Abstract
A method for producing a helix includes a step of providing a permanent mold with mold halves which are joined together on a mold parting line. The method additionally has a step of joining together the mold halves of the permanent mold 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, wherein the helix or the bent-up helix has a flattened profiled winding cross-section which has two opposite flat sides, an outer side and an inner side opposite the outer side, and the mold parting line runs at least partly along the outer side and/or the inner side and/or edges of the profiled winding cross-section.
