Abstract

Pressa per la formatura di oggetti con materiale ceramico in polvere comprendente un basamento (3) portante uno stampo ceramico, una traversa superiore fissa (l), una traversa superiore mobile (2) portante i punzoni superiori di detto stampo, primi mezzi (10) di azionamento per il sollevamento e l'abbassamento di dette traversa superiore mobile, nella quale tra detti primi mezzi di azionamento (10) e detta traversa mobile (2) sono interposti secondi mezzi di azionamento (20), indipendenti dai primi, e costituiti da un gruppo cilindro-pistone (21 - 22) avente una corsa non maggiore della corsa necessaria alla pressatura del materiale nello stampo; essendo previsti mezzi atti ad alimentare almeno una volta, dopo il completo abbassamento della traversa superiore mobile, detti secondi mezzi di azionamento (20) mediante liquido di azionamento avente portata tale che il raggiungimento della pressione massima avviene in un tempo preferibilmente inferiore aventi millisecondi.
