Micropcomputer

The machine is controled by  TECHMATION microcomputer, which makes the work reliable and automatic in high level. The advantages are as follows:

1. Large LCD screen

2. Multi-language control interface: Chinese, English, Russian, Spanish, French, Arabic, etc.

3. Can save 100 sets of mould parameter.

4. Automatic alarm, can display problem location, easy for maintenance.

Screw

Using Screw for feeding raw material, allowing processing of various materials. Strong plasticizing ability, high injection speed. Using resistance heating coils to heat the barrel, adopting cold screw protecting device, the screw will not operate until the temperature reaches the setting value.

Safety Door

Adopts electrical and mechanical double safety device. The mould will not clamp when the door is open, which makes the production process safer and reliable.

Clamping Mechanism & Pull Rod 

5-point double-elbow clamping mechanism allows a high and stable clamping speed.

Pull rods are made of high-quality steel, chrome-plated, makes the service life longer.

Ejector Device

Multi-point hydraulic ejector device, can choose the suitable number of ejector rod according to the actual working needs. It makes the demolding more even

Mould Adjustment Device

Mould adjustment device is drive by hydraulic controlled gear transmission, which is easy for operation.

Electric Gauge

Imported travel switch or electronic gauge, makes the operation in higher precise.
