Injection system composition: The injection system consists of a plasticizer and a power transmission device.

The plastic injection device of the screw injection molding machine is mainly composed of a feeding device, a feeding cylinder, a screw and an injection nozzle. The power transmission device includes an injection cylinder, an injection pedestal, and a screw drive (melt motor).

Injection system function

The injection system is one of the important components of the injection molding machine. There are three main forms: plunger, screw and pre-molded plunger injection. Currently the most widely used is the screw type. The function is that, on a circulating plastic injection machine, the plastic can be heated and plasticized in a predetermined time, and the plastic injection cavity is melted by the screw under a certain pressure and speed.

Clamping system

Clamping system function: The function of the clamping system is to ensure the mold clamping, mold opening and ejection. At the same time, after the mold is closed, the mold has sufficient clamping force to resist the pressure generated by the molten plastic entering the mold cavity, preventing the mold from being slit and causing the product to be in a bad state. The clamping system consists of: the clamping system is mainly composed of a clamping device, a mold adjustment mechanism, an ejection mechanism, a front and rear fixed template, a moving template, a clamping cylinder and a safety protection mechanism.

Hydraulic system

The function of the hydraulic transmission system is to provide power to the injection molding machine according to various actions required in the injection molding process to meet the pressure, speed and temperature requirements of the various components of the injection molding machine. It is mainly composed of various hydraulic components and hydraulic auxiliary components, wherein the oil pump and the motor are the power source of the injection molding machine. Various valves control oil pressure and flow to meet the requirements of the injection molding process.

Electrical control system

The electronic control system and the hydraulic system can be reasonably matched to realize the process requirements (pressure, temperature, speed, time) of the injection molding machine and various program actions. It is mainly composed of electrical appliances, electronic components, meters, heaters, sensors and the like. There are four control methods: manual, semi-automatic, automatic, and adjustment.
