Abstract (en)
[origin: WO2007004241A1] A plant and a process are disclosed for producing components made of an aluminium alloy for vehicles and white goods, through the steps of: providing thixotropic billets made of an aluminium alloy; obtaining crop ends of material by sizing the billets; heating the crop ends in a range of temperatures during which both solid phase and liquid phase coexist with a prevalence in the solid phase (more than 50%) in heating furnaces (5); loading the heated crop ends in a die-casting machine (11) for products of the "Semi Solid Material" type; forming a molding with the die casting machine (11); extracting the molding; depositing the molding onto a conveyor belt (15); and controlling a quality of the obtained molding, sending then it to mechanical workings and/or an heat treatment; alternatively, previously cooling the molding in a tank (16); and depositing the cooled molding on a shearing die for shearing feedheads and/or risers.
