Abstract

Method for the manufacture of closed, hardened steel sections by hydroforming, a blank being placed in a substantially enclosing forming tool and openings in the blank being closed and connections for hydraulic fluid being provided to the inside of the blank and fluid being pumped into the blank at high pressure so that the blank is deformed according to the forming tool, the fluid being removed and the blank being hardened by heating and subsequent cooling. <IMAGE>
