Our features We are a specialized manufacturer of forged materials for various flange joints and ring-shaped machine parts. We make full use of various construction methods such as free forging, stamping forging, and rolling forging. It is an agile system that responds to drastic changes such as small quantity, high variety, and short delivery time. It has been evaluated and trusted by all parties as a certified factory for manufacturing marine materials for LR, NK, DNV, and KR. New equipment We have newly introduced a band saw machine for ring cutting. This makes it possible to meet the demand for thin-walled rings, which was difficult to roll in the past. ｜Company Information｜Product Information ｜Quality Control｜Inquiries ｜Links｜
