Quality Management and Control of Mold Manufacturing Products Based on SPC

Abstract

According to the characteristics of quality management and control in mold manufacturing process, this paper adopts SPC technology to solve the problem of mold production quality control. First of all, it expounded the mechanism of SPC to control the quality and take the machining process of the stamping die mold as an example, using statistical techniques to control the production process quality effectively; Secondly, by using control chart, whether the production process in a state of statistical control could be quickly determined, and the fixture loosening caused by abnormal production would be found and eliminated timely; Finally, through the process capability analysis, the level of process ability could be timely understood, and then two effective measures of improving production processes were put forward in order to reduce the feed rate and improve the process ability of workers.
