Sand Casting Aluminum - Fab Central

Sand casting aluminum with a charcoal furnace. Sand casting is the process of casting molten metal into a mold cavity formed in sand. There are really only two basic requirements: that the sand has a cavity in the shape of the object you wish to cast, and that there is a channel you can pour metal into that will lead to the cavity.

Sand Casting Metal Casting Resources

Jan 25, 2019  Sand casting is one of the few available processes for metals with high melting temperatures such as steels, nickel, and titanium. Because of its flexibility, heat resistance, and relatively low cost, sand casting is the most widely used casting process. Castings are produced by pouring liquid metal into a mold cavity.

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.
