Nogamigiken Co., Ltd.

Meguro-ku, Tokyo|Design and manufacture of molds and ultra-precision jig


Feature 1: Core Technology During the more than forty years since its establishment, Nogamigiken Co., Ltd. has been engaged in research into precision grinding technology. The knowhow we have accumulated in pursuit of technology for the forming of grindstones used in grinding processes has culminated in the realization of our core technology that features parallel and right-angle precision of 5/10,000mm, unachievable even using currently available the state-of-the-art machines.

Feature 2: One-step Manufacturing from Prototyping to Mass-productionBased on information provided by customers, Nogamigiken Co., Ltd. is engaged in processes ranging from design and development to prototyping. In addition, we also carry out mass-production using precision press processing, enabling us to factor mass-production into processes from design to prototyping.
Applying our specialty of ultra-precision grinding technology to ultra-small precision press processing, we have realized an integrated manufacturing process that ranges from the in-house manufacturing of dies and trial casting to mass-production. Our integrated manufacturing process ranging from prototyping to the manufacturing of dies and production also enables us to respond flexibly to sudden changes in specifications and requirements for shorter delivery times.

Feature 3: History of receipt of Numerous AwardsWe are proud of the various awards we have received during the history of our company.

MessageApplying the knowhow in precision blade manufacturing and in-house mass-production presses it has accumulated during the twenty years since its establishment, Nogamigiken Co., Ltd. is engaged in the design and production of precision-punching jigs and dies. The jigs and dies we manufacture specialize in burr, contamination and deformation-free punching of thin film materials including battery electrode materials (electrode plates and separators) and high-function film. Meeting the need of our customers, to date, we have manufactured more than 3,000 order-made jigs. Unfettered by conventional stereotypes, we meet the wide diversity of needs of our customers ranging from the prototyping level to mass-production lines based on our long years of experience and flexible conceptualization, thus enabling our customers to realize goals such as improved production efficiency and cost reductions.
