摘要：The material is sintered in a mould cavity (FH), which is enclosed by mould walls
(FW1, FW2) of material of low thermal conductivity and low thermal capacity, for exampleplastic, which walls are surrounded by chambers (K1, K2) which are connected to themould cavity (FH) by steam openings (DD), via which the virtually saturated steam is fedfrom a steam generator (DG) via a steam valve for the purpose of heating to the sinteringtemperature, the steam condensing in the plastic material during sintering. Subsequently,by means of negative pressure for the purposes of cooling the condensate is evaporatedand drawn off into an injector cooling chamber (KK) and a vacuum source (VB, VP). Anapparatus for carrying out the method and the control means are specified.
