What Is Overmolding in Injection Molding?
Overmolding is a sophisticated injection molding process that fuses two or more thermoplastic materials into a single, cohesive component. The procedure starts with molding a base layer known as the substrate, which serves as the foundation of the part. A secondary material—called the overmold—is then injected over or around the substrate, forming a durable, secure bond as the materials solidify. This technique enhances product performance, providing improved grip, aesthetics, and structural strength. Overmolding is widely used in industries like automotive, electronics, and medical devices where durable, multi-material parts are essential.
