Title (EN) PROCESS FOR MANUFACTURING, BY INJECTION, A PLASTIC PART COMPRISING A TECHNICAL FACE AND INCORPORATING A REINFORCING ELEMENT
(FR) PROCÉDÉ DE FABRICATION PAR INJECTION D'UNE PIÈCE EN MATIÈRE PLASTIQUE COMPORTANT UNE FACE TECHNIQUE ET INCORPORANT UN ÉLÉMENT DE RENFORT
Abstract:
(EN) This process for manufacturing a plastic part (1) having a first technical face and a second face, in a mold comprising a first shell intended to form the first face endowed with impressions intended to form technical members of the technical face and a second shell intended to form the second face, the first shell and the second shell delimiting a cavity that forms the part (1), comprises the following steps: - providing a porous reinforcing element (3); - draping the reinforcing element (3) over the first shell by covering the surface of the first shell and the impressions intended to form the technical members; - retaining the reinforcing element (3) on the first shell by retaining means; - bringing the first shell and the second shell together; - injecting a plastic in order to fill the cavity, the plastic passing through the porous reinforcing element (3) in order to fill impressions intended to form the technical members; - moving the first and second shells apart; - ejecting the plastic part (1).
(FR) Ce procédé de fabrication d'une pièce en matière plastique (1) ayant une première face technique et seconde face, dans un outillage comprenant une première coquille destinée à former la première face dotée d'empreintes destinées à former des organes techniques de la face technique et une seconde coquille destinée à former la seconde face, la première coquille et la seconde coquille délimitant une cavité formant la pièce(1), comprend les étapes suivantes: - Fournir un élément de renfort (3) poreux; - Draper l'élément de renfort (3) sur la première coquille en recouvrant la surface de la première coquille et les empreintes destinées à former les organes techniques; - Retenir l'élément de renfort (3) sur la première coquille par des moyens de retenue; - Rapprocher la première coquille et la seconde coquille; - Injecter une matière plastique pour remplir la cavité, la matière plastique traversant l'élément de renfort poreux (3) pour remplir des empreintes destinées à former les organes techniques; - Ecarter les première et seconde coquilles; - Ejecter la pièce plastique (1).
