A granular refractory material used in the production of foundry sand and core sand. In the case of using clay as a binder for the sand, approximately 1 tonne of new sand is required for every 1 tonne of qualified castings produced, therefore the largest amount of casting sand is used in sand casting production.

Sand mold casting is a mixture of ordinary fine yarn for the mold, using materials such as steel alloys, aluminum alloys, copper alloys, zinc alloys, glass and so on. After melting the material poured into the sand mold, condensation mold can be, suitable for medium, large or very large castings.

Sand casting, as the name suggests, is a method of casting in which castings are produced in a sand mould. sand casting is the more common casting process in foundry production, mainly using wood or other metal materials to make casting moulds, and then resin sand grains are placed in the mould to complete the core, followed by melting and forming, cleaning, heat treatment, etc., so that the finished sand casting parts can be obtained.

sand casting is a metal casting process that uses sand as the modeling material. A factory specializing in sand casting is generally called a foundry. In the world, the castings produced by sand molds account for more than 80% of the castings produced by various casting molds.
