OVER MOLDING

MIC provides a number of specialized plastic injection molding services, including over molding, which is the process of combining two or more molded plastic or elastomer parts to make a single finished product. In the process, the base layer part is molded then the additional plastic layer(s) are molded over and around the original part.

Overmolding is a very difficult process, requiring adherence to the very tightest of tolerances. The general concept is quite similar to insert molding, but has more opportunity for mistake and a much smaller margin of error. MIC’s overmolding processes create parts specifications as tight as 0.001”. We utilize high-tech injection molding equipment for our services for the highest possible quality and superb repeatability.

Because the materials we use shrink as they cool following the molding process, special consideration must be made in the creation of our molds. And, as MIC uses a number of different materials in overmolding, all of which have different cooling/shrinking properties, it is crucial that we create our molds to match the specific properties of the material(s) being used. Our mold designers will perfectly match their mold specs to the unique needs of your overmold project.
