METHOD FOR MANUFACTURING A ZIRCONIA CERAMIC CASE FOR PORTABLE ELECTRONIC DEVICES CAPABLE OF IMPROVING ENDURANCE TO IMPACTS AND DIMENSION PRECISION

摘要

PURPOSE: A method for manufacturing a zirconia ceramic case for portable electronic devices is provided to reduce the weight of the case and to improve the impact resistance characteristic of the case by adequately arranging reinforcing members at the edge of a base.;CONSTITUTION: A method for manufacturing a zirconia ceramic case for portable electronic devices includes the following: a base(100) is formed; a reinforcing member(110) is formed; The reinforcing member is arranged at the edge or around the opening of the base to obtain a zirconia case mold; the zirconia case mold is pressed under constant pressures; the pressed zirconia case mold is sintered. Parts of the corners of the zirconia case mold are eliminated before the pressing process under the constant pressures.;COPYRIGHT KIPO 2012
