HWA CHIN HC SERIES HC-80SE~HC-3200SE

1. It has the same features with all-electric machine that there is power consumption with machine running.
Power supplies for machine action only without extra power waste so it absolutely reaches energy saving target.
Hybrid servo system saves energy up to 40% than variable pump and up to 60% than fixed pump system.
2. Available high toque output hydraulic system pump driving with encoders of pressure and RPM feedback running through the operation sequences fully close looped.
3. There is fast response with less than 0.1 second and high repetition precision & linearity less than 0.1%.
4. Alternative air cool hydraulic radiator used for model less and including HC-350SE.
5. Hybridizing and uniting hydraulic-mechanism-electric into mono driving system creating and performing unique stable precision of system pressure close loop control.
The system reimbursing feature absolute away hydraulic driving varieties from the temperature factor.
Hydraulic flow close loop control actuating desired machine functions through RPM controlled pump system and limited the hydraulic surge supplying during low speed functioning.
6. Saving Energy & Low Noise Fixed rotation speed output in accordance with actual flow requirement. Very low energy consumption while machine idles.
Power saving is obvious without vain work. Oil temperature is not getting up and parts life become longer.

FOUR CYLINDER INJECTION MACHANISM (Optional)
Special design for extra high injection pressure

  1. Provide extra high injection pressure up to 1.3 times that of a double cylinder structure.
  2. Excellent for molding varied products.
  3. Double hydraulic pump gives flexible output for power savings.

HIGH EFFICIENT AND ACCURACY CLOSED LOOP ON INJECTION UNIT (Optional)

  1. Fits for extra thick and extra precise product.
  2. Closed loop control system with accumulator completes high precision and stable operation while injecting at  very high speed.
  3. Accumulator with four-cylinder injection decreases the resistance of oil return in order to increase injecting speed.

HIGH ANTI-CORROSION AND ANTI-WEAR BIMETALLIC BARREL (Optional)

  1. Bimetallic barrel suits the materials with properties of corrosion and wear.
  2. It extends the operation life of the barrels.

STRUCTURE OF MOLD FIXING

  1. O slack increases the strength of platen instead of T slack easy to fix mold and protect slack from damage .( Below HC-450)

BUILT-IN CIRCULATING LUBRICATION SYSTEM OF TOGGLE

  1. Free outside piping and easy to be maintained.
  2. Surplus lubricator is recycled with efficiency.
  3. Terminal sensor can assure of full lubricator in lubricating circuit.

QUALITY PROVEN CONTROL CIRCUIT

  1. Adapts microcomputer control system for special purpose provides accuracy and stability.
  2. Great memory capacity up to 120 sets of molding data.
  3. PID temperature control module assures maximum stability and accuracy.
  4. Equipped with position transducers precisely satisfy various requirements.
  5. Can be expanded online function with a personal computer in order to reach the management of injection molding data for each machine.

EXCLUSIVE LUBRICATION FREE SLIDEWAY

  1. The specially designed slideways provide added rigidity and smooth motion for injection unit.
  2. Slideway is free of lubrication for convenience.

SUPPERIOR TOGGLE MECHANISM

  1. Box type of movable platen decreases deformation and enhances product quality remarkably.
  2. Front fitted clamping cylinder which has shortened machine length significantly.
  3. Superior outward bending toggle for stable mold opening and closing with fast speed and bigger opening stroke.

ADJUSTABLE HYDRAULIC BUFFER DEVICE OF MOVABLE PLATEN

  1. The weight of mold and movable platen can be distributed over the hydraulic buffer device. It extends machine life.
  2. Wear of buffer device dose not influence the precision of machines.

SEMICIRCLE STRUCTURE OF TOGGLE

  1. Coaxial machining on those platen, holes of toggle pin and tie bar conducting increase great precision.
  2. Toggle pins are fixed by screws. It makes assembly easier and faster.
