Our company has developed two types of heat-resistant cast steel: "Austenitic 1,050°C compatible material" and "Ferritic 900°C compatible material," which excel in heat deformation resistance, crack resistance, and oxidation resistance. With the reduction of exhaust emissions and improvement in fuel efficiency, the exhaust temperatures of gasoline vehicles are on the rise. By utilizing our material development technology for castings, we have added heat resistance that can be used in such high-temperature environments, and by combining this with thin-walled technology, we have also achieved weight reduction of components. **Features of Austenitic 1,050°C compatible material:** - Developed based on the conventional standard material "DIN 1.4848 [SCH22]." - Optimized the alloying elements added to achieve heat resistance capable of withstanding 1,050°C environments. **Features of Ferritic 900°C compatible material:** - Developed based on the ferritic stainless steel "SUS430 J1L." - Optimized the alloy composition and reviewed the casting and heat treatment processes to achieve excellent elongation properties. *For more details, please refer to the materials.

The composite technology of aluminum castings and iron (cast iron) ensures the necessary strength while enabling weight reduction of the products. Additionally, by applying molten aluminum plating to the iron core material, the corrosion resistance performance can also be significantly improved.

We will develop new materials and customize materials according to our customers' needs. We propose original materials and support the enhancement of the added value of the products our customers are developing. Whether it is cast iron, aluminum castings, or cast steel, we provide consistent support from alloy design to the investigation of a wide variety of property values. It is also possible for us to industrialize and supply the developed materials.

Hinode Holdings Co., Ltd. and Hinode Water Supply Equipment Co., Ltd. have jointly developed the high-rigidity aluminum casting alloy "ATHIUM" in collaboration with Makino Milling Machine Co., Ltd. and Tajima Light Metal Co., Ltd. In this joint development, we utilized the technology cultivated in the material development of manhole covers to research methods for controlling the metal structure to achieve high rigidity in this product, and by optimizing the chemical composition, we realized a high-rigidity aluminum casting alloy that has not been seen before. We anticipate its adoption in various industries that require high rigidity (lightweight) and positional control accuracy, such as machine tools, industrial robots, semiconductor equipment, inspection equipment, and automobiles. 【Features】 - Young's modulus improved by 40-60% - Reduced deformation caused by constant loads and inertial forces during acceleration and deceleration, leading to improved positional control accuracy - Parts that do not become products (such as sprues) can be re-melted as raw materials - No waste is generated, combining ease of recycling with economic efficiency *For more details, please refer to the PDF document or feel free to contact us.

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!

"Mineral Casting" is a polymer concrete that solidifies aggregates with resin, featuring high damping properties, low thermal conductivity, and electrical insulation. By adopting it in machinery, high levels of damping can be achieved, and through a hybrid structure that fills a cast iron frame with mineral casting, it can also achieve high rigidity equivalent to cast iron. [Features] - Approximately 10 times the damping performance compared to cast iron (FC300), about 1/30 the thermal conductivity, and high electrical insulation - Significant reduction in manufacturing processes by incorporating insert nuts, grounding wires, coolant pipes, etc. (total cost reduction) - No melting process, greatly reducing CO2 emissions - High-precision transfer technology (0.003 to 0.007mm/1000mm) reduces costs through processing-free methods - Purely domestically produced with stable supply (production line with a capacity of 2000t/year will be fully operational from April) - Maximum size of 3,900×3,100mm, height of 4,000mm, and capable of handling up to 15t *For more details, please refer to the materials.
