Abstract

Improving the efficiency of mold storage management case study of the plastics manufacturing industry.The objective is to study the mold storage management process, reduce the time and distance to search for molds for production and reduce storage space. By collecting information Analyze causes and factors affecting mold storage management using cause-and-effect diagram. Then the ABC analysis was applied to grouping and categorizing according to frequency of movement or handling and proceed with rearrangement according to the principle of reducing waste with ECRS by creating a map showing work areas, install signs indicating storage areas by category. The results of the improvement found that the storage efficiency increased. From the original, the mold was placed in the wrong place 100%, after the renovation, there was no misplacement. Search time was reduced with employees at the mold warehouse using the original search time of 8.8 minutes/ set. After improvements, the time decreased by 2.5 minutes/set, accounting for 28.4%. The replacement employee, the search time from the original took 11.4 minutes/set, after improvement, time decreased by 4.6 minutes/set, accounting for 40.35%. The designated mold storage area is 175 m 2 , from the original 193 m 2 , reduced to 160 m 2 , with remaining space of 15 m 2
