Abstract
In a method of producing a hardened formed part, in particular for a structure or body part of a motor vehicle, a metal blank is heated and then hot formed in a cavity of a thermoforming mold to produce a formed part. The formed part is hardened in the cavity of the thermoforming mold through contact with a coolant fed into the cavity via feed channels, whereby a state of aggregation of the coolant is adjusted or the coolant is maintained at a pressure above the steam pressure.
