A process for the manufacture of a glazing module comprising a pane (6) of glazing material and gaskets able to be used in automotive glazing applications in order to fill, under low pressure, a specially built mold, with a polyurethane composition having a slow reaction speed. The mold (4) is made of plastic material and has a ring type configuration, around the peripheral area of the pane (6) corresponding to the gasket's application position. The new process allows the manufacture of new window and gasket assembly at lower costs than those performed with known techniques.
Procédé de fabrication d'un module de vitrage comportant une plaque de verre (6) et des joints. Ce procédé, utilisable dans le domaine du vitrage pour automobile, permet de remplir, sous basse pression, un moule particulier avec une composition à base de polyuréthane réagissant lentement. Le moule (4) est en matière plastique et il présente une configuration de type annulaire autour de la zone périphérique de la plaque (6) correspondant à la position finale du joint. Ce nouveau procédé permet la fabrication d'un nouvel ensemble vitre/joint plus économique que ceux obtenus selon les techniques connues.
