Vertical Insert Molding Services for Complex Parts

Vertical insert molding places a pre-existing component, such as a metal insert or other substrate, into a mold before plastic is injected around it. The process creates an integrated component that can reduce separate assembly requirements and support complex designs. Midwest Molding provides insert and composite molding with tooling, engineering, equipment, and quality support for production programs.

Insert molding may use metal components, electrical contacts, substrates, or other pre-existing parts when the design and process requirements are appropriate. The insert must be compatible with the mold, material, and production method. Midwest Molding’s project engineering team can provide guidance on molding processes, tool build, and process requirements for complex molded parts.

Yes. Midwest Molding manages prototype and production tool builds with cradle-to-grave project management. Tooling support includes mold flow analysis, ES testing, and part re-formulation for potential cost-saving opportunities. The team also provides dedicated project engineering support for complex molded components and production programs.

Midwest Molding supports automotive, electronics, consumer goods, transportation, and appliance manufacturing applications. Common requirements include insert-molded and overmolded components, automotive and electronics components, wire harness assemblies, and other complex plastic parts.

Yes. Midwest Molding offers insert and composite molding, pre-mold and overmolding, and two-shot molding as related capabilities. Overmolding can encapsulate pre-existing parts or substrates, while two-shot molding combines multiple materials or colors in a single cycle. Project engineers help determine the appropriate process for the component design and production requirements.

Midwest Molding operates a 120,000-square-foot facility with 55 fully electric injection molding machines. Its press fleet includes 50 horizontal and 5 vertical all-electric machines, covering a broad range of press sizes for straight, insert, and composite molding. The facility also includes dryers, mixers, grinders, robots, sprue pickers, and end-of-arm tooling.

Yes. The company supports prototype and production tool build management, project engineering, mold flow analysis, part re-formulation, and production ramp-up. Its cradle-to-grave project management approach is intended to coordinate tooling and manufacturing requirements across the life of a program, from early development through ongoing production.
