Shell manufacturing method, shell and mobile terminal

Abstract

The invention provides a shell manufacturing method, a shell and a mobile terminal. The shell manufacturing method comprises the following steps that a first shell matrix is provided, wherein the first shell matrix is provided with a first surface and a second surface which are oppositely arranged; the first surface and the second surface of the first shell matrix is forged and pressed; a second shell matrix is obtained, wherein the second shell matrix is provided with a first allowance part, a second allowance part which is arranged opposite to the first allowance part, and a molding flash located between the first allowance part and the second allowance part, the allowance size of the first allowance part is smaller than the allowance size of the second allowance part, a third allowancepart is further connected between the first allowance part and the molding flash, and the allowance size of the third allowance part is larger than the allowance size of the first allowance part; andthe molding flash is removed. Therefore, the third allowance part can meet the allowance requirement of a complex structure, and the forming quality of the shell manufacturing method is improved.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a method for manufacturing a shell, the shell and a mobile terminal. Background technique [0002] At present, in the production process of mobile phone casings, most of them are processed by forging process, and a processing allowance is reserved to facilitate subsequent further processing. However, in the forging process, the reserved machining allowance is relatively uniform, which cannot meet the complex structure of the shell with local changes. In the process of removing the machining allowance, in the face of the complex structure with local changes, the reserved machining allowance cannot guarantee the subsequent processing, and there is a shortage of materials, which makes the molding quality of the shell manufacturing method not high Contents of the invention [0003] The invention provides a method for manufacturing a housing with improved molding quality, the ho...
