The application of iron mold sand coating process for mass production in China began with single cylinder crankshaft. After years of development, the scope of application has been expanding. In addition to castings such as crankshaft, camshaft, balance shaft, valve body, shell and steering knuckle, it has also been applied to castings such as grinding ball, brake drum and wheel hub in recent years. In addition, it is also used in the production of large castings, such as marine crankshaft with a length of 2200mm and a mass of 550Kg, which further widens the application field of iron mold sand coating process.
The iron mold sand coating process production line has also developed from simple machinery to mechanization. The molding qualification rate of film coated sand produced by mechanization can reach more than, and the product qualification rate can reach more than. It has the advantages of high production efficiency, high casting quality, environmental protection and low consumption. Therefore, the mechanized and automatic iron mold sand coating production line will be adopted by more enterprises.
