Castings are produced by sandwiching a central mould part 10 between two outer mould parts 36, 38 during the casting process. The central mould part 10 is then transfered sequentially from between the outer mould parts 36, 38 and subsequently re-located between the outer mould parts in a vacant, relatively cool, and dry condition for the production of a further casting. In one embodiment a plurality of central mould parts are transferred sequentially from the outer mould parts to a removal station 45, a quenching station 50, and a drying station 70, before being returned to the central mould parts.
