Title (EN) PROCESS FOR PRODUCING LONGER FIBERS IN INJECTION MOLDED SOLID PARTS BY DISSOLVING OF GAS DURING PLASTICIZING
(FR) PROCÉDÉ DE PRODUCTION DE FIBRES PLUS LONGUES DANS DES PIÈCES PLEINES MOULÉES PAR INJECTION PAR DISSOLUTION DE GAZ PENDANT LA PLASTIFICATION
Abstract:
(EN) The disclosure is directed to a solid part, and a device and process of making the solid part. The process includes introducing a glass fiber filled polymeric material to a hopper of an injection molding machine, where the glass fibers have a pre-molding length, melting the glass fiber filled polymeric material to form a melt in a plasticizing unit, pressurizing the plasticizing unit of the injection molding machine with a blowing agent, dissolving the blowing agent into the melt, injecting the melt into a mold cavity up to 100% of volume, and forming the solid part.
(FR) La présente invention concerne une pièce pleine, et un dispositif et un procédé de fabrication de la pièce pleine. Le procédé consiste à introduire un matériau polymère chargé de fibres de verre dans une trémie d'une machine de moulage par injection, les fibres de verre ayant une longueur avant moulage, à faire fondre le matériau polymère chargé de fibres de verre pour former une matière fondue dans une unité de plastification, à mettre sous pression l'unité de plastification de la machine de moulage par injection avec un agent d'expansion, à dissoudre l'agent d'expansion dans la matière fondue, à injecter la matière fondue dans une cavité de moule jusqu'à 100 % du volume, et à former la pièce pleine.
