Through intensive analyzing the control cartography's principle and effect of theStat. Process Control's SPC Theory, this paper expounds the Stat. Process Control'sSPC Theory's application in manufacturer production procedure, and confirms SPCtheories' scientificity and accuracy to control the lorry bodywork's paint thickness.
Make sure to adjustproduction requirement as the state of working procedure accordingly, implement theguideline of “finding out discrepancy, taking measures, pledging elimination, being inaccordance with criteria, eradicating its recurring”, maintain the stable state ofworking procedure, and improve procedure capability on product quality so as tomake the paint thickness of lorry bodies' end-walls and side-walls' outsides steadyand ameliorative, and to boost up competition of product in market.
Aiming at lorry paint thickness of JJ plant, this paper is strictly deduced by Stat.Process Control Theory, finds out the reason which causes the troubles of the lorrybody paint thickness on control cartography and performance index, and takesmeasures to reconstruct production line, and finally improves performance index ofproduction procedure, enhances control level of paint thickness rapidly.
Based on the case of study of the end walls' and the side walls' outsides paintthickness quality control of JJ plant, the paper puts forward some views andsuggestions to quality control lag after many state enterprises' technical revamping.
Xing-ping Paints, a small firm not so famous in the industry, through the re formation of their operating system, changes a lot in recent years. Last year, their economic results come out in front of the industry. HOw they were doing in this event. the author tells the story.
