What’s Overmolding Process?
Overmolding is an advanced injection molding process that revolutionizes product design and functionality by layering rubber-like TPE plastic over an existing substrate. This dynamic technique finds applications in a range of industries, from enhancing grip and dampening vibrations to improving sealing and comfort. The process begins with meticulous material selection, ensuring the TPE overmold and substrate compatibility. Factors like adhesion, hardness, and friction are considered to achieve optimal results. During injection, two primary methods are employed: manual and two-shot molding.
Manual molding involves injection molding the substrate and then hand-loading it into a separate mold for over-molding. Two-shot molding employs advanced machinery to mold the substrate and apply the overmold continuously. Overmolding yields numerous benefits, including improved grip, enhanced comfort, and extended product lifespan due to better shock absorption. The technique’s versatility enables the creation of products with unique shapes and textures, elevating both functionality and aesthetics. From ergonomic handles to electronics protection, overmolding’s impact is far-reaching, enhancing product quality across various sectors.
