Abstract

An aluminum product surface treatment method comprises the following steps that oil removing and wax removing treatment is carried out on the surface of an aluminum product; first-time leveling treatment is carried out on the aluminum product subjected to oil removing and wax removing treatment; first-time neutralizing treatment is carried out on the aluminum product subjected to first-time leveling treatment; second-time leveling treatment is carried out on the aluminum product subjected to first-time neutralizing treatment; second-time neutralizing treatment is carried out on the aluminum product subjected to second-time leveling treatment; and die removing treatment is carried out on the aluminum product subjected to second-time neutralizing treatment. According to the aluminum product surface treatment method, oil removing and wax removing treatment, first-time leveling treatment, second-time leveling treatment and die removing treatment are carried out on the aluminum product, mechanical patterns and surface spots of the aluminum product can be well removed, meanwhile, the aluminum product can be brightened, and the appearance effect of the aluminum product is effectively improved.

Description

technical field [0001] The invention relates to a surface treatment technology, in particular to a surface treatment method for aluminum products. Background technique [0002] At present, most of the existing mobile phone housings are made of plastic. The plastic shell has poor wear resistance, and scratches or even discoloration will appear after a period of use. Therefore, existing mid-to-high-end mobile phones begin to use metal shells, which not only have exquisite appearance, but also have the advantages of fine touch, wear resistance, drop resistance, and corrosion resistance, so they are very popular among consumers. [0003] In the production process of the mobile phone shell, CNC is required to process aluminum products. During the processing of aluminum products, rough tool lines are produced due to tool wear or machine vibration, which affects the appearance of aluminum products. Contents of the invention [0004] Based on this, it is necessary to address the...
