Our system is based on the Toyota production system which stimulates the short lead time and cost reduction. Yamagata facility enhances the self-manufacture system including the cutting, salt bath, welding, grinding, surface treatment, and assemble. Therefore, we can produce in the short lead time by one piece at a time production system.
