Diecastings for high performance applications.

Issued at 2013-06-12



The aspects that determine and improve the performance of diecastings will be analysed during the study day that the Diecasting Study Centre of the Italian Association of Metallurgy will devote to "Getti pressocolati per prestazioni elevate" (Diecastings For High Performance Applications). The meeting will be held on June 21st 2013 in Castel San Pietro Terme (Bologna) at Rifimpress offices and will involve academic and above all industrial experts that will describe the sector state of the art as for the production of diecast structural parts and will propose their history case in order to explain the opportunities that the diecasting sector can offer through the adoption of suitable strategies and solutions.

The meeting chairpersons will be Annalisa Pola of DIMI, University of Brescia; Mario Rosso, Politecnico of Turin; and Gianluigi Chiarmetta - Consultant, Turin. In the last years, the demand of diecastings for high performance applications is urging the metallurgical and technological sectors to look for and test new process solutions enabling the production of porosity-free parts that can be heat treated thus having clear and certain advantages in terms of production frequency and cost effectiveness.

As far as the production of structural diecastings is concerned, several aspects have to be taken into account: first of all the mechanical requirements that the structural diecastings have to meet to allow for the choice of the best high-performance alloys; then hardening and ageing parameters are crucial to exalt even further the characteristics of the diecast pieces. Anyhow the diecast part quality cannot leave out of consideration the improvement of the foundry process leading to the gas porosity elimination or, at least, reduction. That's why several technological processes have been developed such as semisolid casting or vacuum casting.
