Green Sand

Green Sand

Green sand is a widely-used and cost-effective metal casting process. It involves the use of naturally bonded sands known as "green sands." The process begins with wet sand screening to remove impurities followed by mixing the sand with clay and water additives. The prepared green sand is then poured into sand boxes or molds and compacted through tamping or jolting. Liquid iron is finally poured into the molds, which solidifies as it cools.
