Rheocasting a cost effective casting process for light alloys

CSIR has patented a rheocasting system for the preparation of semi-solid slurries, which is available for commercial production. This process stems from a recent trend in the automotive industry to produce fuel-efficient vehicles through the use of aluminium and magnesium alloys. The bulk of the automotive industry’s needs in this
regard are satisfied through the use of liquid metal, high-pressure die casting (HPDC). The growing demand for improved quality and weight reduction is driving the development of new processing technologies. The problems inherently associated with liquid metal HPDC led to increased interest in semi-solid metal casting processes, which in turn led to the development of rheocasting. More
