permeability test for moulding sand

  • Permeability (foundry sand) Wikipedia
    OverviewAffecting factorsSignificanceTesting procedurePermeability 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.
