Sand casting - Wikipedia

Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.Over 60% of all metal castings are produced via sand casting process.

Metallurgical Terminology Glossary | MetalTek

Sand. In metalcasting, a loose, granular material high in SiO2, resulting from the disintegration of rock. The name sand refers to the size of grain, and not to mineral composition. Diameter of the individual grains can vary from approximately 6, to 270 mesh. Most foundry sands are made up principally of the mineral quartz (silica).
