Abstract (en)

[origin: WO2018095572A1] In order to produce a molded part consisting of a particle foam, plastic particles are introduced into a molded part cavity (K) and are foamed and/or sintered in the molded part cavity by supplying thermal energy. The thermal energy is introduced by means of multiple radiowave transmitters (24) and multiple fluid temperature control systems (15, 15a). The radiowave transmitters (24) introduce radio waves into the molded part cavity (K) and can be actuated independently of one another by a controller (13). At least one sub-tool which delimits the molded part cavity (K) is heated to partly desired temperatures by means of the fluid temperature control systems (15, 15a), and the fluid temperature control systems (15, 15a) are actuated independently of one another by the controller (13).
