Low Volume Custom Injection Molding for OEM Production

Low volume custom injection molding produces customer-specific plastic components in quantities suited to an OEM’s production requirements rather than standardized catalog parts. The work may include tooling, straight injection molding, insert molding, overmolding, two-shot molding, and assembly. Midwest Molding, Inc. supports these programs with project engineering, mold flow analysis, process optimization, and quality assurance capabilities.

Midwest Molding supports complex molded components and assemblies for automotive, transportation, electronics, appliance, consumer goods, and related manufacturing applications explicitly served by the company. Capabilities include plastic components with inserts, multi-material or multi-color parts, overmolded assemblies, wire harnesses, and other integrated products developed with customer-specific tooling and engineering support.

Yes. Midwest Molding provides cradle-to-grave project management for prototype and production tool design and build. Support includes mold flow analysis, ES testing, part re-formulation for cost-saving opportunities, and dedicated project engineering for complex molded components. The tooling service is intended to support programs from development through production requirements.

Insert molding combines plastic with an inserted component during the molding process, while overmolding injects plastic over a pre-existing part, substrate, or insert. Both approaches can create multi-component assemblies and integrate materials into a finished component. Midwest Molding supports insert, composite, pre-mold, and overmolding applications with engineering, tooling, equipment, and quality control support.

Yes. Midwest Molding offers two shot molding, which enables multiple materials or colors to be molded together in a single cycle. The service is supported by manufacturing and project engineers who manage the program from tooling design through production ramp-up. Insert, composite, and overmolding capabilities also support complex multi-component product requirements.

The company supports design optimization through mold flow analysis, part re-formulation, error proofing, and re-design optimization. These services can help identify cost-saving opportunities, improve manufacturability, and maintain part functionality and quality. Dedicated project engineers collaborate across tooling, process development, molding, and assembly requirements for complex OEM components.

Company information lists IATF 16949, ISO 14001:2015, ISO 14001:2004, ISO 9001:2008, ISO/TS 16949:2009, and Minority Business Enterprise certification. The company also records certification history for its quality management and environmental management systems. Customers should confirm which certification applies to their specific program and current production requirements.

An OEM can begin by sharing its component design, application requirements, anticipated production needs, and tooling objectives with Midwest Molding. The company can then evaluate relevant molding, tooling, assembly, and engineering capabilities, including straight injection molding, insert molding, overmolding, two-shot molding, or multi-component assembly.
