8. A method for manufacturing a housing of portable electronic devices, comprising:
-
mixing laser activated substances with thermoplastic, the laser activated substances being insulating metallic oxides that when activated by laser decompose and generate metal; forming a blank using the thermoplastic with the laser activated substances mixed therein; engraving the blank using laser to form a decoration portion on the blank and activate the laser activated substances in the engraved part of the blank, such that the laser activated substances in the engraved part of the blank decompose and generate metal to form a metallic layer on the decoration portion, thereby forming a first casing; forming a decoration layer made of metal on the metallic layer by electroplating or chemical plating; and forming a transparent second casing on the first casing to cover the decoration layer. - View Dependent Claims (9, 10, 11, 12)
