The energy-saving of injection molding machine can be divided into two parts: one is the power part, the other is the heating part.
Power Part Energy Saving: Most of the use of inverter, energy-saving method is through the energy saving motor, such as the actual power of the motor is 50Hz, and you in the production actually only need 30Hz enough to produce, those extra energy consumption is wasted, inverter is to change the power output of the motor to achieve energy-saving effect.
Heating part of energy-saving: heating part of the energy saving is mostly the use of electromagnetic heaters energy saving, energy-saving rate is about 30%-70% of old-fashioned resistance.
1. Compared with the resistance heating, the electromagnetic heater has a layer of insulating layer, and the utilization of heat energy increases.
2. Compared with the resistance heating, the electromagnetic heater directly acts on the material tube heating, reducing heat transfer energy loss.
3. Compared with the resistance heating, the heating speed of the electromagnetic heater is more than One-fourth, and the heating time is reduced.
4. Compared with the resistance heating, the heating speed of the electromagnetic heater, the production efficiency is increased, so that the motor in saturation, so that it reduces the high power and low demand caused by power loss.
The above four points are flying such as electromagnetic heaters, why can the injection molding machine energy saving up to 30%-70% reasons.
