Low thermal expansion material "Hino GD Invar" with excellent casting defect suppression and machinability.
Stable supply available from one unit to large lots! We have a track record of delivery in various industrial machines such as semiconductor manufacturing equipment, machine tools, precision measuring instruments, and vacuum pumps.
The "Hino GD Invar" is a low thermal expansion material that achieves unprecedented stability in low thermal expansion, castability, and machinability through the optimization of alloy components and heat treatment. It has a proven track record in various industrial machinery, including semiconductor manufacturing equipment, machine tools, precision measuring instruments, and vacuum pumps. 【Features】 ■ It has a low thermal expansion coefficient α = 1.0 to 3.5 ppm/K (average 20 to 50°C). ■ Castability/Machinability: By optimizing the alloy structure, it suppresses casting defects and excels in machinability compared to nickel-based materials. ⇒ It is ideal for parts with complex shapes or those prone to casting defects, as well as for parts that require machining. ■ The automatic molding line for sand molds enables the production of a wide variety of small quantities and stable supply. ⇒ With an automatic pattern change system, we have an automated and efficient sand mold automatic molding line, allowing us to flexibly respond to changes in production volume from a minimum of one piece to large lots. * We can develop new materials and customize materials according to customer requests! Please feel free to contact us.
