  • Publication number: 20030045212
    Abstract: The present invention relates to a front sheet of a microwave oven and a method for manufacturing the front sheet. The method for manufacturing the front sheet of the microwave oven according to the present invention comprises a first process including a chemical polishing process of removing foreign materials from and polishing a surface of an aluminum sheet so as to give a predetermined luster thereto; a process of forming a porous anodic oxide film onto the surface of the aluminum sheet; a process of dipping the aluminum sheet into a solution containing a dye and penetrating the dye into a porous film of the anodic oxide film; and a process of sealing the porous film into which the dye has been penetrated. The microwave oven according to the present invention includes a colored front sheet manufactured by anodizing and dyeing the surface of the aluminum sheet and attached to a front face of a door portion or a control panel portion of the microwave oven.
