Partial plating is an intermediate process for Toshin’s manufacturing customers. The process can often be difficult due to fluctuations in the processing quantity and product type. In addition, the variety and quantity of items have increased, and it has become more difficult to store them in a fixed location due to a shortage of storage space. Since multiple pieces of the same material are delivered with a first-in-first-out method, matching both the type and lot is necessary. Employees end up spending a lot of time searching for materials and stored items, which is a waste of time.
