Manufacturing method of metal mobile phone shell

The invention provides a manufacturing method of a metal mobile phone shell. The method comprises the following steps: performing near-molding processing on a front surface of a blank: performing CNC near-molding processing on a bottom wall of the front surface of the blank, wherein the allowance of the thickness of the bottom wall of the front surface of the blank is reserved on the basis of the set thickness of the bottom wall of the front surface of a mobile phone product; performing near-molding processing on a rear surface of the blank: performing CNC near-forming processing on the bottom wall of the rear surface of the blank, wherein the thickness of the bottom wall of the rear surface of the blank is the set size of the bottom wall of the rear surface of the mobile phone product; performing net-molding processing on the front surface of the blank: performing CNC net-molding processing on the bottom wall of the front surface of the blank; and removing the thickness allowance so as to enable the thicknes
