摘要

Process for thermally homogenizing pressing tools, especially plungers comprises inserting a tin solder into the hollow chamber of the tool. An Independent claim is also included for a plunger used for carrying out the homogenizing process comprising a plunger body (2, 3) formed as a hollow body with the hollow chamber (4) filled with tin solder having a melting point of approximately 190 deg C and an expansion space (5), and a double tube arrangement (6, 7) acting as a liquid vaporizing device extending into the hollow chamber. Preferred Features: The double tube arrangement consists of an outer tube (6) closed on one end for introducing the medium to be vaporized and a central tube (7) for removing the vapors.
