Abstract

Ce procédé appliqué à la production d'un tube en polyéthylène haute densité, permet, en partant d'un mélange pulvérulent, de séparer nettement la phase de formage qui consiste à préformer par compression le fritter ensuite dans une filière chauffée, de la phase de réticulation qui s'opère au sein d'un bain de sel fondu 44 contenu dans une cuve horizontale 41, d'où le produit est extrait par la traction exercée par le dispositif 63.
