In-house Equipment [Punching Processing Examples]

Material: Zinc-coated steel plate / Punching pattern: Long hole / Hole diameter: 3×20 long hole / Size: 160×1700 / Plate thickness: 0.8t / Quantity: 2 pieces

Sanwa Punching Industrial is a specialized manufacturer of punching metal, operating under advanced equipment. We provide a comprehensive range of services from punching (punching) processing to leveling and turret punching, and we also offer sales of standard punching metal products. We can accommodate various requirements such as material, thickness, hole diameter, open area ratio, and flatness, establishing a wide lineup including round holes, elongated holes, square holes, and decorative holes. 【Introduction of Punching Metal Processing Example】 ■ Material: Zinc-coated steel plate ■ Punching Pattern: Elongated hole ■ Hole Diameter: 3×20 elongated hole ■ Size: 160×1700 ■ Plate Thickness: 0.8t ■ Quantity: 2 pieces <Processing Details> This time, we used leftover materials to create corner protectors to safeguard the edges of the material. Since we do not have a bending machine, we punched elongated holes at positions that allow for manual bending. Widening the spacing between the holes requires considerable force when bending, but by narrowing the spacing, we make it easier to bend. *For more details about our products and services, please refer to the catalog available for download below "PDF Download."

The hole pattern is special, and it needs to be designed so that the holes connect when arranged. ＜Processing Details＞ It was determined that responding to this pattern with punching processing would be difficult, so we requested processing from a partner company, similar to the previous case. Although there were concerns about distortion compared to the first item, the final result had less distortion than expected and was beautifully finished. ＜Note＞ Providing accurate data in advance will facilitate smooth production. *For more details on our products and services, please refer to the catalog available for download below "PDF Download."

Precision expanded metal and punching metal.

Precision expanded metal and punching metal.

【For inquiries, please visit the official website!】 Proven track record in various industries requiring precision, such as the energy sector, collectors, power supplies, and electrode substrates!

At Nikken Ras Kogyo, we manufacture precision expanded metal and perforated metal that minimizes misalignment during processing. The quality of our expanded metal and perforated metal minimizes issues such as fraying and misalignment during pressurization, and has been adopted in a wide variety of fields that require precision. We accommodate various non-ferrous metals, including nickel and titanium, and can handle orders starting from just one piece. 【Features of Expanded Metal】 - Lightweight due to being stretched and cut from a sheet! - The mesh stands up during processing, allowing for increased surface area. (Rolling processing is also done in-house.) - There are no seams in the mesh, which distributes the applied load, providing strength. - Good ventilation, lighting, and visibility. 【Features of Perforated Metal】 - Lightweight due to being punched from a sheet! - Compared to expanded metal, it reduces the unevenness of the wire mesh surface. - Combines functionality and strength! *For more details, please contact our official website.
