How does plastic injection molding work?

The thermoplastic injection molding process at Folin is a standard process involving an mold with heating or cooling lines running through it to make the shorter cycle time and improve the surface quality. It allows our molders to monitor filling pressure, cosmetic concerns, and the basic quality of the parts. 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. 

Ready for a more cost-saving and time-efficient way to manufacture plastic parts? Our high mold manufacturing knowledge and strong engineering team help you reduce design risks and limit overall production costs along every step of the product cycle. At Folin, our injection molding and die-casting services are designed for both low-volume and mass production of end-use parts, production tooling for high-volume production, mass customization of product lines. Our plastic injection molding processes produce custom prototypes and end-use production parts in 15 days or less.
