Plastic Injection Molding process:

The injection molding process refers to the process of making semi-finished parts of a certain shape by pressing, injecting, cooling, and removing molten raw materials. The injection molding process of plastic parts mainly includes 6 stages mold clamping - filling - (gas-assisted, water-assisted) pressure holding - cooling - mold opening - demoulding.

The filling is the first step in the entire injection molding cycle, from the time the mold is closed and the injection is started until the mold cavity is filled to approximately 95%. In theory, the shorter the filling time, the higher the molding efficiency; but in actual production, the molding time (or injection speed) is subject to many conditions.

The function of the packing stage is to continuously apply pressure to compact the melt and increase the density of the plastic (densification) to compensate for the shrinkage behavior of the plastic. During the pressure holding process, the back pressure is high because the mold cavity is already filled with plastic. In the process of holding pressure and compaction, the screw of the injection molding machine can only move forward slowly and slightly, and the flow speed of the plastic is also relatively slow. The flow at this time is called holding pressure flow.

In injection molding molds, the design of the cooling system is very important. This is because the molded plastic product can only be cooled and solidified to a certain rigidity, and the plastic product can be prevented from being deformed by an external force after demolding. Since the cooling time accounts for about 70%~80% of the entire molding cycle, a well-designed cooling system can greatly shorten the molding time, improve injection productivity, and reduce costs.

Demoulding is the last link in an injection molding cycle. Although the product has been cold-set, demoulding still has a very important impact on the quality of the product. The improper demolding method may cause uneven stress on the product during demoulding, and cause defects such as product deformation during ejection. There are two main ways of demoulding: ejector demoulding and stripping plate demoulding.
