Abstract

La présente invention concerne un procédé de fabrication d'un boîtier en céramique de zircone pour un appareil électronique portatif, le boîtier portant un logo qui est esthétiquement amélioré de façon spectaculaire. Le logo est constitué de zircone similairement au boîtier en zircone et la composition du logo est la même que celle du boîtier en zircone à l'exception d'additifs colorants. Selon la présente invention, un procédé de frittage de boîtier en zircone, dans lequel le boîtier en zircone rétrécit, est effectué et le même procédé est effectué pour le logo, ce qui empêche de cette manière la forme du logo de se gondoler et permet d'obtenir une amélioration esthétique spectaculaire pour le logo.
