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.
