Expertise You Can Count On

  • Materials Knowledge → From commodity resins to advanced engineering blends, foamed or solid, we match materials to your application.
  • Tooling Excellence → With over 200 years of combined tooling experience and a fully equipped tool shop, our engineers ensure molds are built right the first time.
  • Simulation-Driven Design → Using Autodesk® Simulation Moldflow®, we model flow, cooling, and filling to predict and solve problems before steel is cut.
  • Design for Manufacturability (DFM) → Every mold and part design undergoes review to balance performance, durability, and cost-effectiveness.

A Proven Process for Success

  • Early design review meetings with engineers and toolmakers
  • CAD design with SolidWorks
  • Rapid prototyping and timeline planning
  • Contingency planning for risk reduction
  • Domestic and offshore tooling sources for flexibility

The result: molds that perform, parts that meet spec, and programs that launch smoothly.
