Casing of electronic device

Abstract

A casing of electronic devices comprises a plastic casing, a metal coating and an oxidized layer formed on the surface of the metal coating by anodizing. The method for manufacturing the casing of electronic devices, including the following steps: (1) ejecting and forming the above plastic casing; (2) forming in metal coating on the surface of the plastic casing; (3) anodizing the plastic casing with the metal coating. In such a way, the casing of electronic devices has a metal sense and a strong erosion resistance. The method can continue the tinctorial processing after the step (3) to acquire the required color or pattern.

Description

【Technical field】

[0001] The invention relates to an electronic device casing, in particular to an electronic device casing with better appearance and surface quality. 【Background technique】

[0002] At present, in order to obtain a metal texture for the plastic case of an electronic device, a metal layer is usually deposited on the surface of the plastic case through a plastic electroplating process. Related content can refer to US Patent No. 6,045,866. However, since plastic electroplating can only be plated on less active metals, such as copper and nickel, and more active metals, such as aluminum, are difficult to plate. In addition, due to the complex process of plastic electroplating itself, the production efficiency is low and the cost is high.

[0003] To solve the above problems, US Patent No. 5,660,934 discloses a method for obtaining a metal layer on a plastic workpiece through a thermal spraying (Thermal Spraying) process. However, since the metal layer on the ...
