Abstract: A method for fabricating a spectacle frame made of a cellulose acetate sheet embedded with the metal piece, where the metal piece is embedded between a main material and auxiliary materials; the metal piece, the main material, and the auxiliary materials are tightly bonded by pressing by a hydraulic press. Since the metal piece is not in contact with a human body, there will be no corrosion problems. The composite plate structure resulting from splicing of the main material and the auxiliary materials have better mechanical performance.

Abstract: A method for fabricating a multi-color cellulose acetate spectacle frame, which includes: baking a multi-color cellulose acetate sheet so that it is soften; pressing so as to enable the second, third, and fourth color layers of the multi-color cellulose acetate sheet to move a distance greater than the thickness of a surface color layer of the multi-color cellulose acetate sheet; grinding off or shaving off a surface layer of the excessively moved portion so that the color of a middle layer is highlighted; baking the multi-color cellulose acetate sheet again so that it is soften; pressing so that the color of the middle layer is highlighted to the surface of the spectacle frame. According to the method for fabricating the multi-color cellulose acetate spectacle frame, the working processes are saved, and the qualification rate of product is improved.
