Overmoulding is a method of plastic injection moulding that moulds one component over another. It is often used to make tools easier to grip and use, improve resistance against water, heat, or impact and to give a more attractive appearance. How does it work? A base component or substrate is injection moulded, allowed to cure, then a second layer is moulded on top of the first to produce a single part. What applications use overmoulding?
