The products widely applies in defense, medicine, steel, cement, petrochemical, electric power, shipbuilding, electronic, machinery, construction and so on. With the globalization of the competitive market, the casting already has been in the open international environment, with the newly-emerging nations developed fast, like the China and Southeast Asia where by the extremely low labor cost superiority caused the greatest impact on the domestic casting industry. The current important topic is how to promote the quality in order to reduce the cost in face the globalization of the competitive market. The casting divide into both normal and special that the centrifugal casting is one of special methods and can be saving-material, cost-effective. The research applies 8D methodology to improve the centrifugal casting process quality. First of all, we identified the critical quality characteristics and evaluate the measurement system, as well as find out the key factors which affect the process and will be optimized by the design of experiment. The result shows the defect rate was reduced 0.4%, effectively improve the process quality, and save production costs. Keywords : Golf head,Centrifugal casting process,8D.
