Hydroforming, a metal forming process for the production of sophisticated components with complex geometries from mostly tubular semi-finished products, has been successfully applied in some industries for several decades. Particularly, various applications from the automotive sector such as elements of the exhaust system, structural components or drive elements can be manufactured. As trends in tube and sheet metal forming move towards lightweight construction, complex components with low production volumes, and high precision, the prospective expansion into further application areas is anticipated. To enhance the efficiency of the process, additional processes can be integrated into the hydroforming process. Examples of this are punching, collar pulling and other joining processes. Typical components include lightweight camshafts in which the cams are form- and force-fitted onto the tubes within forming process. Despite arbitrary three-dimensional forming and the high degree of flexibility, the hydroforming process is subjected to certain restrictions. Generally, in an industrial environment, only semi-finished products with wall thicknesses from 1.5 mm to a maximum of 3.5 mm are formed. Wall thicknesses of less than 1 mm are common for thin-walled, tubular components. These require special technological measures in the area of toolmaking, particularly regarding sealing system and tool engraving, and are subjected to process parameters with correspondingly smaller process windows
