Q. Explain the Cushion Materials which used in moulding sand?

These materials when added to the moulding sand burn and from gases when the molten metal is poured into the mould cavity. This gives rise to space for accommodating the expansion of the sand at the mould cavity surface. Wood flour, cereals, cereal hulls and cellulose etc. discussed above are called as 'Cushion materials'.
