伸和精工 Company Profile

Town factories that continue to respond with accumulated technology and a unique production management system.

Shinwa Seiko Co., Ltd., located in Ube City, Yamaguchi Prefecture, is a machine processing factory specializing in machining within 300mm. We excel in processing items within 50 to 150mm square, and we produce both round and square items, from single-piece custom matching processing (general-purpose) to new production in medium lots (around 1,000 pieces). Additionally, we routinely handle machining precision tolerances of about H7, and with the newly introduced cylindrical grinding machine, we will be able to offer even higher precision products for round items. The introduction of the cylindrical grinding machine allows for external diameter grinding of work sizes up to φ200×400(mm), enabling the processing of hardened products (HRC 50 or higher) and difficult-to-cut materials that were previously impossible with cutting methods. We have also introduced various 3D printers to propose solutions for the manufacturing challenges of "lightweighting" and "cost reduction" through our "3D printing + precision finishing processing solution."
