Abstract

L'invention concerne un procédé de réalisation d'un écran (1) comprenant les étapes suivantes : prévoir une coque (2) à base de matériau déformable par compression ; prévoir un moule de moulage par injection-réaction, ledit moule comprenant une matrice (3) et un couvercle (4) définissant un plan de joint (5) se prolongeant vers l'intérieur dudit moule par un espace (6) de réception d'une bande périphérique (7) de ladite coque ; disposer ladite coque contre ladite matrice ; injecter un mélange précurseur de mousse (10) de polyuréthanne élastiquement compressible sur la face d'envers (11) de ladite coque de manière à surmouler ladite coque par la mousse, ledit moule étant pourvu d'une lame d'étanchéité (12) rigide issue du couvercle et positionnée en regard dudit espace de manière à former une saillie dedans quand ledit moule est fermé pour réaliser une compression localisée de ladite bande permettant d'éviter les fuites périphériques de mousse.
