The clay and the right amount of water are used as the main binder of the molding sand, and the sand type is directly formed and poured in a wet state. Wet casting has a long history and is widely used. The strength of the wet sand depends on the clay slurry in which the clay and water are mixed in a certain ratio. Once the sand is mixed, it has a certain strength. After the sand is made into a sand mold, it can meet the requirements of the combination and casting. Therefore, the amount of clay and moisture in the molding sand are important process factors.
A casting method in which a molding sand is made of a molding sand and a core sand as a molding material, and a liquid metal is filled under a gravity to produce a casting. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the molds are easy to manufacture, and can be adapted to single-piece production, batch production and mass production of castings. For a long time, it has been the basic process in casting production.
