Ningbo OEM is also a full-service plastic injection parts manufacturer providing prototyping, manufacturing and assembly. We provide small- to medium-sized custom plastic injection molded components and assemblies for a wide range of applications. In addition to manufacturing, we offer complete value-added services, including design assistance, 3D injection molded prototyping, decorating, assembly and clean room packaging.

Our plastic injection molding process produces custom prototypes and end-use production parts in 15 days or less. We use aluminum molds that offer cost-efficient tooling and accelerated manufacturing cycles, and stock of a wide variety of injection molding grade resins and exotic materials as below: ABS Plastic, Acetal (POM), Polycarbonate (PC), Polyethylene (PE), Polyethylene Terephthalate (PET), Polypropylene (PP), Polyvinyl Chloride (PVC), Acrylic (PMMA),etc.

How Does Plastic Injection Molding Work?

The thermoplastic injection molding process at Ningbo OEM 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. It allows our molders to monitor fill 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.
