The invention relates to a method for manufacturing at least partly plastic vehicle parts in a mold (50) with at least one mold cavity (55), comprising the steps of: at least partly closing the mold, wherein the at least one mold cavity is brought in a first position by means of at least one movable wall part (53) of the at least one mold cavity; introducing plastic into the at least one mold cavity; upon complete closure of the mold and/or movement of the at least one movable wall part, bringing the at least one mold cavity in a second position, the at least one mold cavity in the second position having a different volume than in the first position; all this in such a manner that by bringing the at least one mold cavity from the first into the second position, the plastic fills the respective mold cavity completely.

L'invention concerne un procédé permettant de fabriquer au moins partiellement des parties en plastique de véhicules dans un moule, au moyen d'au moins une cavité du moule, et comprenant les étapes consistant : à fermer au moins partiellement le moule, la cavité du moule étant amenée dans une première position, au moyen d'au moins une partie d'une paroi mobile de ladite cavité ; à introduire le plastique dans ladite cavité ; au moment de la fermeture totale du moule et/ou du déplacement de la partie de la paroi mobile, à amener la cavité du moule dans une seconde position où le volume de celle-ci est différent de celui dans la première position ; et à faire passer la cavité du moule de la première à la seconde position de manière telle que le plastique remplisse totalement la cavité du moule respective.
