MANUFACTURING METHOD FOR MOLDING OF LIGHT-REFLECTION DOOR FRAME

摘要

The present invention provides a method for manufacturing molding of a half gloss aluminum door frame which is capable of increasing corrosion resistance and reducing prime cost in comparison with existing technique by applying an aluminum material which multi-layer coating is applied to instead of a half gloss material as a material used for conventional door frame molding. According to the present invention for achieving the above purpose, a method for manufacturing molding of a half gloss aluminum door frame which is capable of reducing prime cost and increasing corrosion resistance comprises: a step for forming an oxide film on a surface of a metal plate in an anodizing treatment after cutting the metal plate in a certain size; a step for forming a half gloss in an opaque clear coating treatment and a transparent coating treatment of the metal plate having the oxide film; and a step for press forming the metal plate where the oxide film and the half gloss are formed as a door frame molding form.
