Product Details:
Green sand is the cheapest molding material worldwide, so causes the lost production costs for iron castings. 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). Based on the casting material, there are three main types of sand: silica-based, chromite-based or zircon-based.
