2025 10 Leading Overmolding Factory in China

Introduction to Overmolding

Overmolding is a manufacturing process that involves molding one material over another. This technique combines two or more different materials, typically a rigid substrate and a softer, more flexible material, to create a single, integrated part. The process offers several advantages, such as improved grip, enhanced aesthetics, better protection for internal components, and the ability to combine different functions in one part. It is widely used in various industries, including automotive, consumer electronics, medical devices, and household appliances.
