Increasing the Overall Equipment Effectiveness in Auto Part Press Machine

This research aims to increase the overall efficiency of the machinery in the automotive parts stamping production line. Mahle Siam Filter Systems Co., Ltd. has a plan to improve the machinery in the production of automotive parts. Before the improvement, it was found that the overall performance improvement was lower than the desired target. The improvement focus on increasing the availability rate by using Pareto chart tools and Why-Why Analysis to analyze causes and remedy the problems, SMED (Single Minute Exchange of Die) technique to reduce the setup time of the press machine, and ECRS (Eliminate Combine Rearrange Simplify) technique to eliminate wasted waiting time. After improvement in the machine set up, it was found that the machine setup time decreased on average from 51.89 minutes to 18.14. minutes. As a result, the average availability rate increased from 62.1% to 72.3%, and overall equipment effectiveness increased from 58.7% to 69.2%.
