Abstract Scope High-pressure die casting is used to produce lightweight aluminum structural parts with high specific strength. However, a common problem in these parts is entrapped gas which decreases the mechanical properties of the castings. The use of vacuum in the die casting process can reduce the amount of gas porosity. In this study, three vacuum levels were compared in process simulations and high-pressure die-cast samples of two aluminum alloys. The porosity in the die-cast samples was characterized using metallography, density measurements and CT scanning. The decrease in entrapped air and gas porosity was in agreement with the computer simulations. The mechanical properties of the samples were also tested and showed an improvement with increasing vacuum level
