Using Profile Approach to Managing Thermoforming Process of Automotive Decoration Parts

In many manufacturing/ service cases, a process is monitored effectively by a functional relationship between an independent variable(s) and a response variable rather than measurements on a single quality specification or a quality specification vector. This regression relationship is referred to a profile in the statistical process control literature. Scientific reports address profile monitoring leads to a more effective quality management in the case that the relationship function is adopted correctly. Profile approach helps an industrial process management to analyze the behavior of quality specifications by a curve. In this paper, the management of thermoforming process for a cover part of the fender of SAMAND automotive is investigated. The model proposed for phase-I of this research address the capability of monitoring the process for phase-II of statistical control.
