Insert molding is the process of placing a metal substrate into a mold cavity and encapsulating the metal insert with either plastic or rubber. Insert molding can be performed in a standard horizontal injection molding press, but loading and retaining the insert in the mold is critical and creates restrictions on part design.

ST has around twenty years of experience insert molding using both standard horizontal injection molding machines and vertical injection molding machines. Colson’s experience in mold design and processing applies to both rubber and plastic materials.

Colson engineering’s experience with mold design and material properties can be used to design and develop a new product or can help solve current product design problems.
