Abstract:
(DE) Verfahren zur Herstellung eines Bauteils (3) mit einer Träger-Schicht und einer Dekorations-Schicht mit einem daran angeordneten zusätzlichen Formteil (1) aus Kunststoff mit den folgenden Schritten: Einlegen einer plastifizierten Matte mit Faseranteilen als Ausgangsmaterial der Trägerschicht (12) sowie ein Zuschnitt als Ausgangsmaterial für die Dekorations­Schicht (14) in ein Pressverform-Werkzeug (20), wobei die erste Werkzeug­Hälfte (21) eine Niederdruck-Spritzeinrichtung (10) zur Herstellung eines zusätzlichen Formteils aufweist, Zusammenpressen der Werkzeug-Hälften (21, 22), um die Ausgangsmaterialien miteinander zu verbinden, und währenddessen oder anschließend Einlassen einer vorbestimmten Menge des Kunststoffs im plastischen Zustand durch einen Zuführungskanal (25) in die Kavität (23), und Bewegen des Schiebers (24) in seine Endstellung, Zurückfahren des Schiebers in seine Ausgangs-Stellung und Auseinanderfahren der Werkzeug-Hälften (21, 22), und Vorrichtung zur Durchführung des Verfahrens.
(EN) The invention relates to a method for producing a component (3) comprising a backing layer, a decorative layer and an additional moulded part (1) that is attached to said component. The method comprises the following steps: a platicised mat comprising fibre fractions, which is the starting material for the backing layer (12), is laid together with a blank, which is the starting material for the decorative layer (14), in a compression moulding tool (20), the first tool half (21) comprising a low-pressure injection unit (10) for producing an additional moulded part; the tool halves (21, 22) are pressed together to join the two starting materials; a predetermined quantity of the plastic in a fluid state is simultaneously or subsequently admitted into the cavity (23) through a supply conduit (25) and the bar (24) is displaced into its end position; return of the bar into its initial position and separation of the tool halves (21, 22). The invention also relates to a device for carrying out said method.
(FR) Procédé de fabrication d'une pièce structurale (3) pourvue d'une couche de support et d'une couche de décoration ainsi que d'une pièce moulée (1) en plastique ajoutée à ladite pièce structurale. Ledit procédé consiste à introduire un matelas plastifié comportant des proportions de fibres en tant que matière de départ de la couche de support (12) ainsi qu'une pièce découpée en tant que matière de départ pour la couche de décoration (14) dans un outil (20) de déformation par pressage, la première moitié (21) d'outil comportant une dispositif d'injection à basse pression (10) pour la fabrication d'une pièce moulée ajoutée, à serrer les moitiés (21, 22) d'outil pour lier entre elles les matières de départ, et simultanément ou ultérieurement à introduire une quantité prédéterminée de plastique à l'état souple par un canal d'introduction (25) dans la cavité (23), et à déplacer le tiroir (24) dans sa position terminale, à renvoyer le tiroir dans sa position de départ et à séparer les deux moitiés (21, 22) de moule. La présente invention concerne également un dispositif permettant de mettre en oeuvre ledit procédé.
