Embodiment 1

[0045] Fabrication of aluminum alloy shell with flash point effect

[0046] 1. First, pre-treat the surface of the aluminum alloy material.

[0047] The aluminum alloy material is decontaminated and degreased in the cleaning tank, and then alkali-etched in the alkali tank, and then enters the neutralization tank after being washed with water, and then washed with water after neutralization.

[0048] 2. The surface of the aluminum alloy material is polished to improve the metal texture of the post-treatment.

[0049] 3. Perform metal surface treatment such as sandblasting or wire drawing on the aluminum alloy material after surface polishing.

[0050] 4. Use a laser engraving machine to engrave bright spots of 0.02mm-1mm on the sandblasted or wire-drawn aluminum alloy material.

[0051] 5. Perform anodic oxidation treatment on the aluminum alloy material after laser engraving treatment in an anodic oxidation bath.

[0052] 6. Put the anodized aluminum alloy material into the...

Abstract

The invention relates to a metal or alloy shell and a manufacturing method thereof. By means of the manufacturing method, a laser etching method is used for forming a plurality of bright points in preset positions of the surface of a metal or alloy shell material through laser etching, and then the metal or alloy shell material is subjected to coloration treatment after the laser etching treatment, so that the metal or alloy shell is obtained. The metal or alloy shell manufactured through the manufacturing method has a flashing point effect, fashionability of a product can be enhanced, and user experience is improved. According to the manufacturing method, the bright points are formed on the surface of the metal or alloy shell material in a laser etching mode, material defects, such as inherent lines of metal or ally, of a metal surface can be covered, and therefore the appearance quality of the product can be further improved.

Description

technical field [0001] The invention relates to the field of casings of electronic products, in particular to a metal or alloy casing and a manufacturing method thereof. Background technique [0002] As electronic products, especially handheld electronic terminals, are more and more widely used, users have higher and higher requirements for housings of electronic products. Novel, fashionable and cool electronic product casings have become the common choice of many consumers. However, in the manufacturing process of traditional electronic product casings, it is difficult to cover the material defects of the metal surface itself, especially some casings with strong fashion elements, thus affecting the appearance of the casing. Contents of the invention [0003] Based on this, it is necessary to provide a metal or alloy shell capable of covering material defects of the metal itself and a manufacturing method thereof. [0004] A method for manufacturing a metal or alloy shel...
