Lean Six Sigma is an improvement strategy Stimulated by global high-profile enterprises including CE, Motorola, Pfizer and Boeing, increasingly number of enterprises select it and promote its implementation It can be observed, as an important measure, to study Lean Six Sigma and how to effectively apply the management approache of it gives preference to further the development of enterprises Attributing to the high demand in energy-saving lamp, herein energy-saving lamps manufacturing industry is selected Taking its one-off assembly yield as an instance, we integrate the data pre-treatment into the Lean Six Sigma Management Process, employ specific DMAIC implementation pattern and apply measuring system analysis, SIPOC analysis, fishbone diagram, FMEA analysis etc For analysis to reduce in-process defectives, improve first time success ro, thereby to have the operation cost lowered, company quality level lifted and company competitiveness enhanced

Application of lean six sigma in energy saving lamp assembly process

Based on the methodology and tools of six sigma managements, this paper mainly focuses on an automobile steel plate-shearing line, which can be regarded on as a product service system since the supplier of machines provides service after sales. And the result proves that the machining accuracy of product has been improved obviously. It not only shows that six sigma is very effective concept and methodology in manufacturing industry, but also can be learned lesson from and has an important popular significance for more and more product service systems to improve the process control and product quality.

The Application of Six Sigma Management in Product Service System

SPC method is a process controlling tool with the aid of mathematical method. Define, Measure, Analysis, Improvement and Control is the implementation processes of quality management. Combined with the two methods, the quality fluctuation in the production process could be controlled effectively and qualified products rate could be enhanced excellently. In this paper, the film thickness problem of motor shell coating production line has been studied based on statistical process control and DMAIC processes. The Pareto diagram, cause and effect diagram, operation chart are used to inspect production defects in the process. At same time, the factors leading to product defects are determined. Then, DOE method is applied to find the best parameters of electrophoresis coating process. SPC method is adopted to monitor the improved film thickness. The results show that quality level of coating process has improved greatly.

Research on Quality Control of Motor Shell Coating Process
