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 way is to save the motor energy consumption, such as the actual power of the motor is 50Hz, and you in the production of actually only need 30Hz enough production, those excess 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 energy saving is mostly the use of electromagnetic heaters energy-saving, energy-saving rate is about 30%-70% of the old resistance ring.
1. Compared to the resistance heating, electromagnetic heaters more than a layer of insulation, thermal efficiency increased.
2. Compared with the resistance heating, the electromagnetic heater directly acts on the material tube heating, reducing heat transfer thermal loss.
3. Compared with the resistance heating, the heating speed of the electromagnetic heater faster than one-fourth, reducing the heating time.
4. Compared with the resistance heating, the heating speed of the electromagnetic heater, production efficiency is increased, so that the motor is in saturation, so that it reduces the high power and low demand caused by power loss.
