Study And Pratice On Six Sigma For Socket Manufacture Process Improvement

Our country has been the member of WTO for years. The corporations have been faced with the stinging competition coming from the Multi-National Corporations. At the present time, the average capability of the corporation in Europe and USA has approached 5 sigma, and it has over 5.5 sigma in Japan. But the average capability in our country has lower than 3 sigma. Now, the management of six-sigma has been thinking as the effective way to acquire benefits depend on quality in most corporations. It has developed and become the best practice way in improvement of strategy, transformation of operation and solving problems. If the Chinese corporations want become greater, they should learn the management of six sigma and bring it into effect at once.It is as follows which the central content and major innovation of this dissertation.1. It dissertated the theory of six sigma systematically, including the meanings, system frame, key technique and tools. Then it expatiated the difference and contact between six sigma and other quality management theories. Those could lead the corporations to catch the pitch of management of six sigma.2. The theory has been applied in Fu Ding precision component Co. Ltd. It based on the fact of Fu Ding precision component Co. Ltd (for short :Fu Ding), such as organization, function of department and so on. At the same time, it has established the organization of six sigma in Fu Ding, confirmed the procedure and implemented process of project , developed the key techniques and tools of six sigma based on the management system and work experience of Fu Ding. All those could guide and promote the corporation bring the management of six sigma into effect.3. It has carried the six sigma project into execution under the leading of the theory studied, procedure and implement process of project confirmed and the key techniques and tools developed. The dissertation delivered one project: about how to improve the yield rate of socket. The effect obtained by this project proved the correctness of programming and organizing about six sigma in Fu Ding. They not only assured Fu Ding can expansion the six sigma in right way, but also provided the reference to other similar corporations in carry on the management of six sigma.4. With the theory studied and the actual projects carried, the author summed up the misconstrue, factors affecting the corporation to implement six sigma. Then list the strategies to carry the management of six sigma. At last, it brings forward the opinion about how to look on the six sigma sensibly and the work of next stage.
