Types of Moulding Sand - Learn Mechanical Engineering

2021-11-12  The mould should disintegrate into small particles of moulding sand with minimum force after the casting is removed from it. 7. Refractoriness: Refractoriness is the property of sand to withstand high temperature of molten metal without fusion or soften. Moulding sands with poor refractoriness may burn when the molten metal is poured into the ...

Molding Sand: Types and Properties [PDF] - Learn

Green Sand: The green sand is tempered sand and contains enough amount of moisture. Greensand contains a mixture of 15% to 20% of clay, 6% to 8% of water and silica. Strength depends on the mixture of water and clay. The mixture acts as the bonding material in the sand. Greensand mold is that mold which is basically made from Green Sand.
