  • Properties of Moulding Sand in Casting - .

    The ability of moulding sand to behave like a fluid when it is rammed is called flowability. Due to this property, the sand can easily occupy the space in molding box and take up its shape. This allows the sand to compress to a compact density and let it pack around the pattern. The sand should be of high flowability, so that it can be easily compacted for uniform density and to obtain a good ...
