How can the injection molding machine save energy and reduce consumption?
The energy savings of an injection molding machine can be divided into two parts: one is the power section and the other part is the heating section.
Power Savings: Most inverters are used. The energy saving method is to save the residual power of the engine. For example, the actual power of the motor is 50 Hz, and you only need 30 Hz in production to produce enough, and the excessive power consumption is in vain. Waste, the inverter must change the output power of the engine to save energy.
Energy saving in the heating section: The most energy saving in heating is the energy saved by electromagnetic heating, and the energy saving rate is about 30% to 70% of the old resistance ring.
1. Compared with the resistance heating, the electromagnetic heating element has an additional insulating layer, and the heat utilization is increased.
2. Compared with the resistance heating, the electromagnetic heater acts directly on the material pipe to reduce heat loss through heat transfer.
3. Compared to resistance heating, the heating rate of the electromagnetic heating is faster than a quarter, which reduces the heating time.
Compared with the resistance heating, the heating speed of the electromagnetic heater is high, the production efficiency is improved, and the engine is in a saturated state, which reduces the power loss caused by high performance and low demand.
The above four points are the reason why flying electromagnetic heaters can save up to 30% -70% on injection molding machines.
