Recent research in the process of aluminum alloy die castings production, which is nowadays deeply implemented into the rapidly growing
automobile, shipping and aircraft industries, is aimed at increasing the useful qualitative properties of the die casting in order to obtain its
high mechanical properties at acceptable economic cost. Problem of technological factors of high pressure die casting has been a subject of
worldwide research (EU, US, Japan, etc.). The final performance properties of die castings are subjected to a large number of
technological factors. The main technological factors of high pressure die casting are as follows: plunger pressing speed, specific
(increase) pressure, mold temperature as well as alloy temperature. The contribution discusses the impact of the plunger pressing speed
and specific (increase) pressure on the mechanical properties of the casting aluminum alloy.
