Abstract

Bei einem Verfahren zum Endformen eines aus einem im wesentlichen flächigen Halbzeug gebildeten Bauteils, das zumindest eine Schicht aus metallischem Schaumwerkstoff aufweist, wobei das Halbzeug durch einseitige oder beidseitige Formgebung in ein dreidimensionales Formhalbzeug umgeformt wird und anschließend in eine Aufschäumform eingebracht und darin aufgeschäumt wird, wird das Formhalbzeug vor Einbringen in die Aufschäumform zumindest einseitig bereichsweise mit einer reflektionsmindernden Beschichtung versehen.In a method of final forming one from a substantially flat one Semi-finished component formed, the at least one layer of metallic Has foam material, the semi-finished product by one-sided or shaping on both sides into a three-dimensional semi-finished product is then placed in a foam mold and in it is foamed, the semi-finished product is introduced into the foaming mold at least on one side in some areas with a reflection-reducing Provide coating.
