Merchandised products within the field of micro-technology as well as research activities show an important demand in complex shaped tubular micro-components, for example for medical devices, micro-fluidic or micro-mechatronic applications. Concerning such microcomponents made from metal materials, manufacturing techniques for the economic mass production of adequate tubular parts are often missing. Hydroforming, as a proven technology in mass production of conventional sized tubular components, e.g. for automotive applications, offers miscellaneous advantages also for the manufacture of hollow shaped micro-parts. Against this background, a micro-hydroforming system has been developed, capable for series production, and experimental and theoretical investigations into this new technology have been carried out. Results of latest research are presented concerning the configuration of tools and machines, optimised with the aid of the Finite Element Method to improve the produced component accuracy.
