Castings is our core business at Nippon Chuzo. The design of the casting system has a significant bearing on the success of the finished castings. The casting system takes into consideration a number of parameters including the composition of the casting sand, the main mold and core design, the configuration of the runners, the melt temperature and the solidification time. With our longstanding expertise in casting systems, we are able to design and produce a wide range of irregular and specialty shapes and performance castings to a very high degree of precision and purity.

Nippon Chuzo employs LAVD and HSR vacuum degassing pumps to remove oxygen and nitrogen from steel melt, together with an atmospheric adjustable CAC casting system that depressurizes the sandbox or creates vacuum conditions as required. These processes help to minimize the presence of oxides and impurities that lead to pinholes and blowholes. Higher purity means fewer defects and a higher quality product.
