Insert Molding

Insert molding is a process in which a prefabricated part is loaded into a mold for the plastic part to form around. The result is a stronger bond than can be attained through most other methods. Inserts can be made of any material capable of withstanding the plastic injection molding process.

There are a variety of potential benefits to insert molding that can make it an ideal choice for certain parts. Sometimes you need a great deal more strength and durability at a particular point on a part, maybe you require threaded fasteners that lock in more securely than plastic threads, or perhaps your part is a piece of an electronic assembly and requires a conductive path. Often times, assembly by hand can be simplified or avoided altogether by taking advantage of insert molding, yielding a more robust assembly at a lower cost.
