Injection molding is an important step in the production of plastic products. It is widely used in many companies, but many things are involved in the injection molding process, and it is easy to cause some defects due to improper operation in this process, which affects product quality and processing progress.plastic injection molding, Therefore, when we are in the injection molding process, we should take good control and avoid the following situations.

1. Different color points

Impurities of different colors of plastic products are likely to be exposed on the surface of the product after production.

2. Gas wire

It means that the traces left by the gas on the surface of the product are different from the ground and present a shiny color.

3. Collapse

As the material shrinks, the entire surface of the product collapses.

4. Welding seams

During the molding process of the product, the hot melt material and the wiring formed afterwards are prone to appear, which can be seen with the naked eye and can be clearly touched by hand.

5. Lack of materials

The main reason is that after the product is produced, some parts are not full.
