In High Pressure Injection Molding, plastic material is feed into a heated injecting unit. A reciprocating screw forces the plastic through this long heated chamber where the material is softened to a fluid state. At the end of the chamber is a nozzle which sits firmly against a opening into a cool closed mold. The fluid plastic is forced under high pressure through the nozzle into the cooled tool. After cooling the tool opens and the the part is ejected and the cycle repeats.
Parts molded via high pressure injection molding process typically exhibits consistent wall thickness superior cosmetic, great complexity and tight dimensional control.
