A new material with high rigidity and low thermal expansion! The integrated molding through casting significantly reduces processes such as machining and assembly.
This material is a new substance developed as a high-grade version of mineral casting, applying and advancing the material development and manufacturing technologies of polymer concrete that our company has cultivated over many years. *For details about mineral casting, please refer to the catalog. - Features of this material: 1. It has a rigidity approximately 2 to 3 times greater than that of mineral casting. 2. It is a material with excellent low thermal expansion properties, achieving about 65% of the linear expansion coefficient compared to mineral casting. 3. Like mineral casting, it is a material that can be molded by pouring into a mold at room temperature, providing higher moldability compared to machined products. 【Properties of Hinogranite Material】 1. Static elastic modulus: 97 GPa 2. Linear expansion coefficient: 7.3×10^-6/K (average value in room temperature environment: 10 to 30°C) 3. Density: 3.2 g/cm³

basic information
<Hinogranite> It is a material that applies mineral casting, manufactured by pouring and curing aggregates and resin at room temperature. It has a linear expansion coefficient of 7.3×10-6/K (average linear expansion coefficient between 10 and 30°C) and rigidity equivalent to natural granite, while also possessing high moldability (freedom of shape). By applying it to movable parts that require precision, it enables high accuracy.

Applications/Examples of results
- Expected Application Examples In machine tools and semiconductor manufacturing equipment, even components where space constraints, such as columns, become a bottleneck and mineral casting lacks rigidity can be applied with Hinogranite, which has high rigidity. Due to its small linear expansion coefficient, applying it to machine tables and other components that require high precision can suppress thermal deformation caused by machining heat and temperature changes in the surrounding environment. By using casting for integrated molding, the processes of machining and assembly can be significantly reduced.
