Energy-saving and environment-friendly injection molding machine represents the development direction of plastic machine

In the cost structure of injection molding products, the traditional Injection Molding Machine oil pump motor consumes 80% to 90% of the total equipment power consumption, accounting for a considerable proportion of the cost of injection molding products. The energy-saving and environment-friendly injection molding machine represents the development direction of the plastic machine. Whoever takes the first step, whoever must seize the market opportunity. It is precisely to see this that more and more manufacturers are placing energy-saving research and development in an important position.

The energy-saving technology of injection molding machine mainly includes three aspects: energy-saving injection molding technology; energy-saving actuator; energy-saving power drive system, the most important energy consumption of injection molding machine is power drive system.Plastic Blowing Machine

Compared with the traditional domestic driving method, the three-phase permanent magnet synchronous motor is replaced by a three-phase permanent magnet servo motor. The fuzzy matching method is used to realize the coordinated matching control of the servo motor and the variable pump.Precision Core Parts.

The total power loss of the servo pump controlled injection molding system is mainly composed of two parts:

1) Power loss of the motor, which mainly includes copper loss, iron loss and mechanical loss of the motor. This part of the loss is generally unavoidable, and only high-performance motors can be used to reduce losses.Household Plastic Mold.

2) Power loss of the hydraulic system. Thanks to the servo motor plus variable pump control system. This loss does not include throttling losses and overflow losses, but only volume loss and mechanical transmission losses due to leakage of the hydraulic system. Therefore, the total power loss of such a system is small and has a good energy saving effect.Plastic Spoon Machine.
