ABSTRACT
PT. GTC is a company that produces automobile tubes facing problems with an increase in demand of up to 20% from the previous year. From 4 existing divisions named mixing, extruding, splicing, and curing, it was found that the extruding division was unable to meet the production targets set by the company. There are several causes, including high setup time. This research aims to reduce setup time by applying the Single Minute Exchange of Die (SMED) method to the production process in the extruding machine-1 that produces automobile tube sizes 5.50-13 and 7.00-14. Converting activities no. 2, 3, and 14 from internal activities to external activities, changing the layout of the die, core, and adjuster key storage table, dies unification, and installing a Temperature Control Unit to control steam to the extruder head can reduce setup time from 45 minutes to 22 minutes or 51% from the initial setup time. These improvements succeeded in increasing the productivity of the extruding division up to 93.9% in January 2023.
