L'invention concerne un procédé permettant de coller un film de façon sûre. Ce film possède une température de fusion différente de la température de fusion d'un corps moulé possédant une petite surface d'adhésion et sur lequel le film peut être collé sans détériorer la forme de ce corps moulé. Ce procédé comprend les étapes consistant à placer un film plastique transparent non coloré (6) sur la surface d'extrémité à paroi fine (5) du corps moulé (1), à placer un panneau de verre (7) sur le film plastique, à presser le panneau de verre, et à faire tourner une fois la surface d'adhésion tout en dirigeant un faisceau laser (8) sur la surface d'extrémité (5). La surface d'extrémité (5) est fondue au niveau d'un point de rayonnement (9) par le faisceau laser (8) transmis à travers le panneau de verre (7) et le film plastique (6), et ce dernier est collé (6) sur la partie fondue.
