Abstract

A method for producing a cast workpiece includes the following method steps: providing a mold having at least one mold core arranged in the mold; inserting a metal melt into the mold; waiting for a period of time until at least the outer contour of the metal melt has solidified and the workpiece has been formed from the metal melt; removing the workpiece from the mold; shattering the mold core, wherein this method step is carried out before the workpiece has entirely cooled down from the casting process. For shattering the mold core, a hammer head is applied on a defined energy transmission surface of the workpiece and the energy transmission surface is acted on, in particular hit on, by the hammer head.
