Disclosed is a forming system having a first die assembly and a second die assembly with dies having die surfaces that are configured to cooperate with each other to form a die cavity therebetween so as to receive a workpiece therein. One or both of the dies includes a heater insert member that has a serpentine groove therein for receiving a flexible heater member. The flexible heater member is configured to conform with the shape of the serpentine groove. The heater insert member is position adjacent to the die surface and provides more uniform heating of the surface to form complex 3D surfaces with tailored properties.

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.
