Analysis of Overall Effectiveness on Hall Separator Punching Machine at PT. DNIA

Abstract

PT. DNIA is a company engaged in manufacture of automotive parts, one of which is condenser. Manufacture of condenser components requires small parts produced using a hole separator punching machine. However, it deals with high downtime of the machine, resulting in low production performance. This research aimed to identify the extent of hole separator punching machine performance using analysis of Overall Equipment Effectiveness (OEE) and to analyse six big loses which impact on machine downtime. Calculation results show that OEE value obtained, 48.54%, was still below the standard, and therefore continuous improvement attempt is essential to perform. The low OEE value was a result of low performance efficiency which was caused by idling and minor stoppages of 24.54%. In order to improve the performance and carry out idling and minor stoppages loss, it is important to perform improvement attempt in a number of aspects, such as man aspect by training operators to carry machine-related works, machine aspect by repairing abnormal ups and downs of dies, and material aspect by fixing inappropriate position of header tank (material).
