What is Custom Overmolding Process

Overmolding process is a manufacturing process in which a material is molded onto another material or substrate to create a single integrated part. This process involves using a second material, typically a thermoplastic elastomer (TPE), to cover and bond with a pre-formed part, such as a plastic or metal component.
The overmolding process can provide several benefits, including improved grip, cushioning, and durability. Overmolding is often used in the production of consumer goods such as toothbrushes, power tools, and electronic devices.
Overmolding can also be used to create multi-material parts with different properties, such as rigid and flexible areas within the same part. This process can be achieved through various methods, including injection molding, insert molding, and two-shot molding

Overmolding Process Applications

Overmolding is a plastic injection molding process in which a second material is molded over a substrate material to create a finished product with improved functionality, aesthetics, or durability. Here are some of the common applications of over-molding:

Soft Grip Handles

Overmolding can be used to create soft grip handles for hand-held tools, sporting goods, and electronic devices. The soft material provides a comfortable and slip-resistant grip, while the substrate material provides structural support.
