Embodiment Construction
[0035] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0036] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

The invention relates to a middle frame manufacturing method. The method comprises the steps that a metal middle plate is provided; a plastic frame is formed on the outer periphery of the middle platein an injection molding mode, and blind holes are formed in the positions of preset side holes in the frame; the outer surface of the frame is subjected to paint spraying treatment and electroplatingtreatment; and the blind holes are machined into through holes through CNC machining to obtain the preset side holes, and a milling cutter avoids an opening part of each blind hole in the CNC machining process. Meanwhile, the invention provides a middle frame and electronic equipment. The beneficial effects of the invention are as follows: in the middle frame manufacturing process, a frame made of plastic is formed on the periphery of a metal middle plate in an injection molding mode. The frame is endowed with metallic luster through paint spraying treatment and electroplating treatment, theproblem of forming of side holes in the frame is solved in the mode that blind holes are firstly formed through injection molding and then CNC punching is conducted, it is guaranteed that the appearance of the frame is good, and therefore the purposes of reducing the machining difficulty and improving the working efficiency are achieved.
Description
technical field [0001] The invention relates to the technical field of electronic product manufacturing, in particular to a manufacturing method of a middle frame, a middle frame, and an electronic device. Background technique [0002] Most mobile terminals use a combination of a front cover, a middle frame, and a rear cover to form a basic frame structure of the product. The front cover is mainly used to install the display screen, and in some designs, a full-screen design is also adopted, that is, the display screen replaces the traditional front cover. The middle frame is the carrier of most of the electronic devices of the mobile terminal, and is the core part of the mobile terminal. The back cover covers the side of the middle frame that is opposite to the display screen, and is used to protect the electronic devices on the middle frame. [0003] Most of the traditional middle frames are all-metal products, and their overall weight is relatively large. In the process ...
