1. What Is Plastic Overmolding?

Plastic overmolding belongs to one type of injection molding. It uses the combination of two or more two kinds of thermoplastics to produce a single part or product. There are two main parts: the basis layer and the additional layer. The basis layer should be molded first and then the additional layer would mold on the surface of the basic layer.

After processing, these combined plastics will never depart from each other. It means that we do not need any primer or binder to achieve the eternal combination.
