Aluminium is one of the fundamental materials used in many sectors, such as, automotive, defence, aviation, etc. Generally, aluminium parts are formed by using die-casting methods in manufacturing industry. Machines, which are used, for die-casting process have many parameters that affect the molded parts’ mechanical properties. In this study, the effect of casting parameters on the mechanical properties of used material was investigated. A test part that is manufactured currently on a die-casting machine in a sector was found out to do experimental works. An aluminum alloy, named Al𝑆𝑖12𝐶𝑢 (EN AC 47000), that is used widely in die-casting techniques was preferred. Three parameters, such as, metal injection velocity (m/s), time of the die opening (s) and molten metal temperature (°C), were selected. In addition, 27 test parts that were determined by the full factorial experimental design method were manufactured for the molding parameters. Moreover, some mechanical tests, hardness and tensile, were performed on the parts. The test data were analysed with the full factorial and ANOVA statistical methods. As a results of the analysis, the highest hardness value was obtained as 85 HB when the molten metal temperature was 750 °C, the injection velocity was 1,3 m/s and the mold opening time was 10 s. The maximum value of the tensile strength was gotten as 264 MPa in the parameters that are the molten metal temperature 725 °C, injection velocity 4 m/s and the mold opening time was 12 s.
