Even small and complex shapes can be beautifully realized with stamped sheet metal. Using the techniques developed in creating Shinkansen designs, we will bring your products to life.

Our company has been manufacturing the front structure (the "face") of Shinkansen trains since the year before the Tōkaidō Shinkansen opened. For half a century, we have been engaged in sheet metal processing of Shinkansen vehicle parts as a certified cooperative factory of Hitachi Works Kasado, which is a production base for vehicles in the Hitachi Group. 【Overview】 Processing methods: Craft former, stamping Sizes: Please consult us Materials: Stainless steel, aluminum, iron, etc. Lot sizes: 1 to 100 *Please consult us <Features> ■ For small quantities, we can reduce manufacturing costs compared to machining and mold forming, as there are no dedicated molds. ■ No welding, thus no welding distortion or heat effects. ■ Energy-saving and material-saving compared to machining.  → No cutting oil required, minimal chips for environmental consideration. ■ Surface finishing options available (plating, anodizing, mirror finish, painting). *For more details, please download the PDF or feel free to contact us.

This is a sheet metal processing company that was established the year before the Tōkaidō Shinkansen began operations to manufacture the streamlined front body (the part referred to as the "face"). As a certified partner factory of Hitachi, Ltd., we produce not only the front body but also sheet metal parts for the driver's cabin and control panel. We have a manufacturing track record of over 400 vehicles across 25 models, from the 0 series to the latest E8 series of Shinkansen. Our craftsmanship, which allows us to create various single items and small production parts composed of three-dimensional curved surfaces without the use of press molds, has been recognized (Japan Monozukuri Award, Regional Future Leading Company). We are expanding the applications of our Shinkansen parts manufacturing technology, particularly into new fields and products such as architectural sheet metal with three-dimensional curved surfaces and industrial machinery and equipment. We accommodate the transition from hand-drawn sketches to two-dimensional and three-dimensional CAD data, as well as miniature modeling with 3D printers and prototypes. We have obtained the SBT certification for small and medium-sized enterprises and the Yamaguchi Renewable Energy Power Utilization Business Certification (100% renewable energy rate). We are an investment recipient of the Osaka Small and Medium Enterprise Investment Development Company (government-affiliated VC). Utilizing techniques for three-dimensional curved surface shaping with stamping sheet metal and forming processing machines, as well as aluminum and stainless steel welding, we aim to be a sheet metal processing company that stands in society.
