The present invention relates to a process for the production of moldings from foamable thermoplastics, especially from foamable polystyrene foam, in which pre-foamed plastic granules are post-expanded and sintered together in a mold with the supply of heat, a vacuum being applied to the mold before this is filled with the pre- foamed plastic granules and the mold being pre-warmed from the outside, characterized in that a hot inert gas is passed into the mold during or after introduction of the pre-foamed plastic granules in order to warm the granules. |
