The invention relates to a method for manufacturing a molding element (1) for a tire mold. The molding element (1) comprises a fritted portion (11) and an unfritted portion (13) that is secured to the fritted portion (11). The fritted portion (11) includes a shell (15) and a core that is located inside the shell (15) and is integral with said shell (15). The core comprises a meshed structure including a plurality of cavities (21). The manufacturing method includes a step of manufacturing the fritted portion (11) of the molding element (1) from a metal powder that is deposited on a planar surface of a mounting plate (13) and is amalgamated layer by layer, wherein the fritted portion (11) is secured to the mounting plate (13) by the amalgamated metal powder. The method also comprises a step of machining the mounting plate (13) so as to form the unfritted portion (13) of the molding element (1).
