ABSTRACT:
This invention relates to a method of producing a mold for use as a part of a tool for shaping of moldable material and having relatively high strength and heat resistance characteristics. According to the invention there is formed a porous body of sinterable material in contact with a pattern to form a material shaping surface on the body; the body when still in contact with the pattern surface is sintered and the sintered body is at least partially filled with infiltrating material having a melting point lower than that of the sintered body. The infiltrating step is effected in such matter that the pores of the surface of the sintered body in contact with the pattern surface are filled by infiltrating material from the side of the body opposite to the pattern surface whereby also the infiltrating material which fills the pores of the sintered body in the surface thereof is formed by the pattern surface.
