The advantages of green sand casting process are low price, simple production equipments, can produce various unit weight from 0.1 kg to 500 kg, and various size of castings, also can meet various quantity production requirements. Green sand is a mixture typically containing sand (75 to 85% by mass), bentonite or kaolinite clay (5 to 11%, used as a binder), water (2 to 4%), sludge (3 to 5%, acting mostly as filler) and anthracite (<1%, as a carbonaceous additive).
