The principle of operation of the plastic mold

[aminaas1576]

The plastic mold usually consists of a mold holder (fixed mold), a mold core (movable mold), an ejector, an ejector rod and other components. Its working principle is that the plastic material is heated and melted, injected into the mold, and then formed under the influence of pressure, temperature and other factors.


In the first stage, the plastic material is heated to a certain temperature so that it becomes molten and can be injected into the mold.
In the second stage, the plastic material in a molten state is injected into the mold.
In the third stage, we wait until the plastic material hardens and forms, and unload the finished product.

3. The process of making a plastic mold
The production of plastic mold can be cayman islands number data divided into three stages: mold design, mold processing and mold testing. Among them, mold design is one of the most important stages, it should fully consider the shape, size, thickness, structure and other factors of plastic products, according to the actual needs to design a suitable mold structure.

The mold processing stage requires the use of CNC equipment and various cutting tools. Generally, the mold processing precision is very high to ensure the good quality of the final plastic products.

The mold testing stage is to check the proper functioning of the mold, usually using plastic raw materials to test the mold to check whether the mold meets the actual production needs.
