Example Embodiment

[0038] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0039] The invention provides a manufacturing process for a metal back cover of a mobile electronic product, such as Figure 5a-5e As shown, including the following steps:

[0040] (a) The strip 300 is etched first and then cut to the required length;

[0041] (b). Press and shape the cut strip 300 into a back cover 101, an upper frame 102, and a lower frame 103, and then perform CNC rough machining on the back cover 101, upper frame 102, and lower frame 103;

[0042] (c) The rear cover 101 is overlapped with the upper frame 102 and the lower frame 103 to form the rear cover shell 100;

[0043] (d) The metal back cover of the mobile electronic product is formed through the secondary fixing of injection molding, and the back cover inner plate 200 is formed through injection molding;

[0044] (e) Machining the metal back cover of the mobil...

Abstract

The invention relates to the technical field of mobile electronic product shell manufacturing, in particular to a manufacturing technology of a metal rear cover of a mobile electronic product. The manufacturing technology comprises the following steps that a material strip is etched and then is cut to be in the needed length; punching and forming are conducted on the cut material strip to form a rear cover plate, an upper border and a lower border, and then CNC rough machining is conducted on the rear cover plate, the upper border and the lower border; the metal rear cover of the mobile electronic product is formed through injection molding secondary fixation, and a rear cover inner plate is formed through injection molding; the metal rear cover, processed through injection molding, of the mobile electronic product is machined; post-processing is conducted on the metal rear cover of the mobile electronic product. According to the manufacturing technology of the metal rear cover of the mobile electronic product, the number of working procedures of machining can be reduced, or the duration of machining can be shortened, and the appearance of the rear cover of the mobile electronic product can be more attractive. Meanwhile, the invention provides the metal rear cover of the mobile electronic product. The hardness of the metal rear cover of the mobile electronic product is enhanced, and the metal rear cover of the mobile electronic product cannot be easily broken, and is light in weight.

Description

technical field [0001] The invention relates to the technical field of manufacturing shells of mobile electronic products, in particular to a manufacturing process for a metal back cover of a mobile electronic product and the metal back cover of a mobile electronic product manufactured by the process. Background technique [0002] With the development of mobile communications and the improvement of people's living standards, the use of mobile electronic products has become more and more popular. Mobile electronic products have become an indispensable communication tool in people's lives. People are increasingly demanding the functional diversity of mobile electronic products. At the same time, the requirements for the appearance of mobile electronic products are getting higher and higher. [0003] Traditional mobile electronic product casings are mostly made of plastic. Although plastic mobile electronic product casings are low in cost and light in weight, their hardness is ...
