Introduction
Overmolding is a versatile manufacturing technique that enhances product performance by combining different materials into a single component. This process is widely used in various industries, from automotive to medical devices, due to its ability to improve grip, durability, and aesthetics. In this article, we will explore the diverse applications of overmolding, while also discussing its relationship with die casting China.
What Is Overmolding?
Overmolding is a specialized injection molding process in which a secondary material is molded over a base material (substrate). This technique allows manufacturers to enhance product functionality by integrating multiple material properties into a single unit.
Types of Overmolding
- Plastic over plastic – Common in multi-layered consumer products.
- Rubber over plastic – Frequently used in tools and electronic casings.
- Rubber over metal – Provides grip and shock absorption in industrial applications.
- Plastic over metal – Improves insulation and corrosion resistance.
- Metal over plastic – Less common but used in specialized applications requiring reinforcement.
