Insert molding and overmolding are two of our specialties, techniques mastered by only the most detail-oriented plastic injection molders. In the case of insert molding, we place an object in the mold and inject plastic around the component to form a mechanical bond. In the case of elastomeric overmolding of hard plastic, the bond is also chemical in nature as an elastomer attaches with the substrate material. In this way, a gripping or sealing surface can be added to a structural design.
Due to the often extreme pressures involved, this process requires close attention and control to prevent defects that are costly to correct. Overmolding is a challenging type of manufacturing, but the results can improve functions and cosmetics of many products.Our capabilities are so well-known that we often receive leads from national material manufacturers. Examples of the items we insert or overmold include:
