  • Permeability (foundry sand) Wikipedia

    OverviewAffecting factorsSignificanceTesting procedure

    Permeability is a property of foundry sand with respect to how well the sand can vent, i.e. how well gases pass through the sand. And in other words, permeability is the property by which we can know the ability of material to transmit fluid/gases. The permeability is commonly tested to see if it is correct for the casting conditions.

  • Sand Casting For Manufacture

    Dry Sand Molds: Dry sand molds are baked in an oven, (at 300F 650F for 8-48 hours), prior to the sand casting operation, in order to dry the mold. This drying strengthens the mold, and hardens its internal surfaces. Dry sand molds are manufactured using organic binders rather than clay.

  • No Bake Foundry Airset Molding

    The airset molding method is also referred to as no bake molding, making AFW a no bake foundry. The use of Silica sand, which is chemically bonded with resins or binders, versus naturally bonded sand lends certain casting benefits.
