What is sand casting?
Sand casting is a casting method to produce castings in a sand mold. Steel, iron, and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, and mold manufacturing is simple, it can adapt to the single-piece production, batch production, and mass production of castings. It has been the basic process of casting production for a long time.
