What Is Sand Casting?

The production of metal parts requires a metal casting process that can mould the metal into virtually any shape. The sand casting process is a direct, versatile and cost effective option for producing metal components in foundries, but what is sand casting?

Sand casting is a metal casting process that uses sand as the mould material. In sand casting, the mould is formed around a pattern by ramming sand, mixed with the correct binder, onto the pattern. The pattern is then removed, leaving a cavity in the shape of the casting to be produced. If the casting is to have internal cavities or undercuts, sand cores are used to make them. Molten metal is poured into the mould and when it has solidified, the mould is broken to remove the casting.
