A method is for producing a profile segment of a segmented casting-vulcanizing mold for vehicle tires, the molding area of which molds a segment of the tread profile of a tire to be vulcanized, including the steps: creating a rigid model segment having 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; creating a rigid plaster cast from the impression 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 mold, subsequently divided into 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. Plasma coating gives the master model a defined roughness.
