Abstract

The invention provides a preparation method of a middle frame. The preparation method comprises the steps of: carrying out hot extrusion on a metal pipe and a metal bar to form a composite profile, wherein the metal pipe is made of a first metal, the metal bar is made of a second metal different from the first metal, and the metal bar is located at the inner side of the metal pipe; processing the composite profile to form a middle frame blank, wherein the middle frame blank comprises an edge part and a center part located at the inner side of the edge part, the edge part is made of the first metal, and the center part is made of the second metal; and carrying out surface treatment on the surface, back to the center part, of the edge part to obtain an appearance surface so as to form the middle frame. According to the preparation method of the middle frame, the function types of the middle frame can be increased, the multi-performance requirements of the middle frame are met, and the competitiveness of products is improved. The invention further provides the middle frame and a mobile terminal comprising the middle frame.

Description

technical field [0001] The present application relates to the technical field of terminals, in particular to a middle frame, a manufacturing method thereof, and a mobile terminal. Background technique [0002] With the continuous progress of society, terminal devices such as mobile phones have become one of the indispensable products in people's life. At present, in order to ensure the exquisite appearance of the middle frame of traditional terminal equipment, the middle frame is generally processed from a single metal blank, resulting in a single function of the middle frame, and it is difficult to realize the multi-performance requirements of the middle frame at the same time. Contents of the invention [0003] The present application provides a middle frame and its preparation method, and a mobile terminal, which are used to increase the types of functions of the middle frame, realize the multi-performance requirements of the middle frame, and improve the competitivenes...
