Abstract

According to the prior art, through-holes in components are often introduced after the production (casting) of the component. This entails additional outlay in terms of time and equipment. The time required can be considerably shortened if a casting mold is designed in such a way that the through-hole is at least in part formed by corresponding projections being formed on the inner wall and/or the outer wall of the casting mold.
