Abstract

Un procedimento per la realizzazione di corpi di materiale polimerico comprende l'estrusione di un elemento tubolare (parison) ed il suo soffiaggio contro le pareti di uno stampo mediante introduzione all'interno dell'elemento tubolare di un materiale polimerico espandibile atto a costituire il nucleo espanso del corpo.(Fig. 6)
