What Is Plastic Injection Molding?

We see products in the shelf at supermarket, which come from the same factory with the same packaging. Manufacturers always want to use one to create more than one. Do you want a beautiful packaging with lower cost price for your products? Plastic injection molding can do it.

Brief Introduce of Plastic injection molding

Nowadays, Plastic injection molding is widely used in our daily life. Every plastic products we seeing, mostly made by Plastic injection molding.

Usually injection plastic molds have five parts to work. Nozzle, charge, runner, ejected pins and parts cavities. The main parts of them is parts cavities where can used in production. Every injection plastic mold take electric as their energy. As automatic design, it can be putted on the production line to create a mass-production.

The working process of Plastic injection molding is that molten material was putted into the charge, along the nozzle fully fill with runner and parts cavities. When the material cooled, the ejected pins putted the parts away from cavities. This is the complete process of Plastic injection molding.

Why We Choose Plastic injection molding
