Title (EN) METHOD FOR MANUFACTURING METAL FRAME FOR MOBILE TERMINAL
(FR) PROCÉDÉ DE FABRICATION D’UN CADRE MÉTALLIQUE POUR TERMINAL MOBILE
(KO) 휴대용 단말기의 메탈프레임 제조방법
Abstract:
(EN) The present invention relates to a method for manufacturing a metal frame of a mobile terminal, comprising: a metal body forming step of multistage pressing, in a continuous and stepwise manner, a metal material to integrally form a metal body including a rear plate constituting the entire outside rear of the mobile terminal and a hollow bezel sidewall protruding from one side of the rear plate; and a resin injection molding step of injection-molding a resin injection part into the metal body by insert injection molding using the metal body as an insert, wherein the metal body forming step forms a flange protruding outward along the periphery of the bezel sidewall during the multistage press forming, forms a segment hole in the bezel sidewall at a position where an antenna of the mobile terminal is installed, and forms a connection part connected to the rear plate on the bezel sidewall in which the segment hole is formed and separated, and wherein the resin injection molding step comprises: a flange cutting step for cutting the flange out of the bezel sidewall, in which the resin injection part is injection-molded, so as to close the segment hole and expose the connection part, wherein the flange cutting step is performed after the resin injection molding step; an anodizing step of applying an anodic oxidation treatment to the surface of the metal body and depositing an organic dye on the surface of the metal body to realize a color; and a connection part cutting step, performed after the anodizing step, of cutting and removing the connection part exposed from the resin injection part.
(FR) La présente invention concerne un procédé de fabrication d’un cadre métallique pour un terminal mobile, comprenant : une étape de formation de corps métallique comportant plusieurs phases de pression, d’une manière continue et pas à pas, d’un matériau métallique pour former d'un seul tenant un corps métallique incluant une plaque arrière constituant toute la face arrière externe du terminal mobile et une paroi latérale inclinée creuse faisant saillie d’un côté de la plaque arrière ; une étape de moulage par injection de résine consistant à mouler par injection une partie de résine injectée dans le corps métallique par un moulage par injection d’insert en utilisant le corps métallique en tant qu’insert, l’étape de formation de corps métallique formant un flasque faisant saillie vers l’extérieur le long de la périphérie de la paroi latérale inclinée pendant la formation à plusieurs phases de pression, formant un segment creux dans la paroi latérale inclinée à une position où une antenne du terminal mobile est installée, et formant une partie de connexion connectée à la plaque arrière sur la paroi latérale inclinée dans laquelle le segment creux est formé et séparé, l’étape de moulage par injection de résine comprenant : une étape de coupe de flasque consistant à découper le flasque de la paroi latérale inclinée, où la partie de résine injectée est moulée par injection, de sorte à fermer le segment creux et à découvrir la partie de connexion, l’étape de coupe de flasque étant réalisée après l’étape de moulage par injection de résine ; une étape d’anodisation consistant à appliquer un traitement d’oxydation anodique à la surface du corps métallique et à déposer un colorant organique sur la surface du corps métallique pour réaliser une couleur ; et une étape de coupe de partie de connexion, réalisée après l’étape d’anodisation, consistant à couper et à supprimer la partie de connexion découverte sur la partie de résine injectée.
