Energy-saving of plastic injection molding machine can be divided into two parts: one is the power part, one is the heating part.
Energy-saving part of the power: Most inverters are used, and the energy-saving method is to save the remaining energy of the motor.
Heating part of the energy: Most of the heating part of the energy-saving is the use of electromagnetic heaters, energy saving rate is about 30% -70% of the old resistor ring.
1. Compared with the resistance heating, the electromagnetic heater has a layer of insulation and the thermal energy utilization increases.
2. Compared with the resistance heating, the electromagnetic heater directly acts on the heating of the material tube, which reduces the loss of heat transfer heat energy.
3. Compared with the resistance heating, the heating rate of the electromagnetic heater is faster than a quarter, reducing the heating time.
4. Compared with the resistance heating, the heating speed of the electromagnetic heater is fast, and the production efficiency is improved, so that the motor is in saturation, which reduces the power loss caused by high power and low demand.
