Overmolding Products

Over Molding is the process where one material is precision molded over another material, usually rubber (TPE) over plastic, for visual or ergonomic appeal. Very often when the design requires ” soft touch” or waterproofing (IP68), over molding is the manufacturing process that we will use. For over molding success, knowledge of material compatibility is crucial. Our extensive expertise in this field helps assure your end part will have the strong end-application bond and performance that your product success demands.

Insert molding can also be combined with over molding using parts made of aluminum, brass, stainless steel, copper, plastic and more.

International Protection Rating IP-68

IP-68 is the most rigorous Ingress Protection classification for water and dust protection. IP68 means that a product has been tested in a certified lab where it has proven to provide full protection against long-term submersion under water.
