Design & Bond Review
We review geometry, undercuts, and bonding areas to ensure stable adhesion and clean finish.
Over molding combines two materials into a single component to improve grip, sealing, comfort, and aesthetics. It’s commonly used to add a soft-touch layer over a rigid plastic substrate or to integrate functional surfaces that would otherwise require extra parts and assembly.
Parts that benefit from soft-touch surfaces, sealing, or improved ergonomics.

Tooling planning and sampling to validate material flow, bond strength, and cosmetic appearance.
Over molding helps reduce assembly steps and improves product feel and function. It can also add sealing or protective features without extra gaskets, adhesives, or secondary operations.
Material pairing and finishing options to match performance and appearance goals.
Better ergonomics, integrated function, and a premium look without extra assembly.
Over molding is a multi-material injection process where one material — often a soft thermoplastic elastomer — is molded over a rigid plastic or metal substrate to add grips, seals or improved ergonomics.
Over molding is ideal for soft-touch handles and grips, sealing and gasketing, vibration damping, and combining materials for better function and comfort in a single part.
Rollex over molds common engineering plastics with TPE/TPU soft-touch materials and advises on material compatibility for strong bonding.
