摘要:
In a method of manufacturing dry-pressed molded articles from essentially dry, pourable ceramic metal or carbon-containing molding compound in a mold of one or more parts, it is proposed to generate a negative pressure through the mold wall in the hollow space of the mold and, by means of the pressure difference generated as a result, to propel molding compound which is under pressure, for example, atmospheric pressure, through an injection opening into the hollow space of the mold and to precompress the molding compound in the mold while deaerating the molding compound, and that subsequently, the pneumatically precompressed molding compound is compression molded into a molded article having the desired final density.
