Abstract

A shell, an electronic device, and a shell manufacturing method. The shell manufacturing method comprises: provide a first shell base (10), which comprises a first surface (11) and a second surface (12) provided opposite each other; provide a forging and pressing mold (30), which comprises a first forging mold (31) and a second forging mold (32) performing pressing with respect to the first forging mold (31); the first forging mold (31) and the second forging mold (32) respectively press against the first surface (11) and the second surface (12); obtain a second shell base (40), which comprises a first curved surface (41), a second curved surface (42) provided opposite the first curved surface (41), and a flash edge (42) located between the first curved surface (41) and the second curved surface (42); and remove the flash edge (43). According to the manufacturing method, the processing time is shortened and the production costs for shells are reduced.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a method for manufacturing a casing. Background technique [0002] At present, in the production process of mobile phone casings, most of them use milling technology to mill the appearance surface of the casing. However, since there are multiple curved surfaces on the exterior surface of the shell, it takes a long time to mill the shell, which increases the production cost of the shell. Contents of the invention [0003] The invention provides a method for manufacturing a shell that reduces production costs. [0004] The present invention provides a shell manufacturing method, wherein the shell manufacturing method includes: [0005] providing a first housing base having oppositely disposed first and second surfaces; [0006] A forging die is provided, the forging die has a first forging die and a second forging die extruded relative to the first forging die; [0007] th...
