The case company performed about 6 setups per day, with an average setup time of 58.67 minutes per setup, resulting in a total setup time of approximately 352.02 minutes per day. The Single Minute Exchange of Dies (SMED) technique, based on the principles of Shigeo Shingo, was applied. The machine setup was divided into 7 stages to suit the needs of the case study company. After the improvements, the setup time was reduced to 31.97 minutes per setup, resulting in a 45.51% increase in machine operation efficiency. The tools and techniques used in this research can be applied to similar machines for continuous improvement.Materials ScienceEngineeringConference PaperSCOPUS10.4028/p-MWwj482-s2.0-10500751487616629795
