The Zwick Roell Group over a hundred years' materials testingexperience

Mechanical testing is the oldest branch of materialstesting and one which has continued to gain inimportance. As early as the 15th and 16th centuries,Leonardo da Vinci and Galileo Galilei were consideringmatters such as the bending load and elastic propertiesof materials. The first such testing machines appeared inFrance in the middle of the 18th century.

The Swiss, later German company Amsler began materi-als testing in the mid-19th century, followed by Roell &Korthaus in 1920, while mechanical-testing specialistsZwick had been making hardness testers and materialstesting machines and systems since 1937. In July 2001the group was reorganized as a corporation under thename of Zwick Roell AG, which today includes Zwick,Toni Technik, Indentec Ltd and Acmel Labo.

Zwick Roell AG's expertise in the field of force andextension measurement was reinforced by the acquis-ition in 2006 of the Austrian company Mephysik,followed by the German firm GTM in 2007. Together,these companies provide a comprehensive, co-ordinated component and function-testing programme from manually operated or fully automated hardnesstesters to static and dynamic integrated laboratorytesting systems for process-parallel applications.

Zwick's comprehensive and innovative hardnesstesting solutions

The success of our hardness testing machines andinstruments is founded on many years' experience, onour role as a global supplier and on maintaining closecontactwith our customers. The versatility and highlevelof 'intelligence' of our testing systems are theproduct of up-to-date engineering, powerful electronicsand application-orientated software.

But the Zwick Roell Group is far more than just asupplier of testing equipment, having receivedEN ISO 9001 certification as long ago as 1994 aguarantee of product and service quality.

Innovative hardness testing

Zwick has been supplying stationary hardness testingdevices for all standardized methods for many years,plus a wide range of portable hardness testers. Throughour active involvement in national and internationalstandards committees we are helping to shape modern,innovative hardness testing for both today andtomorrow.

A policy of innovative development has seen ourhardness product range greatly expanded, particularly inthe last few years. The Zwick Roell Group has probablythe most comprehensive selection of hardness testingmachines and instruments available for almost anysituation.

Stationary hardness testing machines andinstruments for the following methods: HV Vickers HB Brinell HK Knoop HM Martens (instrumented indentation

testing,formerly HU universal hardness) HR Rockwell (scales A...K, N, T) H ball indentation hardness HVT modified Vickers method HBT modified Brinell method testing hardness of special materials, e.g. carbon-

based materials, carbon brushes, plaster, asphalt;hardness of resilient floor coverings

Portable hardness testers for the following methods: Shore, IRHD HL Leeb HB Brinell HR Rockwell

Zwick solutions - customer benefitsZwick offers a complete range of hardness-testingmachines and instruments, from fully automated systemsto basic instruments for standard applications. Ourhardness testing machines use innovative technologiesfrom our materials testing range in conjunction withhardness testing add-ons and Zwick's testXpert

software.

Flexibility and upgradability, particularly with the zwicki-Line test frame, allow tailor-made, customer-orientedsolutions using: hardness testing devices for optical testing hardness measuring head for indentation

depthmeasuring

combination of hardness measuring head with a high-precision measuring microscope, giving hardnesstesting with optical indentation measurement anddigital depth measurement

compound tables with manual or motorised control application-orientated master and standard testing

programs in testXpert

Features of our hardness testing machines: modular design allowing flexible combinations virtually unlimited upgradability and expandability can be automated and integrated into automatic

testing systems state-of-the-art digital measuring and control

technology as standard used in production control, quality assurance and

research and development your guarantee of a secure, future proof investment

Hardness testers a broad spectrum of uses: standardised applications with line display and integrated standardized

conversion functions to other hardness scales forstandard applications

with touchscreen, extended functions and comfortableoperation for a wide range of testing assignments,including batch testing and production control

Our hardness testers are characterized by: straight forward operation automatic test cycle manual or automatic load changing flexible/large test area height high precision robust construction with play-free ball-bearing lead

screw a wide range of accessories
