Abstract

L'invention concerne la fabrication d'une pièce de mousse portée par un support.Elle se rapporte à un procédé de fabrication qui comprend la disposition d'une couche de mousse (18) sur une surface d'une partie de moule (10), alors que le moule est ouvert, la fermeture du moule afin qu'il délimite une cavité entre la couche de mousse (18) et une autre partie de moule (14), et l'injection dans la cavité d'une matière plastique non cellulaire destinée à former le support (20). Le procédé comprend, après la fin de l'injection de la matière plastique du support (20), une étape d'écartement progressif à vitesse déterminée des deux parties de moule (10, 14), dans une direction ayant une composante dans la direction de l'épaisseur de la couche de mousse (18).Application aux garnitures intérieures d'automobiles.
