Definition
Molding one polymer, usually an elastomer, onto another plastic part.
Our Expertise
We frequently use overmolding to bond an elastomer (synthetic rubber) to a rigid plastic substrate. This versatile technique can provide different benefits:
- GRIP: Elastomers provide a lot of traction to the hand and fingers, making a knob easier to turn, or a radio less likely to be dropped.
- IMPACT: Sheathing corners and delicate features in rubber can dramatically increase impact (drop) performance.
- APPEARANCE: The “second shot” is usually a different color than the substrate. The contrast and interplay of colors and textures provide a great tool for visual interest.
- SAFETY: Synthetic rubber typically won’t hold a static charge. Devices that might be used in a Hazardous Location can benefit from this property.
