Overmould Component Tooling Two Shot Injection Mold
Overmolding is a two-step process in which individually molded parts are combined to enhance the functionality of the product. Generally, plastic parts are produced using plastic injection molding. After cooling, they are placed in an overmolding tool and then coated with molten thermoplastic or rubber. The process of insert molding is different because it involves encapsulating the product in molded plastic.
A variety of thermoplastic materials can be overmolded, including soft plastics such as urethane and thermoplastic elastomers (TPE) and hard plastics such as nylon and polycarbonate. Some common forms of overmolding are:
What Materials Commonly Used in Overmolding? Overmolding can be used with a wide range of materials, including:
The overmolding process can be used to add texture, color, or functions to a product. Because the parts are permanently joined together, overmolding eliminates the bonding step for improved component reliability. Device design is more and more about the ergonomics and aesthetics as well as the function. Overmolding is a great way to address both areas in a very reliable way.
