Method and Device for Producing a Particle Foam Part
This invention concerns a process for producing particle foam part in which foam particles are heated in a molding tool so that they weld to the particle foam part. Heat is supplied to the foam particles by means of electromagnetic RF radiation. The foam particles are made of polyurethane (PU), polylactate (PLA), polyethylene block amide (PEBA) or polyethylene terephthalate (PET).
Device and Method for Producing a Particle Foam Part
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.
Induction welding of thermoplastic with metallic strips
Methods and apparatus' for induction welding a first workpiece to a second workpiece at a welding region may include a metallic strip. The metallic strip may be a mesh. The properties of the metallic strip, such as, for example, pore size, thickness, and density, may be configured to conduct heat uniformly across the welding region and prevent eddy current formation across a workpiece. The metallic strip may be embedded in a workpiece or may be fixed to an induction welding tool that acts on the welding region during induction welding. A removable polymer tape may be disposed between a workpiece and a metallic strip fixed to an induction welding tool. The workpieces may be thermoplastic composite structures and thermoplastic composite stiffeners in aircraft structures.
