Properties of Molding Material Dry Strength - ` It is the strength of the molding sand in dry conditions. ` When the molten metal is poured in the mold, the sand around the mold cavity is quickly converted into dry sand as the moisture in the sand evaporates due to the heat of the molten metal. ` At this stage the molding sand must posses the sufficient strength to retain the exact shape of ...
