Metal rear cover of mobile electronic product and manufacturing technology thereof

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.

AI Technical Summary

Problems solved by technology

[0003] The shells of traditional mobile electronic products are mostly made of plastic. Although plastic mobile electronic product shells are low in cost and light in weight, they have low hardness and are easily broken by impact

[0004] Moreover, most of the metal shells of existing mobile electronic products are processed by CNC, which has high processing costs and poor mass production.
