发明名称 METHOD FOR FORMING COMPACT FROM POWDER AND MOLD APPARATUS FOR POWDER MOLDING
摘要 A method for forming a compact from a powder wherein a forming portion 1A in a mold body 2 is filled with a raw powder and upper and lower punches 3,4 are fitted into the forming portion 1A to form the compact. Prior to filling the formin g portion 1A with the raw powder M, a solution L with a lubricant being uniformly dissolv ed in a solvent is applied to a peripheral portion of the forming portion 1A, and th en the solution is evaporated, thus forming a crystallized layer B thereon. Thus, t he reduction of a force for ejecting the compact is realized, while improving the density of the compact, realizing the stable and successive production of the compact</SDOA B>
