The method comprises melting and filling a hardenable aluminum alloy into a die casting mold (4), and cooling the melted aluminum alloy (1) by the mold made of a material having a thermal conductivity causing the melted aluminum alloy to be cooled at a cooling rate >= 5x 10 2> K/s, where the melted aluminum alloy is introduced into a filling chamber (2) and is displaced at a minimal displacement speed within the filling chamber, prior to the filling step. The molten alloy is displaced at a low speed of less than 0.5 m/s in a filling chamber in the first phase.

The molten alloy is displaced at a low speed of less than 0.5 m/s in a filling chamber in the first phase. The molten alloy is moved at high speed of 1-3 m/s from the filling chamber into the die-casting mold in a second phase. The molten alloy is set after complete filling of the die under pressure. |
