Darville casting is especially effective for large castings. By inclining the pouring, it is possible to cast quickly while suppressing turbulent flow of the molten metal, less impurities such as oxides are mixed in compared to general gravity casting, and it is possible to cast good quality ingots and large castings.

General industrial parts are required to have characteristics for all applications. We recommend materials that match those characteristics and utilize all equipment such as sand casting, continuous casting, centrifugal casting, we support a wide range from small parts to large one for power plants, large sluice gates, pump bearings, gears of machine tools and industrial machinery.

Since it is manufactured by continuous casting instead of sand casting, there are few defects and the quality is stable. Not only round bars and pipes, but also hexagonal and octagonal continuous casting are possible. They are used as faucet fittings in residential and industrial facilities. In addition, in order to respond to the strengthening of water quality standards for tap water, we also manufacture continuous castings of lead-less bismuth-based bronze “Aqua Bronze,” which we have developed in-house.

We manufacture propellers and shaft sleeves for ships that require high safety and corrosion resistance by large sand casting and centrifugal casting. Since corrosion resistance is important for long-term voyages, in addition to bronze, aluminum bronze which has excellent corrosion resistance to seawater is often used.

At the same time that the first continuous casting machine for steel was Installed in Japan, we started manufacturing the copper mold. Copper molds with high thermal conductivity are applied to the continuous casting machine, and our molds are widely adopted by blast furnaces, electric furnaces and special steel manufacturers in Japan and overseas. In addition to continuous casting machines for steel and non-ferrous metals, we also manufacture pure copper as a mold for special steel and magnetic materials, in-house developed precipitation hardening materials, and low-conductivity materials for electromagnetic stirring. Our mold achieves high quality and long life by being manufactured by free forging, and has established itself as the largest mold maker in Japan. We also support the design of optimal cooling structures by thermal analysis and the production of assemblies including jackets.
