ABSTRACT:
A method and apparatus are shown for improving the collapsibility characteristics of foundry cores and molds after being contacted with a heated, cast product. The foundry cores/molds are contacted with an oxidant impregnating liquid after being formed and prior to contact with the heated, cast product. The heat of the cast product is sufficient to sustain combustion of the chemical coating of the sand particles making up the cores/molds to facilitate removal with a minimum of force after casting.
