On the basis of production experiences of iron castings, the quality requirements of castings for Japan were analyzed from two aspects, internal and appearance quality, which fully illustrated the high quality requirements of Japanese for castings and their strict attitude towards work. These are worth learning for domestic foundry men in quality control of cast iron product. Source

On the cylinder opening wall of the 462Q cylinder body after finishing machining, the non-uniform black spot appears and that results in approximately 15% rejection of the cylinder body. In order to solve this problem, the reasons were analyzed, such as raw material, the chemical composition, the cooling condition and so on. Finally, the sunspot in cylinder hole was eliminated by a series of measures such as changing the chemical composition and the pouring temperature, as well as the adjustment of charging proportion and so on.
