Improving curing process productivity in the tire industry using OEE, TPM and FMEA methods

Abstract

The volume of car sales from time to time continues to increase (Gaikindo, 2020) so the need for supporting spare parts will also accompany it, both as an OEM (Original Equipment Manufacturer) supply in the car industry and to direct users as replacements. Tires are one of the important components, because the movement needs a rotating wheel as the means so that the tire manufacturing industry remains a profitable business. The curing process in the manufacture of tires is an obstacle to increasing the productivity of tire manufacturing, with an average OEE value of 75.86%, still far from the global company level target of 85% and the company's target of 89%. To increase the OEE value, start with the measurement of six big losses followed by a Pareto diagram to find the priority of the problem and the root of the problem using a fishbone diagram. The machine problem is fixed with the TPM program on the machine with the lowest OEE value until Autonomous Maintenance is running, then duplicating it. The FMEA method was used to solve the Rate of Quality problem so that an increase in the OEE value was 89.88% at the end of the study.
