Abstract
Disclosed are a dual surface-treated injection molding article, which is manufactured by dually surface-treating an injection molding substrate formed of a light-transmissive semi-transparent or transparent material in such a manner that a metallic appearance is expressed or any of a logo, a pattern, an ornamental design, and a picture is formed on each of inner and outer surfaces of the injection molding substrate, and a method of manufacturing the same.
Claims20
A dual surface-treated injection molding article, comprising:
- a first physical vapor deposition layer formed on the inner surface of an injection molding substrate of the type having a light-transmissive semi-transparent or transparent material;
- a first print layer formed by etching or removing the first physical vapor deposition layer;
- a first paint layer formed on the inner surface of the injection molding substrate;
- a masking layer formed on the outer surface of the injection molding substrate;
- a second physical vapor deposition layer formed on the outer surface of the injection molding substrate at an area exposed the masking layer;
- a second print layer formed by etching or removing the masking layer;
- and
- a second paint layer formed on the outer surface of the injection molding substrate.
A method of manufacturing a dual surface-treated article, comprising:
- forming a first physical vapor deposition layer on the inner surface of an injection molding substrate, which is formed from a light-transmissive semi-transparent or transparent material;
- forming a first print layer by etching or removing the first physical vapor deposition layer;
- forming a first paint layer on the inner surface of the injection molding substrate;
- forming a masking layer on the outer surface of the injection molding substrate;
- forming a second physical vapor deposition layer on the outer surface of the injection molding substrate at an area exposed through the masking layer;
- etching or removing the masking layer and forming a second print layer;
- and
- forming a second paint layer on the outer surface of the injection molding substrate.
A portable communication device, comprising:
- a housing having an injection molding substrate formed from a light-transmissive semi-transparent or transparent material, the injection molding substrate including:
- a first print layer formed on the inner surface thereof;
- a first paint layer covering the first print layer;
- a second print layer formed on the outer surface of the injection molding substrate and at opposite end of the first print layer;
- and
- a second paint layer covering the second print layer.
