Clay and an appropriate amount of water are used as the main binders for the molding sand. After the sand mold is made, it is directly assembled and poured in a wet state. This is called a clay wet sand mold. This type of sand mold is easy to manufacture, low in cost and widely used. For the clay dry sand mold, after the sand mold is made, the surface of the mold cavity is coated with refractory coating, and then placed in a drying furnace for drying. After it cools down, it can be assembled and poured. The chemical hardening sand mold is a sand mold that uses a chemical hardener to harden the molding sand.
