July 19, 2007 Overmolding Technology Over-Molding utilizes the injection molding process to apply one material [Over-Mold] onto another material [Substrate]. Multiple Material Molding Multiple Material Molding is also sometimes called multicolor or two-shot injection molding. Matching the surface energy on both materials is critical for building specific interactions between materials.

One angle is to offer chemical foaming agents that help reduce plastic material use. The products help reduce material use by up to 20% depending on part geometry and wall thickness. Processing conditions can cause material properties to shift from the values stated in the information.
