ABSTRACT:
The present invention provides a method and system for controlling the quality of a product produced by an injection molding production process. The invention includes performing a multivariate analysis on injection molding process data collected real-time and determining whether the real-time data is within a predetermined production control limit. When the real-time production data exceeds the control limit, the process is considered out of control and product produced during the out of control condition is removed real-time from the injection molding production process.
