Abstract
The invention relates to a method and a device for producing a particle foam part. The device comprises a molding tool (3) which delimits a molding chamber (14), wherein at least two capacitor plates (15, 16) are arranged adjacently to the molding chamber, said plates be connected to an RF radiation source. The RF radiation source is designed to dispense RF radiation, and the molding tool (3) has means for controlling the temperature of the molding tool in the region of an inner delimiting surface (19) delimiting the molding chamber (14) and/or for supplying a heating medium to the molding tool region lying against the inner delimiting surface.
Claims24
A method for producing a particle foam part, the method comprising:
- heating foam particles, which are formed from an expandable thermoplastic polymer material, in a molding chamber of a molding tool, welding the foam particles into the particle foam part, the foam particles being heated by electromagnetic radiation,
- wherein the foam particles are heated to a temperature of at least 160° C., wherein the foam particles are first preheated to a predetermined temperature and then heated at the predetermined temperature by direct absorption of the electromagnetic radiation by the foam particles to a higher temperature.
