Abstract
A casting device having a casting mold and a core for producing a helical casting is described. The may have an expendable core that can be dissolved after the casting process. Advantageous effects of the device and process can be achieved by virtue of the fact that the female mold for accommodating the helical casting during the casting process is formed completely within the outer contour of the core, the female mold being delimited by the core and, at the peripheral boundary surfaces of the female mold, by the casting mold.
