Cost of Quality Optimization in Sand Casting Operations

Abstract

Sand casting is one of the oldest methods applied in foundries industry. However, this method has several disadvantages such as high consumptions of energy. It has an impact on total cost production per pieces. In other side, the problem of cost of quality need an appropriate approach to reduce this cost immediately. This study proposed the alternative sand casting process, CRIMSON (Constrained Rapid Induction Melting Single Shot Up-Casting), to investigate the differences between this methods. The result of this study was indicate clearly that CRIMSON sand casting has a lower total cost per pieces which is the result of lower energy consumption and no cost in sortation and rework because the process was in statistical control.
