Document Type and Number:
WIPO Patent Application WO/2012/162909
Kind Code:
A1
Abstract:
A mobile phone shell and its processing method are provided. The mobile phone shell comprises an outer shell (1) formed by metal punching, forging or injection molding, and inserts (21,22) are welded or concave structures are formed on the inner side of the outer shell. The mobile phone shell also comprises an inner shell (3) molded on the inner side of the outer shell by metal pressure casting, and the inner shell surrounds the inserts or fills into the concave structures so as to combine the outer shell with the inner shell. The processing method includes following steps: forming the outer shell by metal punching, forging or injection molding; soldering the inserts or forming the concave structures on the inner side of the outer shell; putting the outer shell into a mould and pressure casting the inner shell in the inner side of the outer shell. The method ensures the appearance requirement of the mobile phone shell, as well as reduces processing amount of cutting process, which reduces the cost of mobile phone shell largely.
