Sand Casting is made of clay-bonded sand as a molding material. It is a process method with a long history. It is also the most widely used process method. In the development of various chemical bonding sand, the clay wet sand is still the most important molding material, and its application range is wide and the consumption is large, and it is not comparable to any other molding material. It is reported that in the steel castings of the United States, more than 80% of the clay-wet molding sand is used; in Japanese steel castings, more than 73% of the clay-wet molding sand is used.
