Abstract

The present invention relates to a method for surface structuring of workpieces, in particular molds for plastics processing, erosion electrodes or the like, in which a structured surface is applied to an unstructured workpiece surface in order to map the structure into the workpiece surface. In order to provide a method which can be carried out more quickly, and which involves no environmentally hazardous process steps, it is proposed that a structure layer which has the structured surface is arranged between an explosive layer and the workpiece surface, and the structure is forced into the workpiece surface by detonating the explosive layer or a surface-structured explosive layer is arranged on a workpiece surface, and the structure is embossed onto the workpiece by detonating the explosive layer. The invention furthermore relates to a workpiece produced using this method, such a an injection-molding mold, a blowing mold, a compression mold, a foaming mold and a pressure-casting mold, erosion electrode or the like, in which the structure is forced into the workpiece surface by means of an explosive layer.
