Factory features

A key factory for supporting the production of power- and labor-saving machines and tools of the Nitto Kohki Group.

From cutting, polishing, exfoliation, drilling, to chamfering of steel materials, Nitto Kohki Group’s machines and tools are used in various processing factories. Medotech Co., Ltd., as a main factory, manufactures an extensive range of products using an air pressure, electric motor, and oil pressure as a driving source. Under the slogan of “People-oriented technologies”, Medotech challenges an unalterable theme of satisfying both increased power and miniaturization in the pursuit of manipulation performance, safety, design, and environmental consciousness.

Our ability to make improvements leads to increased productivity by capitalizing on a wealth of mechanical equipment.

Our factory is equipped with nearly 170 machines and tools, including machining centers, NC lathes, and NC grinding machines, and uses an integrated system from parts processing and product assembly to inspection, packing and shipping. To ensure the management using the concept of 5S (Seiri, Seiton, Seisou, Seiketsu, and Shitsuke) at a high level, we have implemented the C-TPM activities on an ongoing basis since 2005 to carry out improvement activities. With our ability to make improvements, we devote ourselves to raise the level of quality, faster delivery timeline and reduced costs.
