Innovative technologies for processing light metal alloys have undergone enormous development in recent years. These include rheocasting – a special casting process in which aluminium in a semi-solid state is processed into lightweight components with special material properties.
SAG is the technology leader in rheocasting – a special casting process in which aluminium is cast in a semi-solid or semi-liquid state. This so-called semi-solid process has many advantages.
SAG is the only manufacturer in the world to produce rheocasting components such as safety cabin suspensions for trucks or air reservoirs in series production for the automotive industry. The demand for the light and particularly robust components is increasing strongly and the production capacities at the SAG location in Lend have recently been expanded considerably thanks to great demand from the passenger car industry. A total of more than EUR 3.6 million was invested in the expansion of the rheocasting facilities.
At the SAG plant in Sweden, more than 250,000 rheocasting components are produced annually in 3-shift operation for large truck manufacturers such as VOLVO and Scania.
In Lend/Salzburg, special components for the automotive industry are produced using the rheocasting process.
Because with only 3 parts (example: truck cab suspension) up to 120 kg weight – compared to steel parts – can be saved, thus reducing fuel consumption and saving an average of 0.3 tons of CO2 per year and truck).
Rheocasting thus offers a total package of advantages, for which VOLVO has awarded an innovation prize to SAG in 2018.
