Abstract

L'invention concerne un procédé permettant de mouler des éléments minces formés de plastiques de polyuréthanne à un seul composant. Ce procédé consiste à déposer lorsque le moule (116) est encore au moins partiellement ouvert le matériau de plastique fluide dans les diverses zones de la partie (118) inférieure du moule (116), à raison d'une quantité proportionnelle à la largeur de l'empreinte puis à fermer le moule (116), à compresser le matériau fluide et à laisser refroidir l'ensemble.
