What is Overmolding?
Overmolding is an advanced plastic injection molding process in which one material is molded over another substrate to create a single integrated component. Unlike conventional molding, overmolding combines the strength of rigid engineering plastics with the flexibility of elastomers such as TPE, TPU, TPV or Silicone, resulting in products that offer superior grip, enhanced sealing, vibration damping and improved aesthetics.
The process begins by manufacturing a rigid base component using materials such as ABS, Polycarbonate, Nylon, Glass Filled Nylon or PEEK. This substrate is then transferred into a second mold cavity where a softer material is injected over selected areas, permanently bonding the two materials without adhesives or secondary assembly.
At Manufyn, our engineering team assists customers throughout the complete development cycle—from Design for Manufacturing (DFM), material selection and mold development to prototype validation and mass production. Whether you require low-volume prototype parts or high-volume production, our manufacturing partners deliver consistent quality for global OEMs.
