Our Injection Molding Process
Our injection molding process is designed to be simple, efficient, and reliable for both new and experienced manufacturers.
The process begins with a detailed design and engineering review to confirm manufacturability, material selection, tolerances, and functional requirements.
Next, high-precision molds are engineered and manufactured. Tooling quality directly affects part accuracy, surface finish, and mold lifespan.
Selected plastic materials are melted and injected into the mold under controlled pressure and temperature, ensuring uniform filling and structural integrity.
After cooling, parts are ejected and inspected for dimensional accuracy, appearance, and performance. Quality checks are integrated throughout production.
Once approved, production scales smoothly using repeatable cycles, supporting rapid injection molding in Sudbury and consistent high-volume output.
