Abstract

La présente invention concerne un procédé permettant de former des motifs sur la surface extérieure du boîtier tridimensionnel d'un appareil électronique par le biais d'un procédé de transfert par sublimation thermique ou d'un procédé de transfert thermique. Le procédé comprend les étapes qui consistent : à disposer d'un moule inférieur (10) qui présente une partie en saillie (11) dont la forme est similaire à la surface de fond intérieure d'un boîtier cible (99); à disposer d'un moule supérieur (20) qui comprend une unité de compression (21) et à fixer une matière élastique (30) qui adhère à la surface intérieure de l'unité de compression (21) avec une épaisseur constante de manière à appliquer une pression lors de son retrait lorsqu'elle est fixement reliée à un papier transfert (40); à placer le boîtier (99) sur la surface supérieure du moule inférieur (10) après avoir placé le papier transfert (40) sur la surface supérieure du boîtier (99) afin de fixer le papier transfert (40) jusqu'à ce que le moule supérieur (20) descende et soit fixement relié; puis à mettre sous pression le papier transfert au moyen de la matière élastique par abaissement du moule supérieur (20) et à appliquer une chaleur générée par un élément chauffant (61) d'une plaque chauffante (60) qui maintient simultanément le moule supérieur (20).
