Amagasaki Factory

Amagasaki FactoryOur technology of hardfacing weld has a top -level status in Japan• Hardfacing WeldSince our inception,welding technology has always been our core technology and what we do best. This technology involves more than just metal bonding, since hardfacing also plays an important role. Hard-facing is a technique used to give metal materials various functions and applications during the weld-ing process. OFIC has always worked to precisely meet the increasingly advanced welding needs of users. These needs include technologies such as automatic hardfacing welding, reverse-polarity soft plasma welding that minimizes the weld penetration into the workpiece material, and Powdered Plasma Transferred Arc using powders containing insoluble carbides. Our welding technologies have been rated as some of the most advanced in Japan. Cart-loaded heat treatment

This production base for thermalspraying leads our generationin new technical development

Senboku Factory

Thermal spraying is a surface covering and treat-ment technique that deposits a film of melted materi-als such as ceramics, cermets, metals or resins onto a surface material to make it more wear- heat- or corrosion-resistant, or improve properties such as electrical insulation. Widely used in industrial fields requiring advanced functions, thermal spraying is used to make products such as communication satellites, high-rise steel structures, industrial machinery parts, electronic devices and consumer appl iances. Senboku Factory special izes in advanced thermal spraying technologies, and assists Amagasaki Factory as a major production base for large products manufactured with thermal spraying.

This manufacturing base has contributed forour steel business’ growth in East Japan

Omigawa FactoryIn 1969, Omigawa Factory moved to a massive site of around 22,000 square meters that OFIC had acquired in Chiba’s Omigawa Industrial Park which located in Chiba Prefecture . After initially working on pressure vessel fabrication and overlaying, the site steadily expanded its activities by constructing a specialized machining plant, a plant for large roll overlaying and large pressure vessel fabrication, and a thermal spraying plant. In 2004, Omigawa Factory installed technology for manufacturing small forged hardened steel rolls.

Our equipment for special induction hardening provides high-quality rolls by their performance of high hardness and depth• Small forged hardened steel rollsOmigawa Factory started the manufacturing of small forged hardened steel rolls in January 2004 after installing heat treatment equipment acquired from Kanto Special Steel Works that was formerly a lead-ing provider and adopting its hardening technology. The new equipment ensures more stable quality, letting the factory provide rolls with new levels of quality and performance that draw on the many ben-efits of induction hardening equipment.
