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. WebbSand casting can be produced in a wide range of sizes, from small statues to parts weighing over 100 tons; Very complex parts can be produced easily and in one piece; …
