Abstract

A processing method of an appearance at least includes the following steps. A metal substrate is produced through an injection molding process. The metal substrate includes magnesium and aluminum alloys. A pickling process is performed on the metal substrate to form a semi-finished metal substrate. A micro-arc oxidation (MAO) process is performed on a surface of the semi-finished metal substrate to form an appearance surface.
