Abstract

Per migliorare un procedimento per produrre un pezzo stampato (1) che presenta un'apertura d'alloggiamento (4) per un albero mediante sinterizzazione di uno sbozzato o pezzo greggio (5) stampato a partire da polvere di sinterizzazione e che forma un'apertura passante (6), con fase liquida, si propone che nell'apertura passante (6) dello sbozzato (5), una bussola (2) dimensionalmente stabile alle condizioni di sinterizzazione dello sbozzato (5), costituita da un materiale prodotto per fusione metallurgica, venga inserita con un gioco, che è minore dell'entità del ritiro dello sbozzato (5) che si verifica durante la sinterizzazione con fase liquida nella zona dell'apertura di passaggio (6), prima che lo sbozzato con la bussola (2) inserita venga sinterizzato con fase liquida.
