【Abstract】 The quality of coatings on the inner surface of aluminum-based high-voltage switch housing has become the constrains for the operation of high-voltage switch production.In view of the problem of coatings particles on the inner surface of high voltage switch,this paper discussed the quality improvement model of DMAIC. On the basis of qualitative analysis of potential factors affecting the coatings quality for high voltage switch housing by using SIPOC and FMEA models,the root causes and the optimal combination of parameters was analyzed by experimental design. The feasibility of the improved scheme was verified by practical production cases.更多还原
