Abstract
A method for manufacturing an aluminium mould () segment () for curing and vulcanizing a tyre comprises: a) fixing at least one thin blade () for the formation of the grooves in the tire tread, in a mould form made of friable material, so that an exterior part of the thin blade is embedded in the material of the mould form and so that an interior part projects from this mould form, this thin blade being made from maraging steel and having been obtained by a selective laser melting method, b) closing the mould form and pouring or injecting aluminium into it, coating the interior part of the thin blade, c) breaking away the mould form to obtain the mould segment. The thin blade () is subjected to a peening treatment with a material with a Vickers hardness between 340 and 500 HV and with dimensions smaller than 0.3 mm.
