The invention relates to a metal middle frame processing method which comprises the following steps of providing a metal sectional material; carrying out initial processing on the front surface and the reverse surface of the metal sectional material, processing a front-side initial groove in the middle of the front surface of the metal sectional material, processing a reverse-side initial groove in the middle of the reverse surface of the metal sectional material, and obtaining a middle frame prototype; grinding double surfaces of the middle frame prototype; processing an injection molding slot position and an antenna slot position in the middle frame prototype; injection molding the middle frame prototype to obtain a composite frame; and finish-machining the composite frame so as to obtain the metal middle frame. Through carrying out initial processing on the front surface and the reverse surface of the metal sectional material before grinding the middle frame prototype and processingthe slot positions, stresses on the middle frame prototype through the front-side initial groove and the reverse-side initial groove are released, so that the generation of local deformation and theinfluence on a flatness effect caused by the action of an internal stress during the follow-up processing of the composite frame can be avoided. The invention further comprises the metal middle framemanufactured by using the processing metal middle frame processing method.
Description
technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a method for processing a metal middle frame and the metal middle frame. Background technique [0002] With the continuous development of mobile terminal technology, the application of smart phones, handheld computers and other electronic devices has become very common and has become an important part of people's work and life. The shell of electronic devices usually adopts a metal middle frame structure, which has The advantages of wear resistance and easy heat dissipation can make the product leave a high-end impression on users. [0003] In the production and assembly of these electronic devices, the metal middle frame is first processed by CNC machine tools, and then the metal middle frame in the installation of circuit boards, batteries, etc. is assembled, and the capacitive touch screen and battery cover are installed on the front and back of the metal middle f...
