Machining method for shell and shell

Abstract

The invention provides a machining method for a shell and the shell. The machining method for the shell comprises the steps that ink is sprayed to the surface of a metal blank material, and the ink iscured; preset gas is used for carrying out laser etching on the end face of the side, close to the ink, of the metal blank material with the cured ink through preset wave lengths and preset power; primary anodic oxidation treatment is carried out on the metal blank material which is subjected to laser etching; a solvent is used for removing the ink of the metal blank material which is subjected to primary anodic oxidation treatment; and secondary anodic oxidation treatment is carried out on the metal blank material with removed ink to form the shell. According to the machining method, machining of ink spraying, lather etching, primary anodic oxidation treatment, ink removing and secondary anodic oxidation treatment are sequentially carried out on the metal blank material, the shell in different colors or the shell in the same color but in different textures is formed, the preset gas is used for carrying out laser etching on the surplus ink on the metal blank material, and that is thegas is used for carrying out multi-direction, multi-angle and multi-dimension laser etching on the ink cured metal blank material.

Description

technical field [0001] The invention relates to the technical field of mobile phone processing, in particular to a processing method for a casing and the casing. Background technique [0002] In the related art, when anodizing the surface of the metal shell of the mobile phone, the excess ink on the surface of the metal shell is usually removed by exposing and developing the film sheet after ink jetting, but this processing method is limited by the film The shape of the sheet (the film sheet is a sheet-like PET (polyethylence terephthalate, polyethylene terephthalate) sheet), so this method cannot be used to manufacture 3D products, which reduces the market competitiveness of the product. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] For this reason, the first aspect of the present invention proposes a processing method for the casing. [0005] A second aspe...
