Custom Plastic Overmolding Expertise

Yixing Plastics has many years of experience in custom plastic overmolding. Overmolding is a plastic injection molding process in which one thermoplastic material is molded over another material to form one part.

Using two separate plastic injection molds on the press, two materials are blended together during the overmolding process. This forms parts with unique visual or ergonomic appeal, commonly used for handles or knobs.

Plastic overmolding technology serves a wide range of aesthetic and functional purposes across industries such as Medical Devices, Appliances, Electronics, Consumer, Agricultural, and Automotive products.

Soft plastics like urethanes and thermoplastic elastomers (TPE), as well as hard plastics such as nylon and polycarbonate, can all be overmolded.

Custom plastic overmolding also protects and improves parts while reducing cost, labor, and materials.

Custom overmolded plastics provide competitive advantages in a wide range of applications, including:

• Medical devices and instruments
• Parts with soft grip handles
• Knobs for appliances, controls, and assemblies

With our many years of custom plastic overmolding experience, mold design and building, and focus on innovative solutions, Yixing Plastics partners with customers to produce overmolded plastic parts. We help reduce labor and assembly costs while improving quality, reliability, and product integrity.

Overmolded parts reduce the need for secondary operations such as sonic welding and assembling. Whether reengineering existing products or developing new ones, Yixing helps you save time and money.
