Description

HX 428 hydraulic plastic injection press adopts the latest technology from home and abroad. In this machine, there are 13 ejectors, enabling high-efficient injection. Its clamping force is 4280 KN, and the mold clamp’s opening stroke is 780 mm. It is available for forming plastic products whose height is within 820 mm while above 300 mm. This machine is favorable due to high performance, stability and low cost. We are reputable injection moulding solution supplier as well as dedicated hydraulic plastic injection press manufacturer in China, if you are looking for more information, please feel free to contact us.

Advantages

1. Excellent Energy-Saving Performance

HX 428 hydraulic plastic injection press combines electrical and hydraulic driving technologies together so as to put out power according to actual load demands. In this way, unnecessary energy dissipation is avoided.

2. AC Servo Motor Driving Oil Pump Unit

After receiving the pressure and flow instruction from computer controller, the servo driver will compare it with the actual pressure and flow feedback, and rectify the difference by controlling the rotating speed of the servo motor. Thus, the control on hydraulic plastic injection press is not only accurate but also fast, and the repeatability of the products is high as well.
