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 machinery 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 machines, 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 that can flexibly respond to fluctuations in production volume, from a minimum of one piece in small lots to large lots. *Development of new materials and customization of materials according to customer requests are possible! Please feel free to contact us.
