Abstract: The invention relates to a method for processing a structured surface of an embossing tool, in which the entire surface is provided with a first metallic coating and said surface having, in selected regions, at least one additional metallic coating that has a differing degree of lustre. To improve the optical properties of the material boards produced using the embossing tools, particularly if reproducing a wood texture, the invention suggests that additional differing degrees of lustre should be produced in multiple selected regions on the first coating, and be produced by a combination of metallic coatings and mechanical or chemical after-treatments. Therefore, for example, a wood pore with a defined structure can be substantially better reproduced, and the optical and haptic properties of the wood composite board produced using the press plates can thus be improved.

Abstract: A method for producing a surface structure for a metallic press plate, endless belt or a cylindrical embossing roller through at least one laser and a device for using the method. In order to provide a cost effective production for the surface structure while using environmentally friendly techniques, it is proposed to use a laser which produces the entire surface structure through partial removal of a surface of a metallic press plate, endless belt or embossing roller to be processed. Thus, the laser is controlled by a provided 3D topography, wherein control of the laser is performed through obtained x, y and z coordinates in order to produce a depth structure, so that high portions and low portions are formed.

Abstract: A method for producing a hydrophobic or superhydrophobic surface topography on a smooth or structured surface of a pressing tool in the form of a pressing plate, endless belt, or embossing roller for producing material plates, plastic films, separating films, PVC surfaces, and LVTs (luxury vinyl tiles), includes the following steps: preparing a surface template having a microstructure, making an impression of the surface using a resin, scanning the molded surface using a 3-D microscope, converting the digitalized data from the scanning process with depth measurement into grayscale bitmaps, using the grayscale bitmaps to control the machining process of an abrasive surface treatment or to apply a mask for chemically processing the pressing tool in order to produce the surface topography. For this purpose, either the pressing tool is partially covered with a mask and subjected to an etching operation or the determined grayscale bitmap data are used to control an abrasive machining head.

Abstract: The invention relates to a method for producing a surface structure on a pressing tool, in particular a pressing plate (1), endless belt or embossing roller. According to the invention, in order to avoid a lengthy etching process, the surface structure is produced by means of metal layers lying one over the other. For this purpose, at least a one-time application of a mask is performed in order to cover partial regions and at least a one-time application of a metal layer to the non-covered regions (5, 6) is performed in order to construct a surface structure composed of elevations. The two individual method steps are repeated until the desired structure depth has been reached. By means of a final treatment method, the surface can be rounded or provided with a hard chromium layer (7), for example.

Abstract: The invention relates to a method for processing a structured surface of an embossing tool, in which the entire surface is provided with a first metallic coating (6) and said surface having, in selected regions (7, 8, 9, 10, 11), at least one additional metallic coating that has a differing degree of lustre. To improve the optical properties of the material boards produced using the embossing tools, particularly if reproducing a wood texture, the invention suggests that additional differing degrees of lustre should be produced in multiple selected regions (7, 8, 9, 10, 11) on the first coating (6), and be produced by a combination of metallic coatings and mechanical or chemical after-treatments. Therefore, for example, a wood pore with a defined structure can be substantially better reproduced, and the optical and haptic properties of the wood composite board produced using the press plates can thus be improved.
