METHOD FOR MICROSTRUCTURING THE FORM-GIVING SURFACE OF A FORM-GIVING TOOL FOR PRODUCING MICROSTRUCTURES IN GLASS OR SYNTHETIC MATERIAL AND FORM-GIVING TOOL APPURTENANT THERETO

摘要

The invention relates to form-giving tools which are typically used in hot form-giving methods for impressing the given structure into the substrate which is present in the plastic state and made of glass or synthetic material. The aim of the invention is to meet the great demands of corrosion resistance, capacity of resistance to wear, contact behaviour etc. To this end, the form-giving surface of the form-giving tool consists of special materials that are not easy to structure. The invention relates to a method for structuring. Said method can be carried out in a cost-effective manner. A photo lacquer layer (2) having cavities (2a) and raised locations (2b) is structured on the unstructured surface using the lithography method. Said layer is coated with the contact material, preferably by thermal spraying. In a subsequent treatment step, the coating (4) is brought to the structure height by laying bare the photo lacquer layer at the raised locations (2b). The layer is then removed.
