Since we are an experienced machine builder, many times we will build an assembly or plastic welding machine to provide an efficient production environment.

What is Injection Molding
A manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial engineer.

What is Insert Molding
Insert molding is a highly efficient process by which metal stampings, bushings, electronic parts, and other discrete parts are combined into a single component through the injection of thermoplastic around the carefully placed parts. This can eliminate post assembly labor and form and integral part of your design.

What is Over Molding
Over molding is a process very similar to insert molding except it involves plastic over plastic instead of plastic over metal. Overmolding involves it’s own set of issues to obtain the proper shutoff’s that plastic (as opposed to metal) presents. We have a great deal of experience in overmolding dissimilar materials. In several cases, thermoplastic rubbers have been overmolded to give “soft touch” or other desired mechanical properties.
