Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that makes thermoplastics or thermosetting plastics into various shapes of plastic products by using plastic molding mold. It can be divided into vertical type, horizontal type and all electric type. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it shoot out and fill the mold cavity.

The Joule effect of electric current is used to transform electric energy into heat energy to heat objects. It is usually divided into direct resistance heating and indirect resistance heating. The power supply voltage of the former is directly applied to the heated object. When there is current flowing through the heated object, the electric heating ironing machine of the heated object will generate heat.

The object that can be heated by direct resistance must be a conductor, but it must have a high resistivity. Because the heat is generated by the heated object itself, which belongs to internal heating, the thermal efficiency is very high.

Indirect resistance heating needs to be made of special alloy materials or non-metallic materials into heating elements, which generate heat energy and transmit it to the heated object by means of radiation, convection and conduction. As the heated object and heating element are divided into two parts, the types of heated objects are generally unlimited and easy to operate.
