Abstract

Defective product is an undesirable quality product deviation in production process. Defective product is one of main problems in industry. A casting process of motor cycle cylinder component has defective product problems at 4.47% rate. This research aims to reduce the problems with determined target at 3.6%. Plan Do Check Action (PDCA) methods with seven tools as quality assistance instrument is used to analyze the problem and to develop corrective action. The analysis indicated that causes of the problem are undercut and porous on cylinder component. The corrective action related with material, machine and inspection were taken. The result of the corrective action shows a defective product rate at 3.17%. The preventive action was performed to diminish the potential causes of incompatible product for preventing recurrence in the future.
