The injection molding machine is mainly composed of injection machine, mold, hydraulic system, electrical system, control system and other parts.

Injection machine is the most important part of the injection molding machine. It is mainly composed of hopper, screw, heater, nozzles and other parts. The role of the hopper is to store the plastic particles, which are melted by turning the heat on the screw.  The heater is mainly used to control the temperature of the screw, in order to make sure the plastic melted  completely. The nozzle part is to inject the melted plastic into the mold.

Mould is another important part of the injection molding machine. Its function is to inject melted plastic into the desired shape mould. After cooling and solidifying, we can obtain the desired parts. The shape and size of the mold determines the shape and size of the final product.

Hydraulic system consists mainly of oil cylinders, oil pumps, and electromagnetic valve components. Its effect is to realize the injection moulding machine and the injection moulding process by controlling the motion of the oil cylinder piston..The pump is responsible for the delivery of hydraulic oil to the hydraulic system, and the solenoid valve controls the direction of the flow of hydraulic oil.

Electrical system consists mainly of components such as motors, junction boxes, switches, fuses, and the effect of which is to inject the control system of the moulding machine through various actions..The electrical system, through the interface and the human-machine interaction interface, shows all the control parameters of the injection molding machine.

Control system is mainly composed of computer and PLC (programmable logic controller), its role is to control the action process of injection molding machine, and real-time feedback condition and parameters. Linkage control system, but also with other equipment, for automated production.
