Recent developments in hydroforming technology

Klaus Siegert; Markus Häussermann; Bruno Lösch; Ralf Dipl Ing Rieger

Abstract This paper shows an overview about possibilities of hydroforming sheet metal as well as hydroforming tubes and extrusions. Coming from the deep drawing process with rigid dies, specially designed dies for presses with multipoint cushion systems required for hydroforming sheet metal are discussed. Further special press systems for presses with high ram forces are shown.
