Four ways of energy saving for Injection moulding machine:

• V/F control AC drive (frequency converter) +asynchronous motor: without feedback system, low control precision, is out of type.
• Vector control AC drive (frequency changer) + asynchronous motor + current feedback: easy to install, cost-effective.
• Vector control AC drive (frequency changer) + synchronous motor + speed feedback + pressure feedback: fast system response, the high price, high maintenance costs.
• Vector control AC drive (frequency converter) + asynchronous motor + speed feedback + current feedback: the second and third approach combines the advantages of the system to respond quickly, cost-effective.

Servo concept:
For energy-saving of injection moulding machine, the servo is to realize a feedback control system dynamic response, high control accuracy.

Advantages of vector control drive cabinet:

• Based on the injection moulding machine with constant rate pump, using a vector control variable speed drive, increase the feedback control system can achieve significant energy saving, without replacing motors and pumps.
  Low cost, 70 percent lower than the synchronous servo, cost-effective.
• Energy saving rate as high as 25% to 70%, the saving rate depends mainly on mold process parameters, Relationship between the speed of the die process parameter (0~99%) and energy saving have the greatest.
  The lower speed, the higher energy saving rate.
• If the value of the speed of the mold is generally 0 to 30%, the energy saving rate can reach 70%; if the injecting speed and melting speed values generally above 90%, and without cooling time (Opening mold right away after melting), the saving rate can only reach about 25%.
• If the vector control drive cabinet fails or needs maintenance, does not affect the injection molding machine to work properly.
• Low maintenance cost of injection molding machine.

V&T Technologies Co., Ltd. is also the reputed leader of energy efficiency retrofits of plastic injection moulding machines in the world, achieve 25% - 70% energy saving for injection moulding machines.
