Sand casting, also known as sand molded casting, is a metal casting process, also called as casting in China in Connect characterized by using sand as the mold material. The term “sand casting” can also refer to an object produced via the sand casting in China process. Sand castings are produced in specialized factories called foundries. Over 70% of all metal castings are produced via sand casting process, also casting parts in China.

Sand casting is relatively cheap and sufficiently refractory even for steel foundry use. In addition to the sand casting parts in China, a suitable bonding agent (usually clay) is mixed or occurs with the sand. The mixture is moistened, typically with water, but sometimes with other substances, to develop the strength and plasticity of the clay and to make the aggregate suitable for molding. The sand casting in China is typically contained in a system of frames or mold boxes known as a flask. The mold cavities and gate system are created by compacting the sand around models, or patterns, or carved directly into the sand.
