Plastic injection overmolding is a plastic injection molding process in which two or more materials are combined to produce a single final part. TPE is the most common material that will be used in overmolding process, and the other material is typically a rigid plastic, the plastic substrate and TPE are always joined either though insert molding or multi-shot moulding.
One of the biggest advantages of overmolding is that it creates one whole assembly as plastic flows around individual parts, as opposed to bolting or gluing the separate parts together, this reduces secondary operation and labor costs, as a result, overmolding reduces part cost. In addition, overmolding process improves component reliability as it eliminates bonding step in the whole process, at the same time, part strength and structure is also improved, and it also enhances design flexibility as it allows for production of parts molded of multiple materials.
Now overmolding process is not only used in electronics, but also widely used as medical devices and instruments, parts with soft grip handles, knobs and window reveal moldings etc.
