Abstract

A process for manufacturing a timepiece component having a first step (E) consisting in arranging a metal insert in an injection mold, one surface of said metal insert being at least partially coated with a primer, a second step (E) of injecting an elastomer material into the injection mold in order to overmold the elastomer material over the metal insert, a third step (E) of vulcanizing the elastomer material, wherein the temperature of the injection mold is variable, and a step (E) of increasing the temperature of the injection mold between a first temperature at a first instant during the injection second step (E), and a second temperature higher than the first temperature at a second instant, during the vulcanization third step (E).
