Utilizing the technology cultivated in the manufacturing of products with complex curved surfaces, such as the front structure of Shinkansen vehicles, we also accommodate the production of interior and exterior components. 【Overview】 Processing Method: Bending processing using a craft former Size: 1t×50×50 Length 500 Radius 300 (mm) *Please consult with us Material: Stainless steel, aluminum, iron, etc. Lot Quantity: 1 to 100 *Please consult with us <Customer Feedback> I was looking for a company that could process R-shaped designs because I wanted to stylishly outline the curved windows in the design. *For more details, please download the PDF or feel free to contact us.

• Processing Contract

We offer sheet metal processing for construction and interior design, utilizing the technology developed from creating the faces of Shinkansen train cars, including baseboards and corner covers. Our stamping sheet metal is suitable for small production runs without the need for molds and can accommodate curved and complex shapes. 【Overview】 Processing Method: Stamping Sheet Metal, Welding Size: 1.5t × 30 × 30 × 50 *Please consult with us Materials: Stainless Steel, Aluminum, Iron, etc. Lot Size: 1 to 100 *Please consult with us <Customer Feedback> I want to round the corners, but the quantity needed is small, and machining is not cost-effective. With stamping sheet metal, I can produce small quantities with flexible shapes, so I would like to consider it. *For more details, please download the PDF or feel free to contact us.

• Processing Contract

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.

• Processing Contract

Our company performs metal curved surface forming using the "Craft Former (sheet metal sequential forming machine)," which allows for curved processing without the use of fuel through cold processing. Since welding work and dedicated molds are not required, it is possible to reduce labor and costs. We can also accommodate prototypes and small lot production, achieving short delivery times. Additionally, because no fuel is used, carbon dioxide emissions are minimized, contributing to the reduction of environmental impact. 【Features】 ■ No cutting process, which helps minimize material loss ■ Capable of reproducing architectural materials and objects with smooth curves in metal ■ Over 50 years of experience in manufacturing leading structures and internal components for the Shinkansen, which serve as its "face" *For more details, please refer to the materials. Feel free to contact us as well.

• Other contract services

It is possible to reproduce corners of buildings, awnings, and covers of design shapes by bending a single sheet without any seams from welding. The advantage is that there are no seams, which prevents water and air from leaking. Additionally, there is no distortion from welding, allowing for a smooth and beautiful appearance. If you have any thoughts on how this technology could be utilized or ideas for potential applications, I would be grateful if you could reach out.
