We handle energy, IT, chemical/bio and food related special products, with strength in metal bonding by diffusion bonding. We conduct integral acceptance inspection of members through assembly, bonding, inspection, packing and delivery. Diffusion bonding laminates and bond members to create complex components and parts which have been impossible to create by cut processing and machining. In addition, we work on diffusion bonding technology for various materials, and thus can respond to bonding of not only stainless steel in general but also aluminum alloy, nickel alloy, copper, titanium and other materials.
