Processing method of metal middle frame mobile phone shell structure

Abstract

The invention discloses a processing method of a metal middle frame mobile phone shell structure and relates to the technical field of processing of mobile phones. The processing method comprises the following steps: A, stamping a blank of the metal middle frame by using a metal plate; B, milling an auxiliary antenna area on the blank of the metal middle frame in a CNC manner and retaining a connection position; C, forming a metal bottom shell by using an aluminum die casting manner; D, connecting the blank of the metal middle frame with the metal bottom shell to be a whole body; E, forming a main antenna area on the blank of the metal middle frame by using an injection molding manner; and F, milling off the connection position on the blank of the metal middle frame in the CNC manner to obtain the metal middle frame mobile phone shell structure. By combining processes of stamping molding, injection molding and CNC processing, the metal middle frame mobile phone shell structure is processed; the metal middle frame mobile phone shell structure is stable in process, high in production efficiency, short in processing time and low in production cost.

Description

technical field [0001] The invention relates to the technical field of mobile phone processing, in particular to a method for processing a metal middle-frame mobile phone shell structure. Background technique [0002] At present, most of the existing mobile phone housings are made of plastic. Plastic mobile phone cases have poor wear resistance, and scratches or even discoloration will appear after a period of use. In order to solve the above-mentioned problems of the above-mentioned plastic mobile phone cases, more and more metal middle-frame mobile phone cases have been extensively researched and developed. Due to their good wear resistance and exquisite appearance, metal middle-frame mobile phone cases are loved by consumers. However, the existing metal middle-frame mobile phone cases are generally processed by CNC from a whole piece of metal profile. Due to the limitation of the processing method, the CNC processing takes a long time to form, the production cost is high...

AI Technical Summary

Problems solved by technology

However, the existing metal middle-frame mobile phone cases are generally processed by CNC from a whole piece of metal profile. Due to the limitation of the processing method, the CNC processing takes a long time to form, the production cost is high, and the mass production is poor, and the CNC processing method is easy to adjust. The product is knocked and damaged, resulting in poor appearance

[0003] Based on the above, there is an urgent need for a metal middle frame mobile phone shell structure processing method to solve the problems of long processing time, high production cost and poor mass production existing in the existing metal middle frame mobile phone shell structure processing methods
