Embodiment 1

[0039] figure 2 A schematic flow chart of the scheme of the aluminum alloy shell processing method in Example 1 is shown.

[0040] The aluminum alloy shell processing method of embodiment 1 comprises:

[0041] In step S100 , the aluminum alloy material is processed to obtain the outer shell and the inner cavity structure. The shape and related internal cavity structure processing of aluminum alloy materials can be processed in sequence, such as CNC processing, surface grinding, and surface sandblasting. The non-high-gloss area has completed the processing that should be completed before anodizing.

[0042] Sand blasting is the process of cleaning the surface of the substrate by the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the spray material (such as alumina, diamond, corundum, quartz sand, etc.) to the surface of the workpiece to be treated at a high speed, so that the appearance or shape of the outer surface...

Embodiment 2

[0064] image 3 A schematic structural view of an aluminum alloy housing according to an embodiment of the present invention is shown. The aluminum alloy shell of the embodiment 2 uses the above-mentioned processing method to obtain an oxide film on the high-gloss side and an oxide film on the non-gloss area through one anodic oxidation process on the aluminum alloy substrate 300 .

[0065] Due to the oxide film on the high-gloss side (including image 3 The second undyed layer 330 and the second dyed layer 340) and the oxide film in the non-high light area (including image 3 The first undyed layer 310 and the first dyed layer 320) are obtained by anodizing at the same time, so they have the same oxide film thickness, color and film properties, and there is no white line that ordinary high-gloss same-color anodizing has, Therefore, the appearance integrity of the highlight edge and the non-highlight area is very good.

[0066] Moreover, the present invention does not need ...

Abstract

The invention discloses an aluminum alloy shell, a machining method thereof and electronic equipment. The machining method of the aluminum alloy shell comprises the steps that the shape and an inner cavity structure of an aluminum alloy material are machined, so that a shell workpiece is obtained; protective film is attached to a non-highlight machining area of the shell workpiece; a highlight machining area of the shell workpiece is machined to obtain a highlight side; and after the protective film is removed, the non-highlight machining area and the highlight machining area are subjected tonormal primary anodic oxidation machining at the same time. According to the technology provided by the invention, oxidation film of the highlight side and the oxidation film of the non-highlight areaare the same in thickness, color and film layer property, white line defects existing during ordinary highlight same color anodic oxidation do not exist, and the appearance integrity is very good.

Description

technical field [0001] The invention relates to a metal processing technology, in particular to an aluminum alloy casing, a processing method thereof, and an electronic device. Background technique [0002] Modern daily life has become more and more inseparable from electronic devices, such as tablet computers, smart phones, e-books, portable notebooks, etc. As people have higher and higher requirements for the appearance of electronic products, higher requirements are also put forward for the materials and processing technology of electronic product casings. [0003] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. Due to the low density of aluminum alloy, but relatively high strength, which is close to or exceeds that of high-quality steel, it has good plasticity and can be processed into various profiles, so it...
