ABSTRACT:
An apparatus and method for producing one or more hollow sand cores suitable for casting moulds using a bipartite core box defining a mould cavity into which sand and a catalyst or a curing agent are introduced. The method includes the steps of establishing a pressure gradient which decreases from the interior to the exterior of a non-heated core box of porous material; introducing sand and a catalyst or a curing agent into the mould cavity defined by the non-heated core box; and directing the introduced sand and catalyst or curing agent against the interior surface of the non-heated core box, which step of directing, at least in part, is obtained by the pressure gradient established between the interior and exterior of the non-heated core box. The apparatus provides structure for accomplishing the above described method.
