Company information
Our company was founded in 1887 (Meiji 20) in Seto City, Aichi Prefecture, a town known for its ceramics industry, as Yamato Ceramics. In 1957 (Showa 32), we relocated to our current location as Maruwai Yano Ceramics Co., Ltd., where we conducted further research on product materials and molding methods, leading to the production of items such as firing tubes, electric resistance bobbins, and insulators. Furthermore, we offer a variety of materials to meet all industrial needs, including alumina, magnesia, steatite, mullite, cordierite, silicon carbide, silicon nitride, and zirconia. In response to the increasing demand for ultra-high temperatures, we manufacture heat-resistant and insulating parts for industrial and household equipment, including insulators for electric heaters, using various materials.
