Abstract: A method to produce a molded part having at least two regions of different strength using a press-hardening tool. A heated blank is formed in the tool during a forming step and held therein for heat-treating during a cooling step. At least one region of lower strength is cooled more slowly than at least one region of higher strength. During the forming step, the entire blank is in contact with a molding surface of the tool. Then, the tool surface is changed such that one or more regions of lower strength have no tool contact during the cooling step. The tool surface associated with the one or more regions of lower strength is provided by tool segments that are adjustable relative to the remaining tool surface. The molding surface of the one or more tool segments is larger than the region of lower strength associated with such tool segment.
