Toshin Industry Co., Ltd., a leading hoop plating company, was facing a significant challenge in managing the variety and quantity of items in their four factories. The company, which plates the contact points of electronic components for devices like smartphones, tablets, and personal computers, was struggling with storage space due to the increasing number of items. This issue was further complicated by the fact that multiple pieces of the same material were delivered, necessitating a first in, first out approach and matching of type and lot. As a result, employees were spending an excessive amount of time searching for materials and stored items, leading to a waste of valuable time and resources.
