Our Injection Molding Process
Our injection molding process is structured, transparent, and easy to follow.
We start with a detailed design and engineering review to confirm material selection, part geometry, tolerances, and end-use requirements. Early feedback helps prevent delays and unnecessary revisions.
Next, high-precision injection molds are designed and manufactured. Tooling quality is essential for consistent part accuracy and long mold life.
During production, plastic resin is melted and injected into the mold under controlled pressure and temperature. This ensures uniform filling and structural integrity.
Parts are cooled, ejected, and inspected for dimensional accuracy and surface quality. Quality checks are built into every stage of production.
Once approved, production scales efficiently with repeatable cycles, supporting rapid injection molding in Lake Saint Louis and long-term manufacturing programs.
