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.
