Abstract: A method for hot forming a semifinished product in sheet form for a motor vehicle component. The method includes heating the semifinished product to be formed in a heating process and forming the heated semifinished product in a shaping forming process. During the heating process the semifinished product undergoes an input of heat from at least one heat source. During the heating of the semifinished product, a shielding device is arranged between the heat source and the semifinished product, such that the semifinished product is thermally shielded at least in certain portions in such a way that a first semifinished-product portion is heated differently than a second semifinished-product portion.
