The enamel layer mainly contains silicon oxide, aluminum oxide, sodium oxide, potassium oxide, and fiber reinforced composite. A method for making the coated article is also described.
Abstract:
A plastic composite comprises a first plastic substrate, an adhesive layer formed on the first plastic substrate, and a second plastic substrate formed on the adhesive layer. The first plastic substrate is made of thermoplastic resin material. The second plastic substrate is made of thermosetting resin material. The adhesive layer mainly comprises amino silane coupling agent. A method for manufacturing the plastic composites is also provided.
Abstract:
Housing of electronic device includes a metal base and a ceramic pattern portion formed in the exterior surface of the base; The pattern portion is formed by etching of base and enamel of the etched area of the base. The disclosure also described a method to make the housing.
Abstract:

The window frame has a internal surface and a peripheral wall; The first housing unit integrally joins to the peripheral wall of the window frame by injection molding; The second housing unit integrally joins to the internal surface of the window frame to form a window area, the second housing unit integrally joins to the internal surface of the first housing unit.
Abstract:
A housing includes a screen guard defining a transparent section, and a main body molded to the screen guard. The screen guard and the main body cooperatively define a cavity for accommodating electronic components of the electronic device.
Abstract:
An electronic device housing includes a plastic substrate. The plastic substrate includes a first surface. The electronic device housing further includes an activating layer formed on the first surface. The activating layer contains metal powder. The activating layer defines a recessed portion. Some of the metal powder is partially exposed on the surface of the recessed portion. Some of metal powder is partially inserted into the plastic substrate corresponding to the recessed portion. The electronic device housing further includes an antenna layer formed on the recessed portion. The antenna layer is a metal layer. A method for manufacturing the electronic device housing is also disclosed.
Abstract:
A method for making patterns on a metal article comprises providing a metal substrate having an outer surface. A light-absorbing coating is formed on selected regions of the outer surface to reduce the surface laser reflectivity of the metal substrate. The selected regions cooperatively have a shape of a desired pattern. The selected regions are treated by laser-quenching, thereby hardening the selected regions. The outer surface is sandblasted, enabling the outer surface besides the selected regions to have a greater surface roughness than the selected regions. A metal article made by the method is also provided.
Abstract:
A device housing includes a stainless steel substrate having a first metallic coating and a second metallic coating formed thereon and in that order. The stainless steel substrate has at least one recess defined in an outer surface. The first metallic coating and a second metallic coating have different colors. The first metallic coating is left exposed in the recesses but covered elsewhere by the second metallic coating to form a desired symbol, logo, or pattern on the device housing. A method for making the present device housing also is provided.
Abstract:
A housing includes a hollow sleeve, a top wall, and a cover. The top wall is integrally formed with the hollow sleeve. The top wall seals an end of the hollow sleeve to define a receiving chamber. An open end is formed at an opposite end of the top wall. The open end communicates with the receiving chamber. The hollow sleeve and the top wall include a transparent first molded article, a decorative layer, and a transparent second molded article. The decorative layer partially is formed on the transparent first molded article, and a transparent display window of the transparent first molded article is exposed from the decorative layer. The transparent second molded article is formed on the decorative layer and the transparent display window. The cover seals the open end. The present disclosure further discloses a method for making the housing.
Abstract:
A lens cover slidably mounted to a lens comprises a main body and two guide plates protruding from opposite sides of the main body. Each guide plate has a plurality of contact portions. Each contact portion includes a plurality of projection strips protruding from a surface thereof and facing the lens.
