Embodiment Construction

[0021] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used in the drawings and description to refer to the same or like parts.

[0022] Figure 1 to Figure 5 A schematic cross-sectional view of the manufacturing process of the casing according to an embodiment of the present invention. First, please refer to figure 1 , a magnesium alloy substrate 10 is provided. The magnesium alloy substrate 10 can be formed by semi-solid injection molding (Thixomolding) or diecasting (diecasting), and the outer surface 11 of the magnesium alloy substrate 10 is substantially a flat surface. Next, please refer to figure 2 The protection film 20 is formed on the outer surface 11 of the magnesium alloy substrate 10 by means of micro-arc oxidation treatment or chemical conversion treatment, so as to prevent the magnesium alloy subst...

Abstract

The invention provides a manufacturing method of a casing. The manufacturing method comprises the following steps that first, a magnesium alloy base material is provided; then, a protective film is formed on the magnesium alloy substrate; then, grinding, cutting or engraving is performed to remove the local protective film and the local magnesium alloy substrate; and then, electrophoretic coating treatment is performed to form a light-transmitting coating covering the protective film and the magnesium alloy substrate. The invention further provides a casing.

Description

technical field [0001] The invention relates to a casing, in particular to a casing and a manufacturing method thereof. Background technique [0002] Because magnesium alloy not only has the characteristics of light weight, good strength, good heat dissipation and excellent electromagnetic shielding ability, but also meets the development trend of thinner and lighter electronic products, it has been widely used to make casings. In order to prevent corrosion, in the process of making the magnesium alloy casing, the surface of the magnesium alloy casing must be subjected to micro-arc oxidation treatment (Micro-Arc Oxidation) or chemical conversion treatment (conversion coating treatment), so that the surface of the magnesium alloy casing Forms a protective film. After that, paint coating is carried out. Since the surface of the magnesium alloy casing is covered by multiple film layers, it is difficult to maintain the metallic texture of the magnesium alloy casing. Contents...
