Composite Insert Molding Services

Composite insert molding combines plastic material with pre-existing inserts or other substrates during an injection molding process. The result is an integrated component rather than separate pieces assembled later. Midwest Molding, Inc. supports this work with project engineering, tooling assistance, dedicated equipment, and process optimization for automotive, electronics, and consumer goods applications.

The suitable insert depends on the component design, material compatibility, process requirements, and intended application. Midwest Molding, Inc. describes its insert and composite molding capabilities as combining materials through injection molding to create complex components. Project engineers can review the design, tooling needs, and production requirements to determine an appropriate approach.

Overmolding injects plastic over a pre-existing part, substrate, or insert to create a multi-component assembly. Insert molding is a broader integrated process that places an insert into the molding operation so it becomes part of the finished component. Midwest Molding, Inc. offers both capabilities with dedicated equipment and quality control systems.
