Title
(EN) METHOD FOR MANUFACTURING A MULTI-MATERIAL PRODUCT TROUGH MOULD INJECTION AND ITS MOULD
(FR) PROCÉDÉ POUR LA FABRICATION D'UN PRODUIT MULTIMATIÈRE PAR INJECTION EN MOULE ET SON MOULE
Abstract
(EN)
The present invention describes a method for manufacturing a multi-material product by injection into a mould, the injected materials, the mould itself able to perform the said method and the thus obtained plastic parts. injecting one or more first materials (3,5) into a closed mould into one or several first cavities; partially opening the mould, subsequent to first material (3,5) solidification, a simultaneous extraction occurring up to a preset value; injecting one or more second materials (9) into one or more second cavities, the said cavities allowing the second materials (9) to bind to the first materials (3,5). This method can be used for manufacturing plastic parts such as packaging or large parts for the automotive industry.
(FR)
La présente invention décrit un procédé pour la fabrication d'un produit multimatière par injection dans un moule, les matières injectées, le moule lui-même permettant la mise en œuvre dudit procédé et les pièces en matière plastique ainsi obtenues. Le procédé comprend l'injection d'une ou plusieurs premières matières (3, 5) dans un moule fermé dans une ou plusieurs premières empreintes; l'ouverture partielle du moule, après solidification des premières matières (3, 5), une extraction simultanée ayant lieu jusqu'à une valeur préréglée; l'injection d'une ou plusieurs secondes matières (9) dans une ou plusieurs secondes empreintes, lesdites empreintes permettant aux secondes matières (9) de se lier aux premières matières (3, 5). Ce procédé peut être utilisé pour la fabrication de pièces en matière plastique telles qu'un emballage ou des pièces de grande taille pour l'industrie automobile.
