Abstract
A manufacturing method of a casing including the following steps is provided. A magnesium alloy substrate is provided first. Next, a protective film is formed on the magnesium alloy substrate. A grinding treatment, a cutting treatment, or an engraving treatment is then performed to remove portions of the protective film and portions of the magnesium alloy substrate. An electrophoretic coating treatment is performed afterwards to form a light-transmissive coating layer covering the protective film and the magnesium alloy substrate. A casing is also provided.
Claims7
A manufacturing method of a casing, comprising:
- providing a magnesium alloy substrate having an outer surface;
- forming a protective film on the magnesium alloy substrate;
- performing a grinding treatment, a cutting treatment, or an engraving treatment to remove portions of the protective film and portions of the magnesium alloy substrate, wherein the outer surface of the magnesium alloy substrate forms a concave-convex surface having convex surfaces covered by the protective film and concave surfaces exposed to outside;
- and
- performing an electrophoretic coating treatment to form a light-transmissive coating layer covering the protective film and the magnesium alloy substrate, wherein a thickness of portions of the light-transmissive coating layer located on the convex surfaces is smaller than a thickness of other portions of the light-transmissive coating layer located on the concave surfaces.
