    • PURPOSE: A zirconia ceramic case manufacturing method for a portable electronic device having a logo with an excellent sense of beauty is provided to prevent the twisting phenomenon of a logo shape by equalizing the sintering shrinkages of a zirconia case and a logo during a sintering process. CONSTITUTION: A zirconia ceramic case manufacturing method for a portable electronic device is composed of the following steps of: the step of molding a zirconia case molded article; the step of molding a logo with a zirconia material having the same compounds as the zirconia case molded article except color additions; the step of forming an intaglio on a press mild; the step of pressing the zirconia case molded article placed on the logo after the logo is placed on the intaglio; the step of sintering the zirconia case molded article; and the step of polishing the surface of the sintered zirconia case. The logo is molded with a thickness more than the depth of the intaglio of the press mold. The step of surface-polishing is implemented for the surfaces of the log and the zirconia case mold to have the same level of the surfaces.
    • 目的:提供一种具有良好感觉的标志的便携式电子设备的氧化锆陶瓷盒制造方法,以通过在烧结过程中平衡氧化锆壳体和标志的烧结收缩率来防止标志形状的扭曲现象。 构成:用于便携式电子设备的氧化锆陶瓷盒制造方法包括以下步骤:模制氧化锆壳模制品的步骤; 用与氧化锆壳模制品相同的化合物的氧化锆材料模制标志的步骤除了添加颜色; 在印刷机上形成凹版的步骤温和; 将标志放置在凹版上之后,将放置在标志上的氧化锆壳模制品按压的步骤; 烧结氧化锆壳模制品的步骤; 以及抛光氧化锆烧结体的表面的步骤。 该标志的成型厚度大于压模的凹版深度。 对于木材和氧化锆壳模具的表面实施表面抛光的步骤以具有相同水平的表面。
