1 Policy neis challenges new capabilities of joining technology through intensive research and development for new ways. neis co.,ltd 1.Specialty Welding / Brazing Consumables Outline: Company name neis co.,ltd. Established Jan Capital 150,000,000. Headquarters 20-1 Kitadaimotsu-cho Amagasaki-city Hyogo Pref. Certified: ISO 9001 Vacuum Brazing Factory ISO14001 Headquarters & Factories Nippon Kaiji kyokai (NK) Mitsubishi Heavy Industries Takasago Plant for ASME Hitachi,Hitachi plant, for Welding Fabrication and AlBc Overlay 2.Welding / Brazing Fabrications and Rebuildings A Member of: The Japan Welding Society The Japan Welding Engineering Society The Japan Welding Rods Association Japan Vacuum Industry Association 3.Vacuum Engineering Business Stages: 1. Specialty Welding / Brazing Consumables A supplier of products and technical information 2. Welding / Brazing Fabrications and Rebuildings A welding and brazing contractor. Our welding engineers support customers to maintain industrial equipments and chemical machines made of special alloy materials. 3. Vacuum Engineering A supplier of custom specific vacuum devices and equipments assembled in vacuum furnace or by appropriate joining methods.

2 neis Consumables Sixty years of neis brazing & welding specialty products and technical service have been appreciated by our customers support and reliance. Brazing products: Alloys of Silver, Phosphorus, Copper, Nickel, and for Vacuum filler. Their forms available in rods,wire, strip, paste, sheet(much wider than strip), powder, clad(newly developed), and preforms. FCW for aluminum brazing (new product) Fluxes made for the specific metals, temperatures, and conditions of your brazing applications. Automated Equipment engineered and manufactured to match your production requirements Welding products: FCW of specific use for resistance of corrosion, abrasion, erosion, and heat as well as specific use of Electrodes. FCW:GC2Z is widely applied for Zn dip- coated tubes and plates in piping and shipbuilding industry. neis consumables Flux cored Aluminum wire, Alu 19 FCW Aluminum ring preforms Automated equipment of Aluminum brazing

3 neis Welding / Brazing Fabrication and Re-building More than fifty years actual results of specialty welding performance in the maintenance of plant machinery (blowers, impellers, pumps, rotary feeders, screw feeders, centrifugal separators, mixers, crashers, heat exchangers, large scale valves, and so on) have been appreciated by users high reliance. Our maintenance welding on industrial machines range over in such plants as steel, paper, cement, petrochemical, synthetic resin, oil refinery, copper, aluminum, mining, shipbuilding, automobile, and environment. Our welding performance extends over such diversified procedures as fabrications replaced by higher grade materials, renewals, repairs, build-ups, hard facings, corrosion or heat resistance lining to make life longer and to save cost alike.
