Abstract
The pressure casting of aluminium alloy A356 is a metallurgical technique that provides a very high quality of the final product, because it avoids defects in the filling of the mould and consequent solidification, typical for the traditional casting process. The semi-solid metal shows excellent injection characteristics, if the required uniform temperature distribution is assured. The paper presents the last results achieved at the Padua University and ATE srl in the domain of research activity aimed at development of an induction system for re-heating thixocasting billets and maximisation of its performance. The system allows significant reduction of the heating times and higher production rates.
