Sand Casting Aluminum

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 Process, Defects, Design

Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate. The sand casting process involves the use of a furnace ...
