Abstract
A metal shell of an electronic device and a method for fabricating the metal shell are provided. The method for fabricating the metal shell includes: stamping out a side wall and a bottom portion of the metal shell from a metal sheet, wherein the stamping retains a reserved material at a first position on the side wall; bending and shoving the reserved material on the side wall towards an inner side of the side wall, until a protruding portion is formed at the inner side of the side wall; removing an excessive portion of the protruding portion to shape the protruding portion into a plastic gripping structure of a preset shape; and injecting and filling the plastic gripping structure with plastic.
