Custom Injection Molding

Custom Injection Molding

Precision injection molding built around your part, application, and production requirements. From specialized components to ongoing production programs, we deliver consistent quality across automotive, industrial, agricultural, consumer applications, and many more.

  • Material: engineering resins selected to meet your part’s performance and application requirements.
  • Capabilities: custom injection molding, insert molding, and overmolding—all supported in-house.
  • Production: flexible production capabilities for both lower-volume and high-volume programs, with a focus on consistent, repeatable quality.
Engineering Support

Engineering Support

From initial concept to production-ready design, we work directly with your team to develop practical, manufacturable solutions that meet your performance, quality, and production requirements.

  • Collaboration: direct communication between your team and ours throughout the development process.
  • Design Support: review and refinement of part designs with manufacturability, material selection, and performance in mind.
  • Optimization: identify opportunities to improve part quality, simplify production, and reduce cost before production begins.
Part Design

Part Design

We turn concepts, drawings, and existing designs into production-ready plastic components. Our team focuses on creating parts that perform as intended while being optimized for reliable and cost-effective injection molding.

  • Manufacturability: part geometry, wall thickness, draft, and other critical features are evaluated early in the design process.
  • Performance: materials and design features are selected around the part’s function, operating environment, and performance requirements.
  • Efficiency: designs are optimized to simplify manufacturing, improve consistency, and reduce unnecessary tooling and production costs.
Rapid Prototyping

Rapid Prototyping

Evaluate and refine your design before moving into production. Rapid prototyping allows you to verify form, fit, function, and performance while identifying potential design changes early in the development process.

  • Validation: evaluate critical dimensions, fit, function, and overall design before committing to production tooling.
  • Refinement: identify and address potential design issues early, when changes are easier and more cost-effective to make.
  • Confidence: move into tooling and production with a proven design and a clearer path to a successful finished part.
Tooling

Tooling

From prototype tooling to full production molds, we develop tooling around your part, material, production requirements, and long-term manufacturing needs. Our focus is reliable performance, repeatability, and efficient production.

  • Design: tooling engineered around part geometry, material, production volume, and molding requirements.
  • Capability: solutions ranging from straightforward mold designs to more advanced runner, gating, and tooling configurations.
  • Performance: designed with cycle efficiency, part quality, reliability, and maintainability in mind.
Value-Added Assemblies

Value-Added Assemblies

Our capabilities extend beyond molding. We provide secondary assembly and finishing services to help deliver more complete, production-ready components while reducing the number of suppliers and processes you need to manage.

  • Assembly: component assembly, hardware installation, fastening, and other secondary operations based on your requirements.
  • Quality: assembly processes and finished components are checked to help ensure consistent quality before shipment.
  • Packaging: parts can be counted, labeled, packaged, and prepared to meet your production and delivery requirements.
