Injection molding machine Servo transformation 
 A variable pump injection molding machine is also energy-saving injection molding machine, but the saving rate is relatively low. 
 The main difference of the variable displacement pump with standard dosing pumps is different output power, variable pump output power varies with the load changes. Quantitative output of the pump power is relatively constant, variable pump output power is very low in the case of small flow of action, and the quantitative output of the pump power is almost constant. Due to the pump load characteristics, adopt servo technological transformation, the energy saving effect is very significant. In addition, the use of servo speed control technology greatly reduces the reactive power loss of the injection molding machine pump motor, motor power factor, reduce line losses, thereby improving the efficiency of the plant's power supply to achieve the purpose of energy saving.
