Insert Molding

Our original insert molding planning service evaluates how prepared metal or rigid components can be held in place as a plastic part is molded around them.

Review insert geometry, locator access, resin flow, the required holding force, and any later assembly operations before the tooling approach is selected.

Insert Molding Capabilities

Insert molding can consolidate a prepared component and molded polymer into one intentional assembly. Use it where a retained insert, threaded feature, or reinforced interface needs to be held by the molded form.

What is Insert Molding?

The molding tool holds an insert in a controlled location while resin forms around it. Compared with post-mold installation, this can consolidate the part and hardware into a single purpose-built molded assembly.
