Abstract
La présente invention concerne un procédé de fabrication d'un panneau de garnissage pour véhicule en mousse d'uréthane selon lequel on utilise une contre-pression ou une pression positive pour éliminer les poches d'air inhérentes au moulage des mousses d'uréthane. Au cours du moulage du panneau de garnissage, on applique une pression positive sur la couche extérieure qui forme la surface extérieure ou visible du panneau de garnissage pour contrecarrer la migration des bulles d'air vers la surface supérieure de la mousse d'uréthane qui forme le noyau du panneau de garnissage.
