Abstract
The invention relates to an apparatus for the manufacture of a particle foam component, said apparatus comprising a molding tool limiting a molding space, wherein, adjacent to the molding space, at least two capacitor plates are arranged which are connected to a radiation source for electromagnetic radiation, wherein the radiation source for electromagnetic radiation is designed for emitting electromagnetic radiation, and wherein the molding tool is formed of at least two molding halves, wherein at least one of the molding halves is made from an electrically conducting material and forms one of the capacitor plates.
Claims19
Apparatus for the manufacture of a particle foam component, comprising:
- a material container containing foam particles;
- a filling injector for applying compressed air to flow the foam particles from the material container;
- a radio frequency radiation source for generating radio frequency electromagnetic radiation;
- a molding tool that limits a molding space and that is configured for tempering a surface limiting the molding space, wherein adjacent to the molding space, at least two capacitor plates are arranged which are connected to the radiation source for the electromagnetic radiation;
- the molding space receiving the flow of the foam particles from the filling injector;
- and the molding tool is formed of at least two molding halves, wherein the at least two molding halves define the molding space each by means of an inner boundary surface and at least one of the at least two molding halves is made from an electrically conducting material and forms one of the capacitor plates, wherein at least one inner boundary surface of the electrically conducting material has an inner boundary surface with a contoured configuration which deviates from a planar surface and the radio frequency radiation source applies electromagnetic RF radiation to the molding space via the capacitor plates to heat and weld the foam particles into the particle foam component, wherein one of the at least two molding halves has a passage opening for introducing the foam particles from the filling injector, the passage opening being covered up by another of the at least two molding halves in a closed state of the molding tool.
