Abstract

L'invention concerne un procédé de peinture de pièces automobiles en matière plastique, en particulier de pare-chocs de véhicules automobiles. Pour préparer l'opération de peinture, les pièces automobiles en matière plastique traversent en continu une zone de nettoyage où elles sont soumises à un processus de nettoyage au CO2 au moyen d'un dispositif de nettoyage à commande automatique et, après ce nettoyage, les pièces automobiles en matière plastique arrivent dans une zone de peinture où elles sont dotées d'au moins une couche de peinture par un processus de peinture automatique. Selon l'invention, le dispositif de nettoyage est déplacé à intervalles réguliers depuis une position de nettoyage jusque dans une position de contrôle, puis le dispositif de nettoyage charge en CO2 une éprouvette (dans la position de contrôle) dans le cadre d'un processus de contrôle et le dispositif de nettoyage est ensuite à nouveau déplacé dans une position de nettoyage. Une évaluation automatique de la charge en CO2 de l'éprouvette permet de conclure à un état de bon fonctionnement du dispositif de nettoyage de telle sorte que, globalement, le processus de contrôle ne dégrade pratiquement pas le nettoyage automatique des pièces automobiles en matière plastique traversant en continu la zone de nettoyage.
