Overmolding Strong Bonds

With overmolding, you can improve the functionality and look of your product while saving time and reducing costs.  Overmolding can also improve the strength of the part, creating a more reliable end-product.

What is Overmolding

Overmolding is the process of molding plastic onto plastic or metal components.  A part is engineered to fit into a steel mold to allow plastic to be formed around the part, creating a strong bond between the part and the overmolded plastic and eliminating the need for assembly.

Because your overmolded parts require extremely tight tolerances to fit like a glove, overmolding can be difficult to achieve. Our experienced engineering and tooling teams work with you to make sure your parts and tools are designed properly to account for shrink and other variables when overmolding.
