Overmolding involves injecting a secondary resin onto a partially completed component, combining them, and creating the final part. This process can be completed in a single injection cycle. This combination streamlines the manufacturing processes by reducing waste and optimizing material usage. It makes tools easier to grip and manipulate and can seal and waterproof sensitive components with a protective layer that increases durability. Overmolding is important for medical devices, outdoor/sports equipment, and handheld tools.
