Overmolding is an injection molding process where one material is molded over another material or component to create a single finished part. The base part can be plastic, metal, or an insert, while the overmolded material is usually a soft plastic or rubber-like material such as TPE, TPU, or silicone.

This process is commonly used to improve grip, sealing, impact resistance, appearance, and product functionality. Overmolding is widely applied in electronic enclosures, handles, medical devices, automotive parts, power tools, and consumer products.

Overmolding helps improve both product performance and manufacturing efficiency. It can enhance product appearance, improve grip and comfort, provide better protection, and reduce assembly costs by combining multiple materials or components into one finished part.

1. Improved aesthetics with color, texture, and soft-touch surfaces

2.  Better functionality, such as grip, insulation, and shock absorption

3. Increased durability against impact, wear, moisture, and vibration

4.  Reduced assembly time and overall manufacturing cost
