About plastic mold injection molding

Injection molding is a manufacturing process for producing parts by injecting molten material into a mold. The mold is a cavity formed in a metal block, which is filled with a liquid plastic. The liquid plastic is then forced into a mold cavity under pressure, where it cools and hardens to form a part of the finished product.

Injection molding is used to produce a wide variety of parts, from small components to entire products. The process can be used to produce a wide range of materials, including metals, plastics, and composites. Injection molding is often used to produce complex parts with a high degree of accuracy and precision.

 

The process of injection molding consists of the following steps:

1. The mold cavity is preheated to a temperature slightly above the melting point of the plastic.

2. The molten plastic is injected into the mold cavity under pressure.

3. The molten plastic fills the mold cavity, and the excess plastic is forced out of the mold.

4. The plastic cools and hardens in the mold cavity.

5. The finished product is ejected from the mold.
