Company WOOJIN PLAIMM INTRODUCTION PRESENTATION 2014

Nothing is impossible to a willing to heart

Our main goal is manufacturing “Excellent Quality” injection molding machine since 1985 that we started to produce

plastic injection molding machine with empty hand.

Although we have to go long way to arrive, all our members are approaching step by step.

Nothing is impossible those who have settled a goal.

WOOJIN PLAIMM will not hesitate to challenge for

better serving our customers.

High Efficient and Low Noise (Internal Gear Pump) – NEW DHPC

(Dorninger Hybrid Drive Control)

New Energy Saving Proportional Valve

If the hydraulic pass through P-T Line △P decrease leak and it will minimize the lost of energy. It also have motion algorithm software, graphic proportion interface, and upgrade Closed Loop Control will control servo hybrid system so it will be more energy efficient.

Minimize lost of hydraulic pressure (△P)

-Hydraulic pipe is non weld simless pipe.

( rustless ,superb surface preparation so decrees frictional resistance and superb in high-pressure)

-Hydraulic block is made of nickel-plated so , it is rustless, flow rate and slip coefficient will decrees)

Improve Productivity

1) It is apply with optimize clamping toggle mechanism (Dry Cycle Time shorten 4.0sec → 2.0sec)

2) High-Speed open-close proportion vale will have high response time so it will decrease time of open-close (80ms)

3) Apply Injection Direct valve type will have high response time so it will decrease time(60ms)

4) In injection small pump junction, so it will be high injection(190~300mm/sec)

5) Optimize in close ejector and in charging open with possibility of complex movement.

6) For thin injection it can be use high speed injection. (1000mm/sec, 60ms, 0.1%)

→ Reduce injection cycle time (High Cycle) so it will improve productivity.

Improve Reproducibility

1) In proportion valve have automatic hydraulic graphic valve so the clamping control will improve in precision. (±0.5mm → ±0.1mm)

2) For back pressure closed loop it will use feedback control, so it will improve back pressure.

→ By improve precision control; it will improve injection and cost.

3) System Feature – Cooling and Filtering - cooling and Filtering

When forced one way internal circulation runs it will reduce friction of filter and cooler.

It does not need pump suction filter for internal circulation; it use only oil filter so it will improve cycle period and reduce noise.

5) Clamping unit part – New external toggle mechanism

Clamping unit part

Control part of clamping unit

Position accuracy of clamping control

is superb with electric geared motor

and encoder sensor.

It has less shock & less noise than

Hydraulic motor. (closed loop)

Less Friction

Less friction limited LM guide. I will have less

friction in both start and no moving stick slip.

(Increase response time)

Enable to have more longer clamping stroke and ejector stroke

than the outward type. Also, Surface pressure uniformity is

outstanding same as a direct pressure type with perfect center

press plate. (76%)

Clamping unit part

Newer design will give lower friction and

vibrate even in high speed in mold open and

close; it will give smoother movement and

reproducibility.

(Higher Speed)

Toggle pin and hydraulic

cylinder have coating so it will

have lesser friction and

overload.

(Clamping force within 0.2%)

Less Overload,

Optimization of toggle

velocity ratio

Existing toggle velocity ratio

New – Toggle Mechanism

In mold open and close movement step, transfer ratio of

cross-head and platen velocity maintain constantly as

possible. Otherwise existing toggle, in high speed open-

and-close acceleration gradient it will make low vibration

and smooth movement using by low angle gradient

movement sequence.

Proportional valve’s control accuracy will improve, one of

the essential feature for high-speed mold open and close.
