Overmolding material compatibility: a quick guide
Overmolding, the process of molding one material over a substrate made from another material, is a highly useful form of multi-material plastic injection molding. By combining soft and hard materials, overmolding makes it possible to make durable tools with soft hand grips, industrial components with built-in seals, and parts with high-friction surfaces. However, before making parts with this process, it is vital to understand overmolding material compatibility. The best overmolded parts have a strong chemical…
