Zusammenfassung:	The tools consisting of a punch (20), die (10) and clamping plate (30) are made of epoxy resin concrete and are provided with a metal envelope (25, 15, 35), the metal envelopes themselves being formed by stamping using a master mould and its counter mould coated with sized wax layers or uncoated. The die envelope is produced, in particular, by welding the two complementary half-moulds. Les éléments de l'outillage, poinçon (20), matrice (10) et serre-flan (30), sont constitués de béton en résine époxy et recouverts d'une enveloppe métallique (25, 15, 35); les enveloppes métalliques sont elles-mêmes obtenues par emboutissage au moyen du maître-modèle, et de son contre-moulage, revêtu ou non de couches de cire calibrées; l'enveloppe de la matrice est notamment obtenue par soudure de deux demi-enveloppes complémentaires.
