Overmolding is a multi-step injection molding process where two or more components are molded over top of one another. One elastomer is molded onto a second rigid material, combining multiple materials into one part.

This technique is commonly used in consumer goods, automotive industry, medical industry, electrical industry, and beauty industry. We specialize in overmolding silicone, liquid silicone, and conductive silicone on plastic, metal, FPC, and magnet substrates.
