Midwest Molding supports automotive, transportation, electronics, consumer goods, and appliance applications. Its programs center on complex molded components and assemblies, including insert-molded and overmolded components, wire harness assemblies, and new tooling guaranteed for the life of the program.

Yes. The company provides multi-component assembly and wire harness assembly alongside its injection molding capabilities. This can help customers coordinate molded parts and additional components through one manufacturing provider. Midwest Molding also lists sonic welding and vibration welding among its integrated manufacturing capabilities, supporting complete or ready-to-install assemblies.

Two-shot molding produces components with multiple materials or colors molded together in a single cycle. This process can support complex designs while reducing the need for separate molding operations or later assembly. Midwest Molding supports two-shot programs with tool build management, project engineering, cradle-to-grave management, and production ramp-up coordination.

Insert molding combines plastic with pre-existing inserts during the molding process. Overmolding injects plastic over pre-existing parts, substrates, or inserts to create multi-component assemblies. These processes can support components requiring integrated materials, encapsulation, or an assembled form. Midwest Molding provides engineering, tooling, equipment, and quality support for these applications.

Yes. Midwest Molding supports mold flow analysis, part re-formulation for cost-saving opportunities, error proofing, re-design optimization, and the design and implementation of dedicated manufacturing cells. Project and manufacturing engineers work with customers on complex molded components, tooling coordination, process requirements, and production support.

Customers can contact Midwest Molding through its website or by phone at 224.208.1110.
