Provided are a cover having a metallic grid structure and a method for manufacturing the cover. The cover includes a pattern portion formed of a metallic material, in which a plurality of patterns are independently disposed spaced apart from each other and an injection portion disposed between pattern portions to connect the pattern portions, the injection portion being formed of a non-metallic material. The method includes forming a pre-pattern portion including patterns in a regular or irregular form and a bridge connecting the patterns on a metallic plate, forming the injection portion on the pre-pattern portion by insert-injection or thermo-compression press, and removing the bridge.

Cover having metallic grid structure and method for manufacturing the cover

A method of fabricating a case for a portable electronic device includes: preparing a case preform; processing the inner surface of the case preform using a laser; and surface-treating the outer surface of the case preform, wherein the outer surface of the case preform shows fine prominences and depressions formed by the surface-treating of the outer surface of the case preform, and patterns formed by processing the inner surface of the case preform appear bumpily on the outer surface of the case preform.

Method of fabricating case for portable electronic device

Provided is an injection-molded product manufactured of a synthetic resin having light permeability, the injection-molded product including a pattern structure formed on an inner surface of the injection-molded product and a coupling structure formed on the pattern structure, in which the coupling structure is hidden by the pattern structure from an outer surface of the injection-molded product. The injection-molded product may be manufactured of a transparent material so that the coupling structure or reinforcing structure, can be hidden visually. Various colors can be used in the surface treatment, such as painting or deposition, on the injection-molded product.

Injection-molded product with permeability

A keypad for an electronic device having metallic texture has rigidity and elasticity equivalent to those of stainless steel. The keypad is manufactured and includes a metal alloy board, a keypad body manufactured by primarily thermal-treating the metal alloy board to a rigidity enough to be molded and molding the primarily thermal-treated metal alloy board with a press, a button portion formed by secondarily thermal-treating the keypad body to cure the keypad body and etching the secondarily thermal-treated keypad body by means of etching processing, and urethane rubber and a silicon pad attached to a back surface of the keypad body which has undergone anodizing processing and various colorations.

Keypad for electronic device and method for manufacturing the keypad

Disclosed is a manufacturing method of a keypad for a mobile phone and the keypad manufactured thereby, in which a vacuum deposition layer and a cellophane paper are attached to a lower surface of a key in the keypad. The keypad for a mobile phone includes a plurality of keys, each key includes a key body of a transparent resin material and a high-hardness transparent coating layer coated onto a surface of the key body in order to increase hardness, and each key comprises a key background color paint layer for color presentation, coated onto a lower surface of the key body; an opaque paint layer coated onto a lower surface of the key background color paint layer; a transparent marking portion formed by performing a laser processing according to a shape of a numeral, a character, or a symbol with respect to the lower surface of the key body so as to remove the color paint layer and the opaque paint layer; a metallic vacuum deposition layer formed on the lower surface of the key body and a lower surface of the opaque paint layer; and a transparent color-printed layer or a cellophane paper attached to a lower surface of the metallic vacuum deposition layer so as to present various colors.
