Abstract: A process for producing a molded part made of expanded foam is configured so that the molded part can be produced with low vacuum and vapor requirements and has a very low residual moisture. This is achieved by using a mold whose walls forming the mold cavity themselves consist of material that conducts heat poorly or are suitably coated, by first evacuating the mold cavity, filling the evacuated mold with the expandable molding compound at excess pressure and, after the filling operation, introducing vapor into the evacuated mold. After turning off the vapor pressure, the mold cavity is again evacuated and the vacuum is maintained during the stabilization phase. After the stabilization phase, the mold is opened and the molded part is ejected by excess pressure (FIG. 1).
