Abstract
A permanent mold can include mold halves which can be joined together on a mold separation plane. The mold halves of the permanent mold are joined together such that the permanent mold has a cavity, which defines the shape of the helix or the shape of a bent-up helix, when the permanent mold is joined together. The specified helix or the bent-up helix has a flattened profiled winding cross-section which has two opposite flat faces, an outer face and an inner face opposite the outer face. The mold separation plane runs at least partly along the flat faces from the inner face to the outer face, wherein the permanent mold has a bulge which extends along the mold separation plane and protrudes into the cavity at least in a region in which the mold separation plane runs along one of the flat faces such that the cast body is provided with recesses on the flat faces.
