MULTIPLE CERAMICS RAZOR BLADES AND MANUFACTURING METHOD FOR THE SAME

摘要

PURPOSE: Multiple ceramic razor blades and a manufacturing method thereof are provided to lighten the weight of the ceramic razor blades compared to metal razor blades and to prevent the propagation of germs. CONSTITUTION: A manufacturing method of multiple ceramic razor blades is as follows. A zirconia ceramic sintered body is manufactured(S600). The molding body of multiple razor blades is molded by injection-molding the zirconia ceramic sintered body(S700). The top and bottom surfaces of the molding body are flattened(S800). The razor blades are lapped to have sharp edges on the blades(S900). The ends of the razor blades are processed in a wave shape(S1000).
