Significant cost reduction compared to forged products! The 200℃ endurance is twice that of commercially available products.
The "IC-EX2" is a mold for CFRP molding (autoclave). Our developed low thermal expansion cast steel can flexibly accommodate complex shapes due to the casting process. Since it overcomes the challenges of low mechanical properties, which is a weakness of cast steel, it holds great potential as a mold for precision CFRP molding with excellent mass production capabilities. 【Features】 ■ Improved strength: Increased mold lifespan ■ Cast steel: Significant cost reduction compared to machining from forged steel ■ Cryogenic treatment + annealing ■ 200℃ strength is twice that of commercial products *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our company started in 1949 as a special steel manufacturing company in Kawagoe City, Saitama Prefecture. During this time, we have supported the foundation of Japanese manufacturing as a proposal-based special steel manufacturer, developing metal materials tailored to our customers' needs. Our main product, low thermal expansion alloys, can adjust the coefficient of thermal expansion from zero to 1 ppm. By developing alloys that meet our customers' diverse needs, such as corrosion resistance, machinability, and rigidity, we possess a wide range of low thermal expansion alloy materials and can recommend and provide materials that are suitable for your use.
