Molding Sand: Constituents, Types and Properties

From 10 to 15% of the whole amount of molding sand is the facing sand. 2.5 Green sand. Green sand is also known as tempered or natural sand which is a just prepared mixture of silica sand with 18 to 30% clay, having moisture content from 6 to 8%. The clay and water furnish the bond for green sand. It is fine, soft, light, and porous.SAND, SAND ADDITIVES and SAND PROPERTİES Most green sand molds consist of silica sands bonded with a bentonite‐water mixture. The term green means that the mold, which is tempered with water, is not dried or baked. The composition, size, size distribution, purity, and shape of the sand are important to the success of the mold
