Abstract

The present disclosure relates to a method of manufacturing a metal shell and a metal case and an electronic device. Said method comprising: punching a sheet metal sheet into a side wall of a metal shell, said reservation position being retained above said side wall; placing said reservation material from said side wall above said side wall And a plurality of protrusions are formed on the inner side of the side wall; and the remaining material on the protruding portion is removed in accordance with a predetermined shape of the gripping structure to form the gripping structure And injecting the gripping structure to fill the gripping structure with plastic. The technical solution of the present invention can avoid the press molding of the metal sheet by CNC, reduce the difficulty of forming the metal material, save the time of processing the metal shell, and improve the production efficiency of the metal shell.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to a method for manufacturing a metal casing, the metal casing, and electronic equipment. Background technique [0002] In order to satisfy the user's tactile and visual experience, more and more smartphones use metal shells. In related technologies, the unibody process is more about punching and forging a whole piece of metal material out of the basic shape of the metal shell, and then using a large number of computerized numerical control machine tools (Computerized Numerical Control Machine, referred to as CNC) to process The actual shape of the metal shell is stamped and forged. Since the metal shell needs to be fixed by the gripping structure after stamping, the thickness of the gripping structure determines the thickness of the required metal material, that is, the thickness of the metal material must be Only when the thickness of the gripping structure is greate...
