Company information
Since our founding in 1938, we have recognized the potential of cemented carbide in industry and have independently pioneered innovations in cemented carbide tools and the evolution of processing. Based on the powder metallurgy technology cultivated in cemented carbide manufacturing, we have successively introduced innovative technologies to the market, including the world's first practical application of conventional cermet chips, the development of ball end mills and drills with spiral cutting edges, and end mills with twisted cutting edges. In recent years, we have created highly original new technologies in various fields, such as diamond and cemented carbide integrated sintered products, cemented carbide for irregular gear forming molds, and tool materials made from rare metal-reduced alloys, which we sell worldwide. In addition to developing materials and products, we consistently conduct in-house production from the preparation of raw powders, ensuring stable high-quality products, which we believe has earned us the trust of our customers. Today, there are very few products in the world that do not undergo machining processes such as cutting or plastic processing. Even in the realm of advanced science, the advancement of processing technology is essential for practical application and industrialization. In this era of global competition, we will challenge new fields without being bound by convention, adhering to the philosophy that "management is creation" and "richly creative technology development" to contribute to the world.
