Pressure die casting has become the next area of experimentation on virtual models in computer memory. The article presents an attempt to optimize the manufacturing process of an item made of magnesium AZ91D alloy, which was cast using the pressure technology on a machine with a hot pressing chamber. Special attention was paid to the flow velocity in individual parts of the gating system and in the mould cavity, as well as to the air evacuation from the mould cavity. The aim was to achieve a flawless casting, especially in terms of porosity.
