Company information
Since our establishment in June 1947, we have consistently engaged in the manufacturing and sales of electromagnetic steel sheet cores. The SA and SB type cores, which we developed and commercialized, were eventually established as JIS standards and are widely distributed as standardized products not only domestically but also overseas. Please feel free to contact us if you have any inquiries.
