Multi-variable interaction analysis and a proposed quality control system for thermoplastics injection molding

Injection molding is a multi-variable process in which many variables interact to influence the molded part quality. fn this paper, the major machine, process, and material variables are considered and analyzed for their interrelation, and several process variables are chosen to farm the key variables for an over-ail quality control system far tile injection molding process. The overall quality control system is proposed to be of a distributed, 3-layer structure, and its implementation is briefly discussed
