Frequently Asked Questions

What is custom overmolding?

Custom overmolding is a manufacturing process where one material is molded over another substrate to create a single integrated part. It is commonly used to improve grip, sealing, insulation, vibration control, durability, or appearance. For OEM products, overmolding can also reduce assembly steps by combining multiple functions into one component.
