Abstract
A mold or stamping tool with which a simple, cost-effective stamping or molding in the nanometer range is enabled by a molding or stamping surface layer of the mold or tool being provided with hollow chambers formed by anodic oxidation.
Claims19
Stamping tool with a structured stamping surface, wherein the stamping surface is formed by an anodically oxidised surface layer or covering layer with open hollow chambers created model-free by the anodic oxidation, wherein the stamping surface is structured at least partially in the nanometer range by the hollow chambers.
Mold with a molding face formed of an anodally oxidized surface or covering layer with open hollow chambers created model-free by the anodic oxidation, wherein the molding face has a structure formed at least partially by the hollow chambers which have diameters in a nanometer range.
Mold according to claim I 1, wherein the structural width of the molding face is essentially 30 to 600 nm.
Mold according to claim I 1, wherein the hollow chambers have opening areas with an average diameter of 10 to 500 nm.
