To produce precision castings from a melt, use is made of a metallic casting wheel ( ) which has an annular distribution channel ( ) and a plurality of interchangeable casting moulds ( ), each having at least one filling opening ( ). The melt quantity per casting operation is chosen here such that the casting moulds ( ) and the distribution channel ( ) are filled with the melt upon the rotation of the casting wheel ( ) about its axis (A&mdash;A), in such a way that after the solidification of the melt the precision castings are held together by a ring of the casting material which is formed in the distribution channel ( ), the so-called circulating material for new casting processes, and are removed from the casting wheel ( ) together with the casting moulds ( ), whereupon the precision castings are separated from the ring. In order to be able to produce precision castings with complicated three-dimensional shapes, in particular with undercuts, by this means as well, the casting moulds ( ), which can be used only once and are destructible for the purpose of demoulding, are selected from a ceramic material and are attached in a positive-locking and interchangeable manner to the casting wheel ( ) and so as to protrude therefrom. As a result, the circulating material can be fed uncontaminated to a recycling process.
