Thixoforming is a semi-solid process to obtain the thixotropic structure. The effective use of the semisolid process presumes good knowledge of the rnaterial behaviour. The paper presents some experimental data about the thixoforming process applied to aluminum alloy ATSi5Cu1, very used in the Romanian machine building industry. From many procedures for obtaining the semisolid slurry described in the paper, based on  specialized literature [2, 3, 4] in particular, the accent is given to choose the mechanical mixture in the overheated mould until it reached the liquid alloy temperature. The main results are based on reducing of stirring time for increasing the benefits of the new technology. All procedures and results are described in the paper and also some specific conclusions are given. The experimental data of the research, were obtained in the specific testing laboratory from Transilvania University of Brasov.
