Plastic Injection Moulding Machine.

Application and Features:

Applicable to injection molding of various kinds of thermoplastics, and have following features:
1. Adopting double-cylinder injection, with multilevel injection, pressure maintaining and anti-dribbling action, high injection pressure, and fast speed.

2. Low-speed high torque hydraulic motors drive screws directly, stepless speed changing is achieved.

3. Adopting five-pivot point double-elbow hydraulic machinery clamping devices, for energy saving and stable movement.

4. Adopting computer control, proportional electro-hydraulic drive,  fail safe, high degree of automation.

5. The machine has an electrical safety duplicate protection device, which is safe and reliable to be operated.

6. Hydraulic components are designed to be outside the machine, which is easy for installation and maintenance.
