In recent years, against the backdrop of diversifying customer needs, “high-mix low-volume production” has become mainstream in manufacturing sites. However, this method of handling a wide variety of products in small quantities while switching production lines presents unique challenges in terms of parts procurement.
In response to these challenges, Ohta Vietnam offers a supply chain solution optimized for high-mix low-volume production as a “specialist in local procurement of fastening parts.”
Ohta Vietnam’s service streamlines ordering operations at manufacturing sites, reduces inventory risk, and realizes stable procurement of high-quality screws. In the next chapter, we will explain its strengths in more detail.
Centered on our manufacturing and logistics bases in Ho Chi Minh City and Dong Nai Province, we centrally manage everything from procurement to shipping within Vietnam. By not going through Japan, we reduce conventional time loss. Our “vertically integrated system,” in which the production control department directly coordinates, enables delivery within a minimum of 3 business days after parts procurement.
We have introduced an inventory management system that uses handy terminals and QR codes. Inbound and outbound data is immediately reflected in the cloud system, eliminating data discrepancies between the site and the management screen. This makes it possible to order “just the right amount at the right time” even for frequent inbound and outbound shipments of a wide variety of products, and simultaneously reduces the risk of stockouts and excess inventory.
We have established an in-house quality assurance department and have obtained ISO9001:2015 and ISO14001:2015 certification. We are fully equipped with advanced inspection equipment such as 3D measuring machines and image measuring machines, and have established multiple checkpoints at each stage of the manufacturing process. We also require our partner companies to maintain the same level of quality control, and maintain high quality based on Japanese-style know-how.
Based on inventory data collected by IoT and past order history, we automatically simulate the optimal order lot using ABC analysis and EOQ (Economic Order Quantity) theory. Automatic ordering settings linked to a weighing scale are also possible, which suppresses logistics costs and also reduces administrative man-hours by consolidating the number of orders. As a result, we have a track record of reducing procurement costs in high-mix low-volume production by up to 20-30%.
This is a case study of a small and medium-sized machinery manufacturer that was struggling with a monthly storage cost of about 500,000 yen by managing dozens of types of screws as in-house inventory. By utilizing Ohta Vietnam’s “Vietnam local inventory + regular air freight,” the following improvements were seen.
This is a case study of a medical device parts manufacturer A, where about 15 ordering errors (wrong part number, insufficient quantity) per month were a risk of production line stoppage. By introducing our “IoT x barcode inventory management system,” the error rate was dramatically improved.
With this mechanism, ordering errors, which used to be 15 per month, have been drastically reduced to less than 1 per month. The risk of delivery delays due to line stoppages has been almost eliminated, and we have succeeded in reducing opportunity loss equivalent to about 2 million yen annually.
To choose a procurement partner that can handle high-mix low-volume production, please check the following four points.
Ohta Vietnam’s screw procurement service simultaneously solves the “cost,” “delivery time,” and “quality” challenges of high-mix low-volume production by combining a local network in Vietnam, IoT inventory management, a highly reliable quality assurance system, and a cost optimization mechanism.
As the case studies show, we have achieved concrete results such as a 30% reduction in inventory costs and a reduction of over 90% in ordering errors. You can experience the effects even from a small-scale test order. Please consider our service to build a flexible and robust supply chain and enhance your competitiveness.
