INSERT MOLDED COMPONENTS

When a specific design requires combining multiple materials into one finished part, the cost-effective process known as insert molding may be the solution you need. With Insert molding, a plastic part is formed or molded directly over or around metal or plastic components, resulting in a single piece assembly. A typical example is a plastic handle molded over a metal screwdriver shaft. This value-added molding operation eliminates the need for a costly additional assembly process. The process was originally developed to place threaded inserts in molded parts, and to form the plug around the prongs on the ends of electrical cords. It was found that molding directly over the metal parts saves time and money by eliminating an assembly step. Today, there are few design limitations or restrictions on material combinations.
