碩士 === 國立高雄大學 === 亞太工商管理學系碩士班 === 100 === The characteristics of the precision casting products include high dimensional accuracy, low cost materials and machining, complicated shapes, various thickness, hollow casting available, and excellent mechanical properties. Demonstrating the characteristics of a product, however, requires techniques such as mature product development, manufacture process designs, quality management systems, and production management. Casting quality and dimension are associated with some important casting processes, including injecting wax, assembling patterns, ceramic molding, and casting. In order to avoid the operational variation, engineers usually make the standard operation procedure as well the procedure control chart. In consequence, this study intends to discuss the issue about how the mechanical property and the qualified rate are related to the factors like injecting wax control, test value analysis of ceramic slurry, influence of alloy incoming ingredient, alloy purity, and suppliers. It is hoped that the research results will help provide a better choice for company A in the future process control.
