ABSTRACT:
For the purpose of separating castings from the sand or similar material forming a string of moulds, each of the castings proper together with a lump of heat damaged mould material totally surrounding the casting is separated from the mould string. After having been subjected to an appropriate degree of cooling, the castings are separated from the lump material which, after sufficient regeneration, may be re-used together with the non-damaged material of the moulds.
