Overmolding Service

Get custom plastic parts molded with two materials or metal inserts.

Our overmolding process delivers custom prototypes and on-demand production parts in as little as 15 days. Using cost-efficient aluminum molds, we produce parts from a wide range of thermoplastic and liquid silicone rubber materials.

Overmolding is frequently used for:
● low-volume production
● bridge tooling
● pilot runs
● functional testing and prototyping

What is Overmolding?

Our overmolding process uses standard aluminum molds for substrate parts, resulting in slightly longer cycle times. This allows our molders to closely monitor fill pressure, cosmetic quality, and part integrity. Once the substrate parts are complete, they are manually placed into the overmold tooling. Each part is then overmolded with either thermoplastic or liquid silicone rubber.
