Injection molding
High volume manufacturing
SunHui specializes in low-to-high-volume plastic injection molding for a wide range of industries including industrial, medical, marine, aerospace, & consumer products. With a diverse array of resins, equipment ranging from 80 to 3500 tons, including over molding,2k molding and high speed injection capacities.
How does plastic injection molding work?
The thermoplastic injection molding process at SunHui 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 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
Some common materials for injection molding include, but are not limited to:
Acrylonitrile butadiene styrene (ABS)
Polycarbonate copolymer acrylonitrile butadiene styrene (PC ABS)
Liquid-crystal polymer (LCP)
Acrylic (PMMA)
Nylon (PA6/66)
Polypropylene (PP)
Polystyrene (PS)
Polyethylene (PE)
How do you create aesthetic plastic parts with plastic injection molding?
Creating aesthetically pleasing plastic parts through injection molding involves careful design, material selection, mold design, molding process control, and post-processing techniques. By optimizing these factors, manufacturers can achieve high-quality parts with desired surface finishes and visual appeal.
