverage with the fewest APs,”

he continues. “We took advantage of the

FortiAP’s dual-2.4/5GHz capabilities to

provide enhanced coverage as well as PoE

(power over Ethernet) to facilitate installa-

tion. We were able to give them the initial

coverage they wanted by proposing three

pole-mounted outdoor-certified FortiAP

222Bs. And since their FortiGate Appliance

was already installed, the total cost was

quite affordable. Plus the 222Bs are rated to

-25 degrees C,” he says.

“We wanted wider coverage, trouble-free

operations and affordability,” Mr Pinto says.

“In addition, we had existing infrastructure,

including a FortiGate 110C UTM Appli-

ance, that we wanted to leverage. When

we looked at all of the options, Fujitsu’s

recommendation that we standardise with

Fortinet access points was the most advan-

tageous choice.”

Fast installation, robust operations

Cedenco’s own internal technical team

carried out the actual installation with Fu-

jitsu providing configuration and support

services. “The install went very well at our

facility at the time,” says Mr Pinto. “That

was about a year ago. Everything worked as

specified. And as the new facility was being

built, we installed additional APs to cover

that area as well. The new facility opened in

February 2014. It’s interesting to note that

we did install one AP in the cold storage

room and it is operating without a hitch. So

now we have coverage over most of the two

facilities and it has provided a backbone for

scanning which has in turn allowed us to

process more food in less time.”

As Cedenco moves forward with other in-

itiatives, it will take further advantage of

its wifi network. “We plan on using wifi to

enable managers to roam throughout the

facility with their laptops, but that will come

later,” Mr Pinto concludes.

Cedenco Foods selects Fortinet Access Points for major expansionTo provide wifi coverage in their new NZ$6 million produce processing facility and increase signal strength within their existing adjacent factory, Cedenco Foods selected an array of Fortinet FortiAP 222B Access Points.

Total wifi coverage made hand-held scanners more effective tools at Cedenco Foods


20 SPECIAL FEATURE – WOMEN IN ENGINEERING

While 2013 census data shows 13 percent of

engineers in New Zealand are women now-

adays, figures from universities and technical

institutes show that will change dramatically

soon. The University of Auckland’s School

of Engineering had a 2013 Level 1 intake of

25 percent female students; New Zealand’s

national average was 23 percent. On top

of that, 13 percent of learners completing

Levels 5 to 7 diplomas in engineering and

related technologies were women, as were

30 percent of learners completing similar

Level 4 certificates.

Ms Smith, a civil engineer with HEB, says

when she started out she faced “road

blocks” but had no one in a similar position

to talk to about it. With the birth of her

first child in 1999, she was forced to move

into consultancy because the contractor she

worked for wouldn’t offer part-time work.

“At the time they were closed to the idea.

If someone had been there to show me the

way I could have had wider options. I’ve

worked for three different companies over

eight years, all part-time, and I’ve found the

larger ones definitely see it as something

they can offer. With the current skill short-

age, organisations understand they need

to do what they can to hold onto key em-

ployees. And if women find their employer

doesn’t offer this – look for someone who

does!”

Ms Sinclair, chief engineer at Auckland

Council’s Infrastructure and Environmental

Services, is mum to a teenage daughter

and has always worked full time. As a new

parent she was very lucky to work for a

company who had an uncommonly high

percentage of female engineers. “Even back

in the day” they automatically provided lap-

tops to mums. They understood the value of

employees, she says.

“But you have to choose the right employer

and before you do that you need to work

out how you want to be a parent. It’s a two-

way street. Once you’re clear on this you can

find an employer to work with it.”

Ms Eldridge, a full-time working mum with

two young boys is head of Waste and Indus-

try at the employee-owned Tonkin & Taylor.

She suggests thinking twice about working

full-time if the main reason you’re doing it is

for another full-time salary, as you typically

spend “a great deal on the children to make

sure they are happy and well cared for”. She

says that her company provides laptops for

home use and other flexible options for par-

ents who need it.

So far, female engineering students haven’t

been formally introduced to the issue; while

studying engineering they have no support

problems at all, but once in the workplace,

some women feel isolated. This is where

Women in Engineering (WIE) networks have

begun to do a lot of work. The University of

Auckland and University of Canterbury both

have them and the Institute of Professional

Engineers New Zealand collaborates with

them.

Dedicated WIE advisors recruits girls into

the courses, offer support if they want it,

and build strong links with schools, forming

bonds with industry and companies so that

Dr Wicaksana’s background in membrane

technology, in particular membrane fouling

propensities, gives her expertise that has

applications within many of New Zealand’s

key export markets – she is currently focus-

ing on applications of membrane processes

for the food industry, and is already work-

ing with a New Zealand dairy company on a

project related to membrane fouling control

strategies.

“It’s exciting as an engineer to be able to

apply your research to real situations,” says

Dr Wicaksana, whose PhD, undertaken at

the University of New South Wales, gave her

the tools to explore not just membrane tech-

nology for its own sake, but the potential

and actual applications of membrane tech

nology for industry – in particular food pro-

cessing and wastewater management. Dr

Wicaksana enjoys being able to contribute

to New Zealand via her work – “food pro-

duction is very important to New Zealand

– this motivates me to apply my research

to the dairy industry and the food industry

in general.”

But she’s not content with just working on

individual projects related to membrane

technology in food production applica-

tions – Dr Wicaksana would like to develop,

over time, a membrane technology re-

search group at the University of Auckland,

closely linked with industry, and that can

address real and critical industry need in

New Zealand. A research network that in-

cludes industry partners would enable her,

with colleagues, to undertake great, indus-

try-based research that answers industry

problems.

Engineering yields to family needs By Sally Webster

When engineers Nicky Smith, Sarah Sinclair and Simonne Eldridge got up to talk about balancing engineering and raising children at the University of Auckland’s School of Engineering in September, it highlighted a steadily changing gender balance and warned employers to start thinking about family-friendly policies.

Making advances in membrane technologyDr Filicia Wicaksana, who arrived in New Zealand in 2013 as a lecturer with the University of Auckland’s Chemical and Mechanical Engineering Department, is excited by the prospect of developing a research programme that has direct and tangible benefits for New Zealand industry.

The filter-through effect of more women

Coronary artery disease is the most common

killer in the Western world, Ms Beier says.

“One in four people will die from a blockage

in one of the coronary arteries, preventing

supply of blood and oxygen to the heart.”

A common treatment for narrowed arter-

ies is ‘Percutaneous Coronary Intervention’

(PCI), where a wire mesh tube, or stent,

is inserted into the narrowed vessel and

expanded to hold it open. This is a highly

effective and low-risk treatment, is relatively

non-invasive and enables rapid improvement

in the patient’s condition.

Unfortunately, stents fail in more than 25

percent of patients, when the previous nar-

rowing reoccurs with the stent.

New stents that release medication (known

as ‘drug-eluting’ stents) promised a solution

to this problem, with the slow local release

of drugs suppressing the regrowth of the

tissue responsible for re-narrowing. A short-

term improvement is achieved, but late

failure rates increased significantly, which

carry the risk of causing sudden death.

It is known that the presence of the stent

changes blood flow, which in turn alters the

growth of tissue, and thereby affects treat-

ment outcome. Currently, there are more

than 250 different stent designs available,

each of which has a different effect on the

3D blood flow pattern.

The stent design is therefore critically im-

portant in determining treatment success or

failure. Clinical trials with groups of patients

have been unable to define the stent design

features determining success or failure due

to the complexity of the problem. More

detailed quantitative analysis is needed to

answer the question of how different stent

designs affect the complex blood flow in the

coronary arteries.

“My research aims to study the link between

flow (haemodynamics) they cause, and

says. “Improving stent design by measuring

the impact on blood flow may significant-

ly reduce stent failures and ultimately save

lives.”

baby is sick, I ring up and ask for the day off

and it is never a problem. I also have flexi-

bility of when I arrive in the morning,” Ms

Chow says.

are Watercare’s Wastewater senior engineer,

Maire Lenihan and Head Works manager

and mum of three, Suzanne Naylor. Water-

care employs twice the women engineers

it did in 2007 and now women make up

20 percent of the CCO’s female engineers

overall.

“I found in the early stages I had to work

so hard – more so than anyone, so that

whenever I was challenged, I could justify

my thinking,” says Ms Lenihan. She has no

plans to start a family yet and wonders if she

did so, how she would be able to work full-

time and responsibility sign off on $1million

spending decisions in anything less than

full-time hours. Ms Naylor agrees it’s tough,

saying this is why her husband decided to

be a stay-at-home dad and support her in a

promising career.

She says it took a long time to gain the

men’s trust and doubt would always set in

again once she became obviously pregnant.

“There is immediately a negative conno-

tation when you turn up to a meeting

pregnant. It was really hard at times – some

of the guys think you’ll be hormonal and dif-

ficult to deal with.”

achievement saw her win it’s Young Profes-

sional of the Year award in 2010.

WORKSHOP 23


In times of ever-shorter product life cycles

and increasingly more complex and more

individualised components, generative man-

ufacturing processes can help companies

produce new and innovative products more

quickly. The unique technology combination

of laser deposition welding by means of a

powder nozzle and milling gives the user

completely new application and geometry

options. With the LASERTEC 65 3D DMG

MORI now offers a hybrid solution for com-

bined laser deposition welding and 5-axis

milling.

The market for additive processes has

grown rapidly in the past. However, up to

now these processes have been restricted

to the production of prototypes and small

parts, which could not have been manufac-

tured using conventional methods. With the

combination of the two processes, metal

deposition and metal removal, on one ma-

chine additive technology complements and

enhances traditional machining methods.

To enable generative manufacturing, the LA-

SERTEC 65 3D is equipped with a 2kW diode

laser for laser deposition welding, while

the fully fledged 5-axis milling machine in

robust monoBLOCK® design also makes it

possible to carry out highly accurate milling

operations.

Among the highlights of LASERTEC 65 3D’s

features are:

• Intelligent combination of laser deposi-

tion and milling enables maximum surface

finish and component precision

• Laser deposition welding with powder

nozzle: up to 10 x faster than powder bed

processes

• Feasibility of complete 3D components

with diameters up to 500 mm without

any supporting geometry, even with over-

hanging contours

• Direct machining of areas that are no

longer accessible on the finished part.

Producing large parts generatively

In contrast to laser melting in a powder bed,

laser deposition welding enables large parts

to be manufactured using a metal powder

nozzle. With a deposition rate of up to 1

kg/h, this process is up to 10 times faster

than the laser generation of parts in a

powder bed.

The hybrid machine combines the advan-

tages of milling, such as high precision and

surface quality, with the flexibility and high

deposition rate of powder deposition weld-

ing. “In the case of integral components,

where today 95 percent of the material is

removed by milling, with additive processes,

material is only built up where it is needed.

This leads to significant savings in raw ma-

terials and costs,” explains Sauer Lasertec

sales director Friedemann Lell.

The laser, complete with powder deposi-

tion head, is fitted into the HSK toolholder

of the milling spindle. It can be automati-

cally parked in a secure docking station

while milling operations are being carried

out on the machine. The machine and pro-

cess are operated and controlled by means

of the new 21.5” ERGOline® control with

CELOS and Operate 4.5 on Siemens 840D

solutionline.

Production of 3D contours

Using a laser diode, the metal powder is de-

posited in layers onto a base material and

fuses with this without pores or cracks. The

metal powder forms a high-strength welded

bond with the surface. A coaxial inert gas

prevents oxidation during the build-up

process.

One strength of this process is the option

of successively building up layers of different

materials. Wall thicknesses of 0.1 mm to 5

mm are possible depending on the laser and

the nozzle geometry. Even complex 3D con-

tours can be generated with any supporting

geometry.

The individual layers can then be accurately

machined before the areas become inacces-

sible to a cutter or other tools due to the

component geometry. The combination of

the two processes is a sensible choice for

repair work and the production of tools and

moulds. However, it also offers many inter-

esting options for lightweight components,

prototypes or small series production – par-

ticularly in the large-part manufacturing

sector where other additive manufacturing

processes cannot be used due to limited

space.

Economical solution

Large machines, such as those used for ma-

chining bulky components in the energy or

aerospace industries, tend to be expensive.

So the possibility of carrying out roughing,

deposition and finishing on a single machine

therefore represents a financially advanta-

geous solution for the customer. Another

example here is the energy and oil industry

where components often have to be coated

with corrosion-resistant alloys to protect

them against wear. Deposition welding pro-

vides protection for products such as pipes,

fittings, flanges and special constructions

that are used in aggressive environments.

With a hybrid solution, machining of the

base material, coating and finishing can be

carried out on one machine. This results in

cost savings and a reduction in throughput

times.

24 DESIGN

“We’re delighted at winning three ac-

colades,” says Gallagher Security chief

technology officer Steve Bell. “The Gal-

lagher T20 Terminal has a highly innovative

design, utilising advanced over-moulding

techniques to deliver a very robust, envi-

ronmentally protected device, designed

to complement both internal and external

decor. The T20 is a product we’re ex-

tremely proud of, and for our team, this

recognition is well deserved.”

The T20 front fascia incorporates a per-

fectly flush lens for protection of the LCD

screen behind it. The lens is created by

over-moulding clear polycarbonate over

the top of a black or white substrate. This

method gives a deep lustre, elegant lines,

and incredible robustness due to all the

design elements being embodied in one

solid part.

Combating warp

All thermoplastics undergo a size change

as they solidify in the mould. This shrink-

age is often benign and when uniform it

is easy to compensate for it in the tool

making process. At the outset of the

design stage, it was identified that in the

unique case of the T20, something more

advanced would be required.

The clear polycarbonate over-mould is

almost entirely on one side of the sub-

strate, and ordinarily this would cause the

resultant part to warp significantly. If de-

signed in the conventional way, the parts

would have been unusable. They would

have been warped into a dish shape, and

unable to fit into the assembly and per-

form other functions.

Using Finite Element Analysis (FEA), the

degree of warp was determined for a

range of moulding conditions and mate-

rial combinations. The FEA results were

then compared with real-life parts in a

simplified ‘rapid learning cycle’ experi-

ment using prototype tooling. The theory

matched the (simplified) reality, so work

commenced in applying ‘reverse warp’ to

the T20 parts proper. The idea being that

if the parts were going to dish by a certain

amount, Gallagher R&D could design them

domed in the other direction by precisely

the same amount, such that the resultant

mouldings would end up perfectly flat.

It worked. But it is no easy thing to design

an entire product as an accurately reverse

warped version of its future self.

Producing the injection mould tooling was

no picnic either. The tool cavities for both

substrate and over-mould tools have no

straight lines, no flat surfaces, and no truly

circular holes. An extremely high quality

surface finish was also required.

Combating substrate erosion

Conventional over-moulding usually

employs a relatively soft, relatively low

melting temperature over-mould com-

pared to the substrate, so that it does not

erode the underlying material during the

injection phase of the cycle.

The T20 front fascia in contrast uses poly-

carbonate as the over-mould, which is a

rigid material injected at the fairly high

temperature of 300 degrees C. The sub-

strate material is a coloured version of the

exact same material, which gives insepa-

rable bonding of the two layers as they

literally melt into one another.

A little melting is good, but too much

leads quickly to the phenomenon known

as substrate erosion. This is where the

over-mould gouges away the substrate

as it flows across it, around it, and in sev-

eral deliberate places on the T20 fascia,

through it.

Again, Gallagher R&D were able to predict

this in advance with FEA, and make the

necessary geometry adjustments so that

the issue was resolved before any waste

was incurred.

Gallagher’s security solutions are regularly

recognised for quality and innovation in

awards across the world. The Gallagher

T20 Terminal was released to the global

security market in July 2013.

Process attributes

Below are the attributes of a cutting pro-

cess that are most often important from a

metal fabricator or job shop perspective

and a brief description of each process.

Go online at http://www.engineeringnews.

co.nz/content/determining-the-best-pro-

cess-for-metal-cutting/ to see the detailed

attributes of these processes, including

a comparative ‘complete system’ capital

equipment cost.

• Capital equipment cost

While each of these cutting processes re-

quires relatively sophisticated CNC motion

control and fume control equipment as

well as CAD and CAM software packages

to unlock the best potential, there are dif-

ferences in these requirements for each

process. As an example, motion control sys-

tems on a laser designed to cut thin steel at

very high speeds are required to have much

greater accuracy compared to the motion

control system for waterjet or oxy-fuel that

operates at much lower cutting speeds.

These requirements have a direct and often

large effect on capital equipment cost differ-

ences between these technologies.

• Cutting cost per part or per metre

This type of cost calculation must include

consumables (gas usage, consumable noz-

zles, electrodes, garnet abrasive, etc.) and

utilities, (electricity, water, etc.) In some

cases, amortised capital equipment cost

may also be included, as well as labour cost

(such as for loading fresh sheets, or unload-

ing cut parts and scrap). It is necessary to

ensure that the same type of inputs is used

for each system when comparing the rel-

ative cutting costs of each. The cut costs

should be broken down to per metre or per

part as opposed to cutting cost per hour, as

this levels out the speed advantages that

some processes have on some materials.

The cutting cost-per-metre calculations will

always show large advantages to the pro-

cesses with the cut speed advantage.

• Ease of use

This attribute puts the heaviest weight on

the software (especially CAM) as well as the

CNC control capability. Today’s best technol-

ogy systems have relatively short learning

curves and have developed embedded ex-

pertise in the systems, often minimizing the

need for expert operators. While difficult to

put a value on these types of advantages,

it is necessary to think about this when in-

troducing sophisticated systems on the shop

floor.

• Productivity

Often also called throughput, this is essen-

tially the number of parts that have been cut

to specification at the end of a shift. Produc-

tivity or cut speed is the biggest influence on

the real cost per part and, in some cases, ac-

curacy specifications of cut parts (that may

have been tighter than necessary) can be

reduced in favour of a process that provides

dramatically lower cut costs and a bigger

pile of parts in a shorter period of time.

• Cut part accuracy

There are many ways to measure the accu-

racy of the wide variety of parts produced

in metal fabricating. Often the outside

contours of parts have much looser toler-

ances as compared to inside details such as

holes. Also, often times, only the top of a

part is measured, yet the bottom (based on

edge taper) will be substantially different in

dimension. For simplicity, plus or minus ex-

pectations for tolerance as measured from

the top of the part will be used here, as well

as a reference to edge angularity for each of

the processes.

• Edge quality and metallurgical effects

All of these processes will produce some

different effects on the cut edge metallur-

gy that can affect machinability, formability

and weldability.

• Service and maintenance requirements

Some of the long-term operating cost calcu-

lations with each form of these systems will

be affected by the need for maintenance,

as well as the level of expertise required to

perform that maintenance.

Oxy-fuel

The oxy-fuel cutting process is by far the

simplest of the cutting technologies being

discussed. The process essentially uses a fuel

gas to heat steel to its ‘kindling’ temperature

of around 980 degrees C. Once the steel is

at this temperature (preheat), a pure oxygen

jet is activated to create an exothermic re-

action with the hot steel, rapidly eroding

the steel. Oxy-fuel has the ability to cut

only mild steel, and does a good job in the

thickness range 6 -150 mm. Cutting speeds

are better than other processes on materi-

al thicknesses over about 50 mm. It is easy

and inexpensive to add multiple torches to a

CNC machine to increase cutting speeds by

cutting multiple parts simultaneously.

High-definition plasma

High definition plasma uses a high temper-

ature ionised gas to produce a high energy

density cutting arc that is capable of cutting

any conductive material. The latest tech-

nology systems can be almost completely

automated to eliminate the need for oper-

ator expertise and do their best work on 0.5

– 50 mm steel thickness with a maximum

up to 80 mm, and do well on steel and al-

uminium from 0.5 mm through to 160 mm

thickness.

Determining the best process for metal cutting: plasma, oxy-fuel, laser or abrasive waterjetHypertherm designs and produces three of the four major metal sheet and plate cutting processes used in a wide range of metal cutting applications, and is regularly asked which is the best system to use for a given application or range of products. The answer is not always simple and does not always involve just one of these processes. In reality, none of the processes are perfect in respect to their capabilities for handling all cutting requirements; rather, each has its niche area that may involve a thickness range, cut part tolerance advantage, metallurgical advantage or an outright speed/productivity advantage.

3 kW fibre laser

Fibre laser cutting systems are the latest

technology in laser cutting. These systems,

using a solid state laser generator or power

source, are far more efficient than the CO2

laser systems that they are quickly replacing

in the field.

Furthermore, fibre lasers operate at a light

wavelength that allows them to deliver

the beam to the cutting head using a flex-

ible (fiber optic) cable, as compared to the

mirror and tube delivery system used by

CO2 lasers. This provides a simpler com-

plete system layout which requires far less

maintenance as compared to the older tech-

nology. The laser uses a properly focused,

high energy laser to melt a small spot on the

material being cut, and an assist gas (typi-

cally oxygen for cutting steel) to remove the

molten metal. A 3 kW fibre laser can cut

with similar speeds and power to a 4 to 5

kW CO2 laser, indicating its better efficien-

cy. Cut capability on steel is from thin gauge

to about 20 mm.

Abrasive waterjet

Waterjet technology has been in use for

decades for cutting a wide variety of mate-

rials from cake to granite. Softer materials

can be cut with a pure high pressure wa-

terjet (2,750 – 4,135 bar) forced through

an orifice to increase its velocity and energy

density. Abrasive waterjets inject an abrasive

(usually garnet) downstream of the orifice,

so the abrasive becomes the `teeth` of the

saw, propelled by the waterjet to do the

cutting job. Today`s best technology systems

have pumps that can boost water pressure

to as much as 6,900 bar. Higher pressure

means higher cutting speeds, but this has

historically increased downtime for mainte-

nance (pump seals fail periodically and must

be replaced). The latest technology systems

have improved rebuild ability, allowing for

minimal downtime for maintenance. Huge

advantages for abrasive waterjet over other

processes are that no heat affected zone is

produced and its ability to cut almost any-

thing. In addition waterjet provides the best

tolerances. The biggest downside of wa-

terjet is that the cutting speeds are lower

compared to the other processes.

Summary

Selecting the best cutting process depends

on the specific application, the business

needs and other critical factors.

Oxy-fuel is limited to mild steel and is not

effective on stainless or aluminium. It is typ-

ically used for very thick plate.

Plasma provides an optimal mix of cut qual-

ity, productivity and operating costs for mild

steel, stainless and aluminium across a wide

range of thicknesses.

Laser provides excellent cut quality and pro-

ductivity on material less than 6 mm and can

be used up to 20 mm.

Waterjet can be used to cut a wide variety

of materials including steel, stone, granite,

food, etc. It provides the best tolerances and

there is no heat affected zone, although cut

speeds are lower.

The plates – made of hundreds of kilos

of steel and often weighted down fur-

ther with accumulated debris buildup

on top – are traditionally loosened by

mechanics who have to crawl under-

neath giant machines to line up the

bolt holes. Deaths and scores of crush

injuries have resulted over the last 10

years.

A solution to the problem is offered by

Safety MITS’ Tracked Elevating Device,

TED, which eliminates the human

element from the critical lift stage un-

derneath equipment, by employing

remote control of the lifting device.

TEDs can travel across any terrain and

can safely lift up to 800kg. They have a

360-degree turntable at the top, which

makes lining up ball joints safer, quick-

er and easier than the conventional

methods using slings and chain block,

says Timothy Lightfoot, product devel-

opment director at Safety MITS, which

markets the product to global markets

including New Zealand.

“In addition to making belly plate removal

safer, it also makes it significantly more ef-

ficient. Safety MITS collected customer data

from Thiess, Peabody Energy and Glencore

over a one year period and found that by

using TED to remove and install belly plates

they were able to reduce work time by 73.5

percent while using one less mechanic,” he

says.

These savings don’t just apply to belly plates

either. TED can also be used for equaliser

bars, cutting edges, steer cylinders, load

rollers, sound suppression equipment,

engine sumps and many other applications.

TED is designed and manufactured to with-

stand the harsh environments that heavy

equipment works in every day around the

globe. It is built with total compliance to

Australian and New Zealand mining stand-

ards (ASNZ 4240), which are respected

globally. TED comes with a range of at-

tachments, which can be easily installed

and removed at a moment’s notice. These

include:

• The Rhino Stand Locator, which allows

users to locate stands underneath elevated

bulldozers without crawling underneath

the suspended load.

• The Cutting Edge tool, which has been

designed to assist in the safe removal and

installation of cutting edges on bulldozers,

graders scrapers and loaders.

• The Load Roller Cradle, which is de-

signed to assist in the easy removal and

installation of track roller components on

bulldozers, drills and excavators.

• The Tie Rod and Steer Cylinder Cradle, which

is designed to assist in the safe removal and

installation of steer cylinders and tie rods.

The cradle conveniently bolts to the turn-

table on top of TED allowing it to rotate

360 degrees.

This was the situation for a horticultural

engineering company and an engineering

firm that acquired a new injection moulding

machine.

“The horticultural engineering company

wanted a sprayer – but not just an ordinary

sprayer,” Hyspecs sales engineer Andrew

Magon says.

“The requirements are for it to be self-pro-

pelled, the spraying unit had to fit below a

canopy, and allow an operator to sit in a re-

clined sitting position to drive it.”

Mr Magon, who loves the opportunity to

build something new, discussed the client’s

requirements with Christchurch-based Hy-

specs South Island branch manager Owen

Ladbrook.

Starting with Hyspecs in late 1998, Mr

Ladbrook holds a Bachelor in Mechanical

Engineering degree. He has experience in

production machinery design specialising

in manufacturing processes and machine

commissioning, and has particular interest

in machine controls and enjoys bringing ma-

chinery to life.

Mr Magon worked with Mr Ladbrook to

design the sprayer that their client had

thought up. The Hyspecs Service department

was then deployed to build the sprayer.

The project was successfully commissioned

by Mr Magon and the team at Hyspecs.

“It was a successful combination of the

horticultural engineering company’s brilliant

idea and expert manufacturing by the Hys-

pecs team,” Mr Magon says.

In the second case, the engineering firm that

acquired a new injection moulding machine

needed a hydraulic power pack (HPU), and

approached Hyspecs sales engineer Scott

Clemens. The company has used Hyspecs

before and knew that it could design and

build the power pack that is needed.

Mr Clemens took charge of the project with

the aim of delivering high accuracy and

quick setup times, he developed a suitable

design that uses a machine controller, HMI

touch-screen and high-performance pro-

portional valves. He then worked with the

Hyspecs Service team to build, deliver and

commission the HPU.

When you need electronically con-

trolled hydraulic driven power, call

Hyspecs to discuss your requirements on

0800 497 732.

Built from scratch

When you need a specialised piece of machinery, and can describe what you want and need it to do, but it doesn’t exist, what do you do? Hyspecs’ answer? You build it from scratch.

30 ENVIRONMENT

The Opus Wind Tunnel is used primarily for

environmental testing of wind flows around

buildings and new developments. It has also

been used for one-off projects such as ex-

amining the wind flow around cricket balls

for swing bowlers, testing the strength of

different umbrella designs and looking at

snow drift around buildings at Scott Base in

Antarctica.

The wind tunnel has a recirculating config-

uration with a 3m by 1.5m cross-section,

computer-controlled instrumentation and

data acquisition systems, and an extensive

reference library acquired from over 40 years

of analytical investigations, modelling and

full-scale testing.

Common wind issues resulting from new

building developments include people and

amenities being blown around at street level;

noise resulting from sharp edges, shape

geometry and the volume of spaces wind

is forced to flow through; and damage to

cladding, facades and other design features.

Such issues derive from building design and

alterations,and can be readily identified and

mitigated through testing in the Opus Wind

Tunnel.

In studies of wind flows around buildings

and new developments, for example, the

force that pedestrians feel is proportional to

the wind speed squared; so if you double the

wind speed, the force increases by a factor

of four. Increases in wind speed from an ex-

isting gust speed of 10m/s to 20m/s are not

uncommon, with one of the biggest wind

effects being an increase in gust speed from

17m/s to 35m/s.

Examples of wind tunnel investigations in-

clude the effects of strong winds around

the Novotel Auckland Airport Hotel which

were causing stoppages and performance

problems with the building’s revolving

door entry. Mitigation strategies including

changes to the existing canopy and various

combinations of vertical screens and fences

were investigated in the wind tunnel. Short

vertical screens located close to the entrance

were recommended as a result of the study.

The original design of the Majestic Centre,

Wellington was a tall, rectangular shape

with hard edges. When it was tested in the

tunnel the wind effects at ground level were

extreme and unsafe for pedestrians. Opus

Research and the designers played around

with the shape and ended up with the

round, smoother design it now is. However,

wind effects around the building’s entrance-

way were still problematic so Opus Research

designed a perforated, space-frame canopy

which effectively breaks up the wind as it

comes down the front of the building.

When the original design for Westpac Sta-

dium in Wellington was put through the

Opus Wind Tunnel there was too much wind

loading on the roof, which meant it would

have needed to be extremely strong and ex-

pensive. As a result of tunnel testing Opus

Research designed an offset leading edge to

the roof which drastically reduced wind loads

and enabled the design and build of a lower

strength/lower cost roof. They also designed

the slatted metal screens on the walkway

from the stadium to the train station which

reduces wind impact on pedestrians.



The wind tunnelExamining wind flows at the Opus Wind TunnelEarlier this year Opus Research relocated to new premises in Petone, Wellington, where it built a brand new boundary-layer wind tunnel – the only commercially owned and operated wind engineering facility in New Zealand.

WA Stroud’s workshop manager, Gert Visser,

says the most notable of these is the tool’s

ability to coat complex geometries with out-

standing efficiency and quality, even in the

most challenging environment. “In the two

years WA Stroud, Gema’s sole New Zealand

agent the past decade, has been selling the

product, we’ve had excellent feedback on all

its functions, but this feature has been men-

tioned most often,” he says. He explains

how the OptiFlex 2 B works and how its fea-

tures enable it to achieve its performance.

The robust steel construction, mobile cart

unit delivers fast turnaround for small to

medium production runs, in particular when

colour change is a critical part of a company’s

powder coating operation. Designed to use

the powder manufacturer’s original carton,

an inclined vibration table that fluidizes the

powder allows complete emptying of the

powder box via the suction tube. The tube’s

improved design provides consistent powder

flow, ensuring a more stable powder cloud

and consequent smoothly uniform finish. In

addition, the suction tube’s small diameter

assists fast, thorough cleaning.

The tube transports the fluidized powder to

the die-cast zinc powder pump, which has

a new ultra-efficient 45-degrees design that

optimises air consumption from the 85psi

compressor. This results in the consistent

delivery and faster flow of even heavier

powders such as zinc undercoat or urethane

topcoat. Aiding the OptiFlex 2 B’s precision

coating abilities is another new feature –

three digital air valve controls on the pump

that ensures powder flow is constant, result-

ing in a more even, silkier coat.

Mr Visser demonstrates how the industrial

strength yet lightweight, ergonomically de-

signed gun provides good in-hand balance.

“The one piece gun body design allows un-

hindered flow of powder. In addition, the

true 100kv of first pass power in the cas-

cade efficiently charges all types of powders

and improves wrap and transfer efficiency to

among the highest in the industry.

“New-generation Gema nozzles provides

optimal powder distribution and penetra-

tion. This means more power on the work

piece, and less powder in the recovery

system,” he says.

The equipment also features PowerClean™,

a new technology that cleans the entire

powder path from the pump to the gun tip.

On-gun remote control gives the operator

the flexibility to adjust parameters without

turning away from the job and easily activate

the PowerClean mode. “Using powerful

blasts of air (30 Nm3/h), OptiFlex not only

improves performance when spraying chal-

lenging powders, but makes cleaning and

colour changes easier,” Mr Visser says.

But the feature that has users talking is the

controller, set on the industry’s first 360-de-

grees rotating control unit. It offers three

standard programs. These are flat parts,

profiles, and recoating. In addition, it has

25 other programming options through its

precision charge control (PCC) function that

allows the user to set powder output, air

volume, current and voltage, and save them

for recall at any time. “The PCC feature en-

sures not only precision control of current

and voltage that allows maximum efficiency

and uniformity of coating, but also greater

accuracy and adjustability of current settings

below 10 µA when working with challeng-

ing powders such as metallics and special

effects.

“This means the Faraday Effect and the

manual effort that goes into preventing it

is something of the past,” Mr Visser says.”

Feedback from users of this consistent seller

also indicate that the PCC current settings

help eliminate back ionisation, or cratering,

on recoats.

The optional SuperCorona® collects and

neutralizes the free ions that would disturb

powder deposition on the object in situation

of bad earthing or high humidity.

One happy OptiFlex 2 B owner, Ross Hume,

owner and manager of Osbournes Ltd in

Auckland, says he now easily achieves the

high powder coating quality he demands.

Osbournes manufactures and installs com-

mercial ventilation louvres that are mostly

coated. “We decided to put our own

powder coating plant in, as we were very

unhappy with the quality of our outsourced

powder coating service,” he recalls.

When the Osbournes team compared

the two leading powder coating equip-

ment brands, and found out that most of

the large aluminium extruders used Gema

equipment, it decided to buy the Gema

Optiflex2 B powder coating unit for three

reasons. First, the build quality of the Gema

Opitflex 2 B unit was far superior; second,

it is simple to use despite its advanced fea-

tures; and third, the expertise and support

that WA Stroud gave the team at the time

and continues to give are excellent.

“I unreservedly recommend the Gema Op-

tiflex2 B powder coating equipment to

anyone thinking of upgrading or investing

in new equipment,” Mr Hume says.

MANAGEMENT 33


Frustrated with the success ratio of the

products, Mr Schukin has developed and

launched the Innovation Deck a new set of

playing cards for engineers and inventors.

It provides an effective "brain hack" that

helps product creators to quickly refocus on

the customer and generate a wide variety

of solutions, allowing the creators to avoid

spending months on developing a solution

that has no potential.

It is frighteningly challenging to create new

inventions and products. Very few awarded

patents actually find their way to realization

in the form of new products. And that's not

all: according to the US Department of Com-

merce, for those products that get through

the hurdles of development and manufac-

turing, and are launched to the market, over

90 percent will fail in the first four years.

Why is it so difficult to create commercially

viable products? According to Mr Schukin,

our brains are to blame.

"Our brains are built up in such a way that

we delete most of the information that

comes our way," he says. "We're deletion

machines. For example, if right now you are

focused on reading an article online, you

are likely to delete most of the information

around you. You might not notice the noise

of the computer fan, or how warm your feet

may feel, until I mention it."

He says that a similar thing happens when

we develop products: once we get a prod-

uct idea that we believe in, we focus on it.

And as we put our idea into the spotlight,

we tend to delete everything else. We are

so laser-focused on developing our solution,

we ignore the inputs from the market and

whether there is a better way to add value

to the customer.

Mr Schukin mentions we should conscious-

ly look for ways to stop for a minute and

re-evaluate customers' problems and the

possible solutions available to us. "Those

who are able to control their focus, create

products that sell," he says.

After working with many small and large

businesses on product development, and

seeing people miss crucial customer inputs,

he decided to create the Innovation Deck.

These playing cards, designed for engineers

and inventors, contain a set of novel ques-

tions and techniques that allow us to easily

and quickly identify improvement opportu-

nities for a product, generate a wide range

of innovative ideas and choose an optimal

solution.

The Innovation Deck has just been launched

as a crowdfunding project on IndieGoGo

NATIONAL MAINTENANCE ENGINEERING CONFERENCE 35


As a dedicated bearing and power trans-

mission service company, Hamilton-based

Waikato Bearings’ experienced staff listen,

take a proactive approach when determin-

ing the best course of action required, solve

maintenance problems and do whatever it

takes to get plants operating again when

breakdowns occur.

As an SKF distributor, we stock all types of

rolling bearings, seals, drive belts, chains,

sprockets, couplings and lubrication sys-

tems. We will also locate components and

keep you informed at all times.

Technology enables infinite options when

developing a structured maintenance pro-

gramme. How critical a machine is in the

production cycle and cost of downtime,

determines how maintenance will be

managed.

Understanding your plant, knowing what

bearings and parts are required and wheth-

er they are readily available. If not readily

available, should there be insurance stock

on site? Waikato Bearings can help you de-

velop an asset management database.

Lubrication is often overdone or neglected,

either way a bearing’s service life is com-

promised. Centralised lubrication systems

optimise lubricant use and machine perfor-

mance. We can work with you to develop a

sustainable lubrication programme.

Vesconite unlike bronze does not require

lubrication and operates in wet and dirty en-

vironments. Water acts as lubricant allowing

wet and dirty applications to be considered.

Talk to us about Vesconite and the potential

to reduce maintenance costs.

Please feel welcome to have a conversation

about what it is worth to your company to

deal with suppliers who are passionate. It is

in our interest to look after your interests.

Waikato Bearings Ltd, an authorised SKF distributor, is proud to be part of the 2014 National Maintenance Engineers Conference.

“This year’s conference is a step change,”

says Maintenance Engineering Society of

New Zealand (MESNZ) secretary and NMEC

event director Craig Carlyle. “It is definitely

bigger and better than whatever we have

done since 2003. It will be a real opportuni-

ty for maintenance engineers to renew their

ties with their peers in the industry.”

Three weeks before the conference dates,

attendee registration was at an all-time

high, with the number already exceeding

200, compared to last year’s 175. Attend-

ees represent maintenance engineers from

the dairy, meat, food and beverage, forest-

ry, health, quarries/mining, wood products,

pulp and paper, textiles, agricultural, pack-

aging, engineering, site maintenance and

manufacturing industries.

“We are observing a new trend in attend-

ee registration,” Mr Carlyle says. “We are

seeing a lot more companies that we have

not heard of before. There are fresh names

and faces, and companies who used to send

one staff before are now sending more of

their people.”

Presented by the Maintenance Engineering

Society of New Zealand (MESNZ), a technical

interest group of IPENZ, this year’s confer-

ence and its associated trade expo carries

the theme ‘Lifting the game of maintenance

engineering in NZ’.

“In line with our theme, New Zealand’s en-

gineering future will be very much enhanced

by the knowledge transfer and networking

that will happen during the annual confer-

ence,” Mr Carlyle adds.

Conference attendees who have booked

the site tour will be given a first-hand look

of some of the maintenance programmes

being implemented at the Genesis Energy

Huntly Power Plant. “It is not every day

that engineers can get access to a facility

like Genesis Energy’s power plant. We are

thankful to the management of Genesis for

this opportunity they granted us,” Mr Car-

lyle says.

The exhibitor list has also grown, repre-

senting engineering supplies, careers and

employment, hydraulics, pneumatics, bear-

ings, software, preventative maintenance,

condition monitoring, electric motors and

many more. This include CRC Industries New

Zealand, EagleBurgmann, Eurotec, Filtercorp

International, Hydraulink Fluid Connectors,

James Walker NZ, K2 Technology, Klinger,

machinemonitor NZ, Mainstream Engineer-

ing, MM Kembla NZ, SEW Eurodrive, SGS

New Zealand, SKF, Thorn Lighting (NZ),

Zumtobel Group, Vitech Reliability and Wai-

kato Bearings.

Mr Carlyle says the new venue, Kingsgate

Hotel Hamilton, gives the conference a

larger exhibition and conference area.

New topics and new expert speakers are

also in the line-up. Among the timely issues

that will be on the table is the new Health

and Safety Act and the associated regula-

tions and guidelines, and how they present

the greatest change to industry and mainte-

Step change for iconic Maintenance Engineering Conference

Conference attendance in 2014 is expected to be 20 percent more than last year’s

The much anticipated National Maintenance Engineering Conference (NMEC) has “NEW AND BETTER” marked all over it. Scheduled this November 12 and 13, 2014, the event has new attendees, new exhibitors, new speakers, new topics, as well as a new venue and new people on the organising committee.

nance engineers in the last 20 years.

Other topics include discussions on the tools

and systems to better manage and maintain

assets and case studies on material failure,

plant efficiency and reliability improvement

and inspections.

The recipient of the MESNZ Bill Buckley

Scholarship award will also be announced at

the conference.

The two day conference is preceded by a

public day featuring training opportunities

and a Public Trade Expo.

Apart from the annual conference, part of

MESNZ’s upskilling programme for main-

tenance engineers is a regular network

evening hosted by prominent industrial

That equipment is only as good as the component parts from which it is built, so when we worked with leading offshore specifiers to develop an isolated pipe hanger this philosophy was our starting point.

TICO S Machinery Mounting MaterialTICO S is a high performance machinery mounting material manufactured from a blend of carefully selected cork particles and polychloroprene / acrylonitrile elastomers. It matches today’s fast changing manufacturing environment, where ease of machine mounting and flexibility of plant layout are prime factors.

TICO High Stress MountingsTICO Hi-Duty pads and buffers take on the toughest tasks. They have the strength and resilience to cushion massive impacts, absorb fierce shock loads, and attenuate severe vibration from heavy plant.

TICO Sliding BearingsAllowable movements within a building structure can be accommodated by the range of TICO Resilient Seatings, but in some cases the movement required is much greater than those seatings are capable of accepting. TICO Sliding Bearings are the ideal answer to this problem, providing an economical load bearing sliding support with very low friction characteristics and virtually an unlimited degree of movement.

Mr Buckley’s award was presented on Octo-

ber 15 at a networking event hosted by his

Mt Wellington-based company Buckley Sys-

tems (BSL), which produces super magnets

for the global silicon chip industry.

The award was presented by Larry Wiechern.

Maintenance Society honours Bill BuckleyIconic Kiwi engineer Bill Buckley was made a patron of the Maintenance Engineering Society of New Zealand (MESNZ) in honour of his contribution to engineering and support for tradesmen.

“Bill is an engineer that reflects the princi-

ples of the 120-plus engineers present this

evening,” he says. “He is and always has

been a strong supporter of apprentice train-

ing, and takes the time to talk and inspire

young pre-trade apprentices. He is a pretty

special engineer and this has been shown by

the wide range of awards he has received

over the years.”

Mr Buckley, a public figure recognised for

his achievements in engineering, yachting

and motorsport, has long been a strong ad-

vocate for engineering and apprentices. He

won the 2012 Ernst & Young New Zealand

Entrepreneur of the Year award and was a

finalist in the 2012 World Entrepreneur of

the Year held in Monte Carlo. His list of

awards include a recognition in the 2013

New Year Honours List when he was made

a Companion of the NZ Order of Merit for

services to technology, business and mot-

orsport, as well as being inducted into the

Hi-Tech Hall of Fame in 2013 as New Zea-

land Hi-Tech Trust’s Flying Kiwi.

He was visibly pleased to be honoured by his

peers and spoke warmly of the rich history

of New Zealand engineering companies that

had formed his career.

A group of 120 attendees were treated to

a bonnet-up look at the Buckley Systems

plant as part of the networking evening.

The experienced group were amazed at

the size and scope of the operation which

machines, fabricates and assembles high

technology magnets for export around the

world. While the machining centres were

leading edge and fully utilised, evidence of

the Kiwi can-do innovative attitude pervad-

ed the BSL facility.

BSL chief operating officer Mark Stolten

says it was a privilege to host the MESNZ

networking event. “Our staff enjoyed the

evening and it ended up a great team build-

ing exercise for us,” he says. “Thank you for

the award to Bill…as we all know he is a

great man and has put New Zealand on the

global playground of business.”

The Maintenance Engineering Society is

active across New Zealand, providing op-

portunities for maintenance engineers and

manufacturing operations to network and

share innovations and experiences; both at

a national level at their annual conference

or at these regional events.

The final network evening for 2014 is

planned for SAFE group (Drury) in December.

About 120 attendees were treated to a bonnet-up look at the Buckley Systems plant as part of the MESNZ October networking evening

VANZ Conference 26th, 27th & 28th May 2015

Wairakei Resort Taupo New Zealand

New in 2015! One way or another everyone contributes to the lack of reliability of our assets and equipment,

therefore everyone should constantly strive to gain a greater understanding about reliability improvement

and condition monitoring techniques. Using a combination of informative “101” presentations and hands-on

sessions with industry experts, mechanical, electrical, apprentices, operators, supervisors and managers can

learn a great deal about the techniques that create a safer and more profitable workplace.

A Conference of Your Peers

Improving reliability and condition monitoring are vitally important to all

forms of industry, and the practicing engineers, analysts, and technicians are

a special breed of people. But where do you turn to for support? Where can

you meet like-minded people to share your frustrations and triumphs? The

VANZ annual conference, in its 26th year, is your conference.

It is not another talk-fest with the same presentations as the previous years;

VANZ has adapted to meet your needs to include round-table discussions,

hands-on learning sessions, mini-practitioner “war stories”, and social events

where you can have informal discussions with your peers. And yes, there will

be technical presentations from local and international speakers to provide

opportunities to increase your knowledge and reinforce what you have

previously been taught.

Call for Papers VANZ 2105

One of the unique features of VANZ is that the speakers are chosen on their

merits; not according to their sponsorship fees. But we need to hear from

you. Have you been involved in a process that had a positive outcome – a

diagnosis that lead to corrective action that solved a problem? Come along

and tell the story. Or what about a process that did not end well? Was there

an important lesson learned? Come along and tell your story! Remember,

presentations don’t have to be about the toughest diagnosis that stumped

the experts, or involve unique pieces of equipment; they need to be about

real-life challenges that others can learn from. And they don’t need to be 45

minute dissertations; just a 15 minute story is fine too. And don’t worry

about being heckled by the attendees; you are among friends. Please contact

James Neale to learn more [we have a team of people available to support

and encourage all presenters].
