Abstract

An apparatus (10) for forming a void or voids in a casting during a casting process comprises at feast one body (12) comprising a substantially continuous outer surface, the body (12) formed such that the outer surface can be penetrated, with the original shape of the body (12) substantially retained when penetrated, and a penetrating and securing means (3), configured for positioning in a casting mould and configured to penetrate the at least one body (12) to secure the at least one body (12) to the penetrating and securing means (3) to retain the body (12) in position.
