The energy saving of the injection molding machine can be divided into two parts: one is the power part and the other is the heating part. Energy saving in the power part: Most of the inverters are used. The energy saving method is to save the residual energy of the motor. For example, the actual power of the motor is 50Hz , and you actually only need 30Hz in the production to be enough for production, and the excess energy consumption is in vain If it is wasted, the inverter is to change the power output of the motor to achieve energy saving effect. Energy saving in heating part: Most of the energy saving in heating part is the use of electromagnetic heaters , and the energy saving rate is about 30%-70% of the old resistance coil .
