PROCESS FOR THE PRODUCTION OF STRUCTURAL THERMOINSULATING ELEMENTS AND ELEMENTS SO OBTAINED

摘要

Process for the production of thermoinsulating structural elements, whi ch includes: a)producing by thermoforming a cell made of thermoplastic material; b)pulling on such cell on a male die half shell; c)closing the die with a negative half shell suitable to form a cavity betwe en the half shells, d)inserting ,in the cavity bored hollow elements e)filling the cavity with foamed pearls in thermoplastic polymers; f)sintering the pearls with steam fed through hollow elements. g)cooling and extracting the hollow elements h)extracting the structural element from the die.
