In a method for molding a sealing device onto an end fold of a pleated bellows, wherein the end fold comprises an outer side and an inner side, the pleated bellows arranged in a casting shell assembly is embedded in a curable sealing material, limited at a rim of the pleated bellows by a casting chamber formed by the casting shell assembly. Expansion of the curable sealing material is reduced or prevented by a limitation element contacting the inner side of the end fold. A casting shell assembly has top and bottom casting shell parts forming a casting chamber to mold a sealing device onto the end fold of the pleated bellows by a sealing material. The bottom casting shell part has a channel for receiving the sealing material. The channel has an upwardly projecting limitation element for engaging an inner side of the end fold.
