How Does Plastic Injection Molding Work?

The manufacturing process for molded parts is complex. Before your parts are even molded, we’re there to help you with comprehensive manufacturability feedback and consultative design services, so you can avoid mold design pitfalls before the resin hits the mold. From there, our production process is documented and optimized using scientific molding so you get high-quality parts consistently and reliably with every production run.

Critical-to-quality (CTQ) dimensions you call out on models let us know what areas are most crucial to the success of your parts. Once the parts start molding, the process and samples are qualified using automated inline CMM technology, generating a detailed FAI and process capability study with no additional lead time.

Our thermoplastic injection molding is a standard process involving an aluminum mold with no heating or cooling lines running through it, which means cycle times are a bit longer. As part of the scientific molding process, our molders independently optimize and monitor fill speed, hold pressure, and hold time, and periodically inspect part quality and cosmetics. During the molding process, we use an automated inline CMM to ensure dimensional accuracy, as well as generate a detailed process capability study and FAI report.

Resin pellets are loaded into a barrel where they will eventually be melted, compressed, and injected into the mold’s runner system. Hot resin is shot into the mold cavity through the gates and the part is molded. Ejector pins facilitate removal of the part from the mold where it falls into a loading bin. When the run is complete, parts (or the initial sample run) are boxed and shipped shortly thereafter.
