Our Injection Molding Process
Our injection molding process is designed to be clear, efficient, and dependable.
We start with a detailed design and engineering review to confirm part geometry, tolerances, material selection, and manufacturability. Early analysis helps prevent redesigns and production delays.
Next, high-precision injection molds are engineered and manufactured. Tooling quality directly affects part accuracy, surface finish, and mold longevity.
Selected plastic resin is melted and injected into the mold under controlled pressure and temperature to ensure uniform filling and structural integrity.
After cooling, parts are ejected and inspected for dimensional accuracy and visual quality. Quality checks are integrated throughout production.
Once approved, production scales smoothly, supporting rapid injection molding in Mercer Island and consistent long-term output.
