Sand casting, is a metal casting process characterized by using sand as the basic mold material in which metal is poured. Approx 70% of all metal castings are produced using various types of sand casting process.
Sand casting is relatively cheap and in combination with the appropriate binder system excellent for higher temperature materials including steel and stainless steel. The sand is typically contained in a system of frames or mold boxes known as a flask. The mold cavities and gate system are created by compacting the sand around models, or patterns. Once the pattern is removed the cope and drag are placed together, clamped the metal can be poured into the molds.
