For those struggling with the procurement of large pump impellers and bearings! We solve this with 55 years of processing experience for heavy industrial equipment, ensuring reliable infrastructure maintenance.
"Are you looking for a reliable outsourcing partner for custom parts of rotating machinery, such as turbine and compressor shafts, and agitator shafts, which require high precision?" - The piping flanges in the plant are of a special standard that cannot be substituted with commercially available products. - There are few companies capable of handling complex machining of large pump impellers, sleeves, and rotor bearings. - Important components like rolls and couplings in steelmaking equipment are constantly exposed to high pressure and high temperatures, raising concerns about quality. Iwai Koki, which has supported infrastructure facilities in Futtsu City, Chiba Prefecture for many years, will fundamentally solve these challenges. 【Technical Features (Three Strengths)】 - High proficiency in rotating bodies and shafts: Precision machining of round parts such as agitator shafts and rotor bearings, which require centering and coaxiality. - Small-lot machining of custom piping flanges: Manufacturing of non-standard large-diameter flanges and special rings, whether welded neck type or blind type, starting from just one piece. - Expertise in tough materials for steelmaking and chemical equipment: Extensive know-how in processing metals used in harsh environments, including special steels, difficult-to-cut materials, and high-strength castings. *For more details, please download the catalog or feel free to contact us.
