Abstract

L'invention concerne un procédé de fabrication de pièces destinées à être installées dans un véhicule, comprenant les étapes successives suivantes : enduction (1.4) d'un support sous forme liquide sur la paroi intérieure d'un moule suivie d'une étape de séchage dudit support au cours de laquelle le support se rigidifie, et enlèvement (1.10) de la pièce formée après durcissement de la mousse. De cette manière les pièces pour l'industrie automobile sont produites selon un procédé plus rapide et plus simple, tout étant de grande rigidité et présentant un bel aspect. Selon un mode particulier de réalisation, le procédé comporte une étape de projection (1.7) de mousse sur ledit support suivi d'une étape d'une première durée déterminée au cours de laquelle la mousse durcit.The invention relates to a method of manufacturing parts intended to be installed in a vehicle, comprising the following successive steps: coating (1.4) of a support in liquid form on the inner wall of a mold followed by a drying step of said support during which the support stiffens, and removal (1.10) of the part formed after hardening of the foam. In this way the parts for the automotive industry are produced in a faster and simpler process, all being of great rigidity and having a good appearance. According to a particular embodiment, the method comprises a step of spraying (1.7) foam on said support followed by a step of a first determined duration during which the foam hardens.
