1. A method for producing a profiled component, comprising:
providing and/or producing a profiled structural part;
heat treating the profiled structural part; and
press hardening the profiled structural part in a press-hardening tool,
wherein, during a cooling phase of the press hardening of the profiled structural part:
in a first time phase of the cooling, placing the press-hardening tool into a first physical configuration such that at least one first subregion of the profiled structural part has tool contact with tool parts of the press-hardening tool and is cooled and/or quenched by the tool parts, and at least one second subregion of the profiled structural part has no tool contact with tool parts of the press-hardening tool, and
in a second time phase of the cooling following the first time phase, moving at least a portion of the press-hardening tool into a second physical configuration such that the at least one first subregion and the at least one second subregion both have tool contact with the tool parts of the press-hardening tool and are both cooled and/or quenched by the tool parts,
wherein the profiled structural part in the press-hardening tool is cooled in an interior thereof by circulating air, and
wherein during the cooling phase, different material properties are set in the at least one first subregion and the at least one second subregion.
