Abstract: A process for manufacturing a molding element (10) of a curing mold, the molding element being manufactured by an additive manufacturing process, the molding element comprising a molding inner surface (12) and an outer surface (14), and the molding element comprising at least one vent (20) through which air can pass between the molding inner surface and the outer surface of the molding element, comprises the following steps: (a) additively manufacturing the molding element and at least one porous region in this molding element, the porous region being manufactured so as to have a material density lower than the material density of the molding element outside this porous region, and (b) using a process for removal of material by a laser beam or by a laser beam contained in a water jet to produce at least one vent (20) in the porous region.

Abstract: A Method for manufacturing molding elements for molds is provided herein. The molds are used for molding tires provided with a tread with a circumferential arrangement of tread pattern elements. The method includes: a step consisting in aligning a plurality of basic linings; a step consisting in generating, from the basic tread circumference portion, an intermediate support; and obtaining an unfinished molding element from the intermediate support.

Abstract: Cutting method for cutting a semi-finished molding element to yield segments of a mold for molding and vulcanizing tires is disclosed herein. The said molding element includes a plurality of segments originating from one and the same molding operation, the said molding element also includes at least one pair of male securing members on each side of a molding face to form the tread patterns in the tread of the tire that is to be molded.
