A case frame used in various devices and a method of manufacturing the case frame are provided. The method includes forming the case frame in a shape corresponding to a product to which the case frame is applied, forming a first painting layer with a color of a material applied to a surface of the formed case frame, depositing a transparent oxide deposition layer having a refractive index on an upper portion of the first painting layer, and forming a second painting layer on an upper portion of the transparent oxide deposition layer. Accordingly, the case frame can have an excellent texture by reproducing a brightness and a color anisotropy on the basis of a viewing angle by adding only a simple manufacturing process, thereby being able to improve quality of an electronic device in general and to promote a user's desire for purchasing the device.

Case frame and manufacturing method thereof

A case for an electronic device includes an injection preform having a recess on at least one portion of a surface thereof, a deposition layer deposited on a surface of the injection preform, and a paint layer formed on the deposition layer. The deposition layer may directly contact a surface of the injection preform. A method of manufacturing a case includes injection-molding an injection preform having a recess on a surface thereof, forming a deposition layer directly contacting a surface of the injection preform, and forming a paint layer on the deposition layer.

Case, method of manufacturing case, and electronic device

An electronic device and a method for manufacturing an outer housing of the electronic device are provided. The electronic device includes an outer housing including a portion including a base including a non-conductive material and a plurality of islands formed on or above the base, wherein the plurality of islands include metallic materials, wherein the plurality of islands are spaced apart from each other, and wherein the plurality of islands form a two-dimensional (2D) pattern. The method includes injection-molding a base and forming a plurality of islands on or above the base, wherein the plurality of islands include metallic materials, and wherein the plurality of islands are spaced apart from each other to form a 2D pattern.

Electronic device and method for manufacturing the same

A method for finishing an exterior surface of an injection-molded product is provided, in which a metal layer is formed on the exterior surface of the injection-molded product, a photoresist layer is formed on the metal layer, a photomask is placed on the photoresist layer, light is projected onto the photomask, and remaining parts of the metal layer and the photoresist layer except for parts corresponding to a pattern formed on the photomask are removed by etching.
