Insert Molding

Insert Molding is a unique process whereby a variety of components (die cast, screw machine, stamped metal, filter media, and other plastics) can be incorporated into plastic. Various features can be created in plastic around these components, such as fasteners, housings, insulators, connectors, etc.

This process is used extensively in the industry because it can take advantage of incorporating many and sometimes all of the features mentioned into one assembly. By taking advantage of the plastics unique design, many manufacturing steps can be eliminated.

This process is typically done using Vertical clamp injection molding machines. The reason for vertical opening and closing of the mold halves is that gravity works with you in keeping components in location  Items are positioned in the mold, the mold is held closed and molten plastic is forced in the mold and around the components that are in place. After the parts have cooled, the mold halves are separated and the parts are ejected.
