METHOD FOR MANUFACTURING CERAMIC RAZOR BLADE BY INJECTION MOLDING

摘要

The present invention relates to a method for manufacturing a ceramic razor blade using an injection molding method while having economic efficiency. The ceramic razor blade manufactured by the method of the present invention has an excellent cutting force, reduced weight, and hygienic since the ceramic razor blade is made of ceramic of fine particles and is easily manufactured using an injection molding method to reduce manufacturing costs as compared with the existing steel razor blade or the existing ceramic razor blade made by using a press molding method. Moreover, a core unit of the ceramic razor blade has high hardness and a surface of the ceramic razor blade has high toughness. Therefore, the present invention can restrain surface damage while maintaining overall high strength of the razor blade and removes structural non-uniformity inside the razor blade to prevent bending of the razor blade.
