Large Part Injection Molding Services

The practical size of an injection mold depends on the part design, mold construction, machine requirements, and production process. Midwest Molding operates injection molding machines ranging from 55T to 950T capacity, giving its engineering team a basis for evaluating large and complex components. A project review can determine suitable tooling, equipment, and process requirements for a specific part.

An injection mold commonly includes mold halves, cavities, cores, runners, gates, cooling passages, ejector components, and a mold base. The exact configuration varies with the component, resin, tooling strategy, and production requirements. Midwest Molding supports tooling design and build with mold flow analysis and project engineering for prototype and production tools.

Midwest Molding supports automotive, transportation, electronics, consumer goods, appliance, HVAC, and related manufacturing applications identified in its customer segments and service descriptions. Its capabilities include straight injection molding, insert molding, two-shot molding, overmolding, tooling, and assembly for complex plastic components and integrated products.

Large part injection molding is used to produce substantial or complex plastic components and assemblies with repeatable processing. Applications may include automotive and transportation components, electronic housings, appliance and HVAC products, consumer goods, and molded assemblies. The appropriate process depends on part design, materials, inserts, tooling, and production requirements.

Yes. Midwest Molding provides cradle-to-grave project management for prototype and production tool design and build. Support includes mold flow analysis, dedicated project engineering, part reformulation for cost-saving opportunities, and coordination through production ramp-up. The team can evaluate tooling requirements alongside the intended molding process and component design.

Yes. Pre-mold and overmolding places plastic over pre-existing parts, substrates, or inserts to create multi-component assemblies. Insert and composite molding combines materials through injection molding for complex components. These services are supported by electric molding equipment, dedicated tooling and process resources, project engineering, and quality control systems.

Yes. Midwest Molding provides multi-component assembly that combines injection molded parts with additional components into complete assemblies. Its support includes cradle-to-grave project management, error proofing, redesign optimization, and dedicated end-of-arm tooling. Wire harness assembly is also listed among its specialized manufacturing capabilities for relevant programs.
