The extrudate 3 seals the joint between the half-shells 5a and 5b.
  • FIG. 5 shows a plastic component 1 in one exemplary embodiment with a cover layer 6.
  • the cover layer 6 is disposed on a surface of the component blank 2 and / or of the
  • Plastic component 1 is arranged.
  • the cover layer 6 is formed from a thermosetting plastic.
  • the cover layer 6 is arranged in this embodiment only on one side.

  • Component blank 2 in particular with the foamed plastic, connected.
  • FIG 6 shows an embodiment of the plastic component 1, wherein the
  • Plastic component 1 has two cover layers 6 in this embodiment.
  • Cover layers 6 are on different, opposite sides of the
  • Component blanks 2 arranged.
  • the cover layer 6 is notched on one side.
  • the notching can be done mechanically, for example with a saw, furthermore, the notch can be introduced by means of a laser.
  • the continuous filament is extruded into the indentation.
  • the extrudate 3 comes into contact with the foam plastic of the component blank 2, can melt it and into the foam plastic or the

  • the extrudate temperature of the extrudate 3 is chosen so that the extrudate 3 is flush with the cover layer 6.
  • FIG. 7 shows an exemplary embodiment in which two component blanks 2 are joined together by means of the extrudate 3 to form a common plastic component 1.
  • the component blanks 2 are arranged so that between the component blanks 2, the continuous filament can be extruded.
  • the hot extrudate 3 sinks into both component blanks 2 and connects to them in each case materially.
  • the extrudate 3 then holds the two component blanks 2 together in the plastic component 1.

Abstract

L'invention concerne un procédé de fabrication d'un composant en plastique (1) comprenant les étapes suivantes : la fabrication d'une ébauche (2) de composant à partir d'un plastique alvéolaire, l'extrusion d'un filament continu, qui forme un extrudat (3), sur l'ébauche (2) de composant, l'application de l'extrudat (3) d'une température d'au moins 85 degrés Celsius sur l'ébauche (2) de composant, ce qui a pour effet qu'une partie du plastique alvéolaire et/ou une surface de l'ébauche (2) de composant est fondue, ce qui a pour effet que l'extrudat (3) est assemblé à l'ébauche (2) de composant. Un composant en plastique (1) peut être obtenu par le procédé.
