ABSTRACT
quality caused by molding structure, as well as the casting system design, partial and general design of mold moulding introduced respectively. The critical points of mold Abstract :The molding process of plastic parts, the effect analysis to plastic parts for plastic design are introduced, and the adjustable character of molding structure、exchange character as well as the molding costs are all considered farther. Starting from controlling dimensional accuracy, the carry the cover to the main dimensions of injection molding are carried out so as to determine the size of different parts, the molding design and the process of parts as well as assembling process and etc of injection molding are stated in details.
Key words: process analysis; plastic parts moulding; casting system; molding structure.
