Injection Unit

This unit is composed of plasticizing, material feeding, injection base, pre-plasticizing motor, whole forward-backward cylinder etc., thereinto, injection and mold moving is driven by oil cylinder, and the plasticizing will be realized by screw which is actuated by oil motor directly. Our machine's injection unit with the advantages as compact structure, reasonable composition, equal plasticizing, high injection press and high speed, very suitable for producing high quality products.

  • Two hydraulic cylinders actuate the injection movement perfectly.
  • Easy adjustable multi-step injection pressure and speed suitable for precision molding.
  • Nitrided screw for high plasticizing capacities and long service life.
  • Screw produced by high precision CNC thread grinder to achieve high Plasticizing capacity and even mixing.
  • High torque variable-speed hydraulic motor drive directly for screw movement.
  • Pressure gauge indicates injection pressure and system pressure timely.
  • Easy adjusted pressure and flow proportional valve increase reliability and sensitivity.
  • High quality Linear potentiometer for screw stroke control.
  • Converse-restrain ring equipped on injection nozzl
Clamping System

Injection unit is composed of mold clamping oil cylinder, mold adjusting device, frontal and rear mold platen, stretch bar, elbow jointed bar frame, moving platen, safety device, central hydraulic ejector etc.

  • Platen and toggle machined by CNC with large open stroke, high efficient and reliable movement.
  • Five-point double toggle mechanism.
  • Clamping force can be adjusted to suit the mold.
  • Storage type automatic grease lubrication system.
  • Low-pressure mold protection.
  • Adjustable ejection function(speed, position and delay time) for various molding conditions
  • Easy adjusted pressure and flow proportional valve increase reliability and sensitivity.
  • High quality Linear potentiometer for screw stroke control.
  • Adjustable speed for mold opening and closing
  • Self-lubrication bearings are optional
Control Unit

Our standard machine is for 380v/50hz/3phases, the operation power supply is 24v, also we can adjust according to the different power supply standard in different areas.

  • Use ¡° TECHMATION ¡± Micro-processor Controller.

  • All controls are located for easy access and operation.
  • Alarm display indicates errors during operation and provides comprehensive fault information.
  • English language display.
  • Clamping, injection and Ejection are positioned by high precision linear transducers.
  • High capacity memory to store more than 60 sets of all molding parameters including time, count pressure, speed, stroke, mould daylight and barrel temperature etc.
  • Date Lock Key to protect the data from unauthorized modification.
Hydraulic Unit

This unit is composed of direction valve, proportional pressure valve, proportional direction valve, overfall valve, unilateral valve & pump, and hydraulic motor etc, these components compose the electric-hydraulic proportional loading feedback circuit, which is with fast respond, reliable running, stable action, energy saving, easy to operate, easy to maintain and other characteristics.

  • Proportional hydraulic flow control system that is stable and saves energy.
  • Hydraulic oil overheating alarm and protection function.
  • Urgent stop button function.
  • All cylinders are adopted world famous brand
Safety Device

1) Mechanical safety device:
This device is import for protecting operator's and mold's safety , if do the mold opening action at a safety door opening condition, the mechanical safety stick will drop down automatically during its backward moving course, so, even if there is any problem on the electric or hydraulic circuit, the safety block will prevent the forward moving of the safety stick if there is the trial mold closing action, accordingly this will prevent the mold closing action to be finished.
2) Electric safety device:
A. Safe door position-limited switch

The position-limited switch can break off the mold-closing electric circuit, when the safe door open, if you turn on the switch, the electric circuit will be broken off, accordingly the mold-closing action will not be done. If open the safe door during mold closing course, the moving platen will be stopped immediately.

B. Urgent Stop button

Under the urgent condition, you can press the urgent stop button, the oil motor will be stopped, accordingly the machine will be stopped immediately.
