Insert Molding is yet another part of the “Total Plastic Solutions” offered by JG Plastics. Insert Molding is a special injection molding process where thermoplastic or thermoset materials are molded around another component, typically a metal insert, contact or tube. Material injected into the cavity captures exposed features of the inserted component creating an integrated assembly with a strong mechanical bond. This process is used extensively in electrical connector molding applications.

JG Plastics has over 40 years of insert molding experience. We understand the complexities of the insert molding, and the important role that proper part design plays in the overall molding process. Detailed mold design and construction are extremely important to maintain exacting part tolerances and tooling reliability. By using the proper injection molding material and processing parameters, we are able to mold many different types of inserts successfully.

We insert mold threaded inserts, medical instrument tubes and shafts, and a wide variety of electronic and electrical connector contact and connector shells.

Another form of insert molding is Film Insert Molding or IMD (In Mold Decorating). This is a process where a decorated or printed film is cut, formed and inserted into the mold cavity prior to mold closure. Thermoplastic resin is then injected against the film, forming a beautifully decorated part that is both durable and cost effective. Proper mold design and the use of the correct film and base resin are extremely important to the success of the Film Insert Molding or IMD process.

Film Insert Molding is used in the following industries:
