We are establishing a production system that flexibly responds to customer needs and evolves towards the future.
At Factory No. 5, we process hydraulic motor parts for Kawasaki Heavy Industries and have introduced a unique U-shaped line for single-piece flow production at Okubo Iron Works. This production system allows us to flexibly respond to fluctuations in customer order quantities. Additionally, we have a general-purpose line that excels in low-volume, high-variety production, enabling us to meet various needs. Furthermore, our factory has space for equipment expansion, allowing us to quickly respond to future increases in production capacity and new demands. We aim to evolve our factory alongside our customers' growth and will continue to pursue further improvements in productivity.
