Abstract

La présente invention est relative à un dispositif et à un procédé de fabrication d'objets à parois minces en matière plastique expansée. Ce dispositif est caractérisé en ce qu'il comprend en association avec un moule à empreinte en métal présentant des pertes par courants de Foucault, au moins un circuit inducteur noyé dans la masse de la matière plastique à ramollir et relié à un ou plusieurs générateurs du courant haute-fréquence (HF), ledit circuit se trouvant à une distance de 0,05 à 2 mm de l'empreinte du moule. Application à la fabrication d'objets à parois minces (tels que gobelets, barquettes, etc.) en matière plastique expansée.
