Abstract: An appearance mechanical part includes a substrate formed by jointing a metal component and an insulation component and an insulation appearance layer formed on a surface of the substrate and covering a jointed boundary line. The jointed boundary line is a boundary line formed by the metal component and the insulation component on the surface of the substrate. A corresponding method for manufacturing the appearance mechanical part is provided. According to the appearance mechanical part and the method, the jointed boundary line is covered by an insulation appearance layer, so that a color and gloss of a surface of the appearance mechanical part can be consistent, and structural strength of the appearance mechanical part can be increased.

Abstract: The present disclosure relates to a waterproofing method for an electronic device. In one example method, silane is coated on an inner wall of a first housing of the electronic device and an inner wall of a second housing of the electronic device. The first and second housings and a main board of the electronic device are assembled. Fluoride is injected into a cavity of the electronic device through a liquid inlet hole on the first housing. An integral continuous waterproofing membrane is formed on the inner walls of the first and second housings through chemical reaction between the silane and the fluoride.
