The Application Research Of Statistical Process Control In Auto Fittings Industry

Statistical process control (SPC) is a method that supplier of mobile maker to set up effective manufacture process control system, in order to produce efficiently and economically. Its basic principle is to adopt statistical method to monitor the peculiarity of output continuously and thereby obtaining the actual performance information of the process in time, accurately in order to response properly to keep the stability of the process. This text draws lessons from the theory and practice of developed country SPC, combines the actual conditions of the fittings manufacturing industry of automobile of our country, first, introduced the basic theory of quality & SPC; then, introduced the application of SPC in the auto fittings industry, provide and use SPC method to set up manufacture process to feedback the basic procedure, mode of execution, result analyses and informatization solution design; Finally, I state practical suggestions according to this research & actual use. The core of this text is that automobile makers follow the relevant demands for SPC application manual in ISO/TS 16949 technical specification, use SPC method effectively, make the quality information of enterprises transmitted rapidly, communicate and analyzed high-efficiently, thus control quality costs, develop potential value thereby enhance the quality control competition.
