Beschreibung
Zusammenfassung:	Manufacture of an article from thermoplastic sandwich material with a cellular core and having a thermoplastic interior part is by draping the material over the cavity of a female mold part. Then some thermoplastic is placed on a depression in the draped material. The material is then forced vertically against the surfaces of the cavity and gripped around the edge of the cavity. Independent claims are included for the following: (a) In the above method forcing of the material into cavity produces heat and pressure to fuse the sandwich material and the thermoplastic together. The complete article s removed from the mold and excess material removed from its edges. (b) Molding system as above. (c) Article produced as above. L'invention concerne un procédé et un système pour mouler ensemble un matériau thermoplastique et un matériau sandwich thermoplastique.Le système (10) comprend un outil femelle (14) présentant une cavité (16) de définition d'article et un outil mâle (20) destiné à introduire à force une partie intérieure d'une ébauche d'un matériau sandwich thermoplastique ayant une âme cellulaire et une quantité prédéterminée d'un matériau composite thermoplastique placée sur l'ébauche dans l'outil femelle suivant un axe sensiblement vertical et contre les surfaces intérieures (18) de la cavité afin d'obtenir un matériau sandwich profondément embouti.Domaine d'application : fabrication de pièces à structure sandwich telles que des compartiments pour roues de secours, etc.
