Abstract
Le procédé concerne la fabrication d'envelopppes en matière plastique productrices d'éclats métalliques qui sont projetés vers l'extérieur lors de l'explosion. On introduit dans un moule creux 20 de la poudre de matière plastique 33 et des particules métalliques 12. On donne au moule un mouvement tournoyant autour d'au moins deux axes de rotation, et on le fait baigner dans un fluide chaud. On obtient un corps creux en matière plastique sur la face interne duquel adhèrent les particules métalliques 12. Application en particulier à la fabrication des grenades, mines et analogues.
