The invention relates to a method for producing a profile segment of a segmented casting-vulcanizing mould for vehicle tyres, the moulding area of which moulds a segment of the tread profile of a tyre to be vulcanized, comprising the following steps: - creating a rigid model segment, which has a casing-like tread surface - milling the profile positive of the tread into the casing-like tread surface of the model segment to obtain the master model - creating a flexible impression from the master model, preferably in silicone rubber, - creating a rigid plaster cast from the impression, preferably in silicone rubber, to form a casting core segment - casting all of the annular, placed-together casting core segments with an aluminium-magnesium alloy to obtain a vulcanizing mould, which is subsequently in turn divided into individual profile segments. A plasma coating is applied to the tread of the model segment, into which the profile positive of the tread is subsequently milled to obtain the master model, wherein the master model is given a defined roughness by the plasma coating. |
