HWA CHIN HC SERIES HC-80~HC-3200

1. Microcomputer controller provides accuracy, precision, stability and fast reaction. System memory can store up to 120 sets of molding parameters. Auto diagnostic monitor system can detect malfunction immediately to shorter the troubleshooting time.
2. Microcomputer control system provide 4-step injection control with adjustable pressure/speed and 3-step holding pressure to meet most complicated molding requirements.
3. Full-automatic mold thickness adjustment provides easy and accuracy operation.
4. Special toggle design of the toggle has smooth and stable movement. Low-pressure protection device is utilized to prevent unintended damage of the mold. Toggle pins equipped with alloy bushings and auto lubrication device provide excellent lubrication efficiency and extend the machine life.
5. Shorter machines make the room can be used with good flexibility. The toggle mechanism has much longer clamping stroke than traditional toggle machines.
6. Lumped hydraulic circuit reduces power resumption and noise. Exposed hydraulic circuit makes maintenance easier.
7. High L/D rate enhances the mixing of thermoplastic. Optional four-cylinder injection increases injection pressure.
8. Depending on customers’ requirements, dual circuit system, closed loop on injection unit, accumulator and remote computer controlled are on requested.
9. HWA CHIN machine parts are machined by imported Japanese machining equipment, and rigorously inspected by 3D measuring device to ensure superior quality and accuracy.
10. Through 30 years of improvements and upgrade, specification, construction strength and functions absolutely satisfy customers’ requirement.

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 fiitted 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.

BUILT-IN LUBRICATION APERTURES

  1. Free outside piping and easy to be maintained.

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.

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

  1. Provides 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 EFFICIENCY HYDRAULIC SYSTEM

  1. Top quality hydraulic parts in the hydraulic system make the machine ideal for long time continuous operations.
  2. High efficiency hydraulic circuit provides stable motions and quiet running, while greatly reducing power consumption.

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