METALLIC CASE FOR ELECTRONIC PROUDCT MANUFACTURED BY USING RUBBER BULGING

摘要

The present invention relates to a metal case for an electronic product that is produced using a rubber bulging process, the rubber punch the steps of bulging a metallic plate by a press-molding face of the square shape by using a reverse gradient; A step of processing the bulging NC machining or pressing a metal sheet; The NC machining or stamping the metal blanking plate again and then drawing process and trimming; Back pressure forming a metal sheet by punching the trim is characterized in that a rubber prepared by the process comprising the step of including the conglomerate ranging. According to the present invention, by manufacturing a metal case for an electronic product using the rubber bulging liquid pressure bulging processing and conventional NC machining, hydro-forming molding process with low production cost than the metal case for an electronic product with a high production efficiency can be produced in large quantities. ;
