Manufacturing method of metal mobile phone case and mobile phone case manufactured by the method

Abstract

The invention relates to the technical field of mobile phone manufacture, in particular to a manufacturing method for a metal mobile phone outer shell and the mobile phone outer shell manufactured by adoption of the manufacturing method. Technically, the mobile phone outer shell is divided into an outer shell workblank, an upper part and a lower part, the manufacturing method comprises the following steps that the outer shell workblank is extruded by adopting an extrusion molding technology firstly, then the outer shell workblank is machined through wire-electrode cutting, then the outer shell workblank is bent, a structure which can be matched with the upper part and the lower part is machined through CNC, and finally, the structure and the upper part and the lower part which are machined by adopting the CNC are assembled. According to the manufacturing method, the weaknesses of a traditional CNC full machining way are solved, and the purposes of being low in cost, short in time consuming and high in yield rate are achieved; on the textures, 7-series aluminum is used, through the using of the 7-series aluminum, the shortages of being soft in texture, easy to deform of 6-series aluminum adopted commonly in the prior art are overcome, the demands of markets can be met, and bending and deformation of the mobile phone shell caused by external force do not need to be worried.

Description

[technical field] [0001] The invention relates to the technical field of mobile phone manufacturing, in particular to a method for manufacturing a metal mobile phone case and a mobile phone case manufactured by the method. [Background technique] [0002] At present, many materials are used in mobile phone manufacturing, such as aluminum and stainless steel, among which aluminum is the most widely used. There are many kinds of aluminum materials, and now 5 series aluminum and 6 series aluminum are widely used. But referring to Table 1, there are many deficiencies in 5-series aluminum and 6-series aluminum, so the present invention uses 7-series aluminum to process and manufacture mobile phone shells. However, due to the fact that most of the existing processes are integrally formed, the cost is high, and the hardness of the 7-series aluminum is super hard, it is difficult to process the 7-series aluminum with the existing methods. Therefore, it is necessary to develop a new...

Problems solved by technology

[0005] The purpose of the present invention is to solve the deficiencies of the prior art, to provide a method for manufacturing a metal mobile phone shell and the mobile phone shell manufactured by the method. Aluminum and 6-series aluminum are easy to cause the bending phenomenon of mobile phones, and the mobile phone shell is divided into shell blanks and upper and lower accessories, and the shell blanks are made by extrusion molding technology, and the upper and lower accessories are processed by CNC technology, which solves the problems of the prior art. High cost problem, greatly reduces processing time and cost
