No welding distortion and no heat impact because it's weld-free! Bending processing with a craft former requires no cutting oil and generates minimal chips, saving energy and materials.
Using the technology cultivated from the manufacturing of the Shinkansen "face," we produce beautiful curved water drainage systems for architecture and housing. Our products achieve a beautiful finish and high durability without the need for welding. 【Overview】 Processing method: Bending processing using a craft former Size: 1t×50×80 Length 700 Radius 1000 (mm) *Please consult with us Materials: Stainless steel, aluminum, iron, etc. Lot size: 1 to 100 *Please consult with us ＜Case Information＞ Traditionally, water drainage systems for curved wall surfaces were made using welding, which led to issues with rainwater intrusion due to cracking. By adopting a welding-free sheet metal processing method, we have achieved beautiful curved water drainage systems without the worry of water leakage. ＜Customer Feedback＞ "We used to produce water drainage systems for curved wall surfaces using welding, but rainwater would intrude due to cracking. With the welding-free option, there is no concern about water leakage." *For more details, please download the PDF or feel free to contact us.

Company information
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.
