Abstract

The aim of this study is to reduce the number of defects in the metal casting finishing process through the implementation of the Six Sigma method. The study identifies various defects such as pouring metal, mold material, porosity, and shrinkage defects, and provides recommendations to minimize them. The Six Sigma method involves five stages - define, measure, analyze, improve, and control, and the process capability level was found to be 96.47%. However, the sigma and DPMO values obtained were 3,943 and 9,333.36, respectively, indicating that the target of 6 sigma and 3.4 DPMO has not been achieved. The most dominant defect was found to be in the mold material, and this was caused by human factors, machines, methods, and materials. Suggestions for improvement include providing regular training for workers and carrying out intensive maintenance and inspections for each machine used during the production process. The implication of this study is that by implementing the Six Sigma method and adopting the recommendations provided, manufacturers can minimize defects in the metal casting finishing process, leading to better quality products and increased customer satisfaction.
