Abstract
Nello stampaggio di materiale plastico accoppiato, in particolare di polistirolo espanso in combinazione con polistirolo rigido in foglio, il materiale rigido (2) viene preformato, separando contemporaneamente la porzione preformata dal materiale di partenza, e la sagoma preformata viene trasferita nel semistampo di preformatura (33) alla fase di stampaggio, in cui il materiale espanso viene stampato per sinterizzazione ed azione impulsiva di vapore sul materiale rigido preformato. Il pezzo così ottenuto viene riportato alla stazione di preformatura (1) ed un'ulteriore porzione di materiale rigido (2) viene preformata sul materiale espanso e questa porzione viene poi fissata a caldo nello stampo di stampaggio (3) sul materiale espanso, dando così luogo ad un articolo con due superfici opposte di materiale rigido tra le quali è interposto il materiale espanso.
