<p>A method of molding the powder of a metal, ceramic or the like which comprises preparing a plastic mold having at least one opening on the surface of a pattern having a desired form to be molded, removing the pattern to form a cavity on the plastic mold, filling a molding material of metal powder, ceramic powder or the like into the cavity through the opening, sealing the cavity, and treating the mold with cold isostatic pressing. In the method of the invention, by using a plastic material for the mold, the external liquid pressure is transmitted to the molded body therein, and an isotropic pressure is added to the molded body during the cold isostatic pressing. According to the method of the invention, the time for preparing a mold can be shortened to about 1 hour from 5 to 20 hours which is taken in the previous method. <IMAGE></p> |
