Plastic Horizontal Injection Molding Machine For Plastic Toothbrush

Electricity is one of the biggest cost expenditures for injection moulding products besides raw materials. For most injection moulding machines, electric energy is first converted into kinetic energy through the motor, then into hydraulic energy through the oil pump, and then drives the various actions of injection moulding cycle to complete the injection moulding process. As we all know, the law of conservation of energy does not increase or decrease in the process of changing energy from one form to another, but in fact, energy loses in the process of conversion because of the "useless" output energy, such as heat energy, produced in the process of conversion. The essence of energy saving is to reduce the "useless" output energy.

Asynchronous Motor Quantitative Pump

Traditional injection moulding machine uses asynchronous motor (squirrel cage) to provide power. The constant speed asynchronous motor converts electric energy into kinetic energy. The output "useful" kinetic energy is only about 90% of the input electric energy (when full load), while the others become thermal energy. Therefore, the motor will bring its own fan to take away the heat energy.

On the one hand, the induction motor drives the quantitative pump to output constant flow; on the other hand, the flow requirements of each action in the injection cycle, such as opening and closing die, ejection and so on, are different, and the unnecessary flow will flow back to the tank under the set pressure at that time. The slower the action is, or the greater the set pressure is, the more energy will be wasted, and the waste energy will become heat energy, which will increase the oil temperature. Therefore, generally speaking, the farther the action speed is from the full speed, the longer the time is, and the greater the pressure is, the greater the potential energy-saving range is.
