Sand molded casting, also can be referred as sand casting, is a common metal casting process characterized by using sand as the mold material. Sand mold casting is a widely used in forming of casting. The main advantage of sand molded casting is that it is relatively cheap and sufficiently refractory even for steel foundry use. It’s a fact that over 70% of all metal castings are produced by sand casting process.

In sand casting, a pattern of the finished part is placed in sand. The sand is then packed around the pattern to form the mold. If the pattern must be removed before pouring the metal, the mold will be made in two or more pieces. The mold must be modified to include a hole through which the metal will be poured. The mold remains in tact until the metal has solidified. The mold is destroyed when the part is removed, so a new mold has to be made for each casting. Sand casting service companies can cast large parts. Sand molds can be used in iron casting, bronze casting, brass casting, and aluminum casting.
