PURPOSE:To provide a press-forming mold having excellent mirrorpolishing workability, nonreactivity with molded product, easy processability and high impact resistance. CONSTITUTION:The objective press-forming mold is composed of a substrate 1, a forming face 2 formed on a part of the surface of the substrate and a sliding face 3 formed on another part of the surface of the substrate. The substrate 1 is composed of a sintered porous ceramic material, the forming surface 2 is covered with a dense SiC film 11 and the sliding face 3 has a slide- protection layer 13 composed of a dense inorganic material layer or an impregnated layer produced by impregnating an inorganic material in the porous ceramic material constituting the substrate. |
