Nitriding of cutting tools is possible! We recommend composite hardening treatment using atom nitriding and PVD coating!
Metal nitriding refers to a treatment that diffuses nitrogen atoms into the metal to improve surface hardness, with the expectation of extending the service life by 2 to 3 times. "Atom Nitriding" is an innovative technology for plasma nitriding. In general nitriding methods, it is difficult to avoid the formation of a compound layer, necessitating the grinding removal of this layer. However, since tools and molds have complex shapes, grinding removal is challenging. This technology forms only a tough diffusion layer without creating a compound layer. 【Features】 - The nitrided surface consists only of a diffusion layer: the finished surface has good roughness and maintains gloss. - Nitriding is possible in narrow slits and fine pores. - Nitriding of cutting tools is possible. - The release properties of resin molds are improved. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Suzusho Co., Ltd. was founded in 1955 as a metalworking company in Nakatsugawa, Gifu Prefecture. Later, it also started operations as a machinery and tool trading company, embarking on a genuine journey closely connected to the local community and the manufacturing industry. As it grew and developed alongside the industrial changes in Nakatsugawa, it has now established a solid track record as a "comprehensive trading company for production technology" in the Gifu Prefecture and the southern Shinshu/Kiso area of Nagano Prefecture. With reliable experience since its founding, we are committed to supporting local communities and, by extension, Japan's manufacturing industry with safety and trust, continuing to grow together with our customers.
