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 degreasing in the cleaning tank, and then alkali-etched in the alkali tank. After one wash, it enters the neutralization tank, and then washes after neutralization.

[0048] 2. Surface polishing is performed on the surface of the aluminum alloy material to improve the metallic texture of the post-processing.

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

[0050] 4. Using a laser laser engraving machine, laser engraving 0.02mm-1mm bright spots on the sandblasted or brushed aluminum alloy material.

[0051] 5. Anodize the aluminum alloy material after laser engraving treatment in an anodizing bath.

[0052] 6. Put the anodized aluminum alloy material into the coloring tank for dyeing, and th...

[0054] Fabrication of stainless steel shell with flash point effect

[0055] 1. First, pre-treat the surface of the stainless steel material.

[0056] Decontamination and degreasing of stainless steel materials are carried out in the cleaning tank.

[0057] 2. Surface polishing is performed on the surface of the stainless steel material to improve the metallic texture of the post-processing.

[0058]3. Sandblast the stainless steel material after surface polishing.

[0059] 4. Using a laser laser engraving machine, laser engraving 0.02mm-1mm bright spots on the sandblasted stainless steel material.

[0060] 5. After cleaning, PVD coloring treatment is performed on the laser engraved stainless steel material.

[0061] 6. According to the demand, the anti-fingerprint coating is plated on the stainless steel material after coloring.

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 electronic product casings, in particular to a metal or alloy casing and a manufacturing method thereof. Background technique [0002] As electronic products, especially handheld electronic terminals, become more and more widely used, users have higher and higher requirements for electronic product housings. Novel, fashionable and cool electronic product casings have become a common choice for many consumers. However, in the production process of traditional electronic product casings, it is difficult to cover up the material defects of the metal surface itself, especially some casings with strong fashion elements, thus affecting the appearance of the casings. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a metal or alloy casing that can cover up the material defects of the metal itself and a manufacturing method thereof. [0004] A method for making a metal or alloy shell, compris...
