The zipper machine is mainly composed of various hydraulic components and hydraulic auxiliary components, among which the oil pump and motor are the power sources of the injection molding machine. The electrical control system and hydraulic system are reasonably coordinated to achieve the process requirements (pressure, temperature, speed, time) and various program actions of the injection molding machine. Mainly composed of electrical appliances, electronic components, instruments, heaters, sensors, etc. There are generally four control methods, manual, semi-automatic, fully automatic, and adjustment.

The heating system of the zipper machine is used to heat the material barrel and injection nozzle. The material barrel of the injection molding machine generally uses an electric heating coil as the heating device, which is installed on the outside of the material barrel and is segmented and detected by a thermocouple. Heat conduction through the cylinder wall provides a heat source for material plasticization; The cooling system is mainly used to cool the oil temperature. Excessive oil temperature can cause various faults, so the oil temperature must be controlled. Another area that needs to be cooled is near the discharge port of the material pipe, to prevent the raw materials from melting at the discharge port, which may cause the raw materials to not be discharged normally.
