  • Molding Sand Types and Properties PDF

    Molasses sand is a small casting and core making sand which consists of molasses for that reason this sand is termed as Molasses Sand. It provides them with the strength to bear the molding process of the sand. Bentonite and clay help the sand to hold this cohesiveness property. Insufficient strength might be the cause of the collapse.

    Sand is packed around the pattern to form a mold impression. This is much like making footprints on wet beach sand. In fact a rough casting could be made by pouring plaster directly into the impression in the sand. After the mold is packed the pattern is removed and molten bronze is poured into the finished mold to form the casting.
