Benefits of technology
The present invention provides a method for producing cast components in an inexpensive and efficient way. The method involves using a die casting mold made of a material with high thermal conductivity to cool the cast components quickly. This allows for the formation of an oversaturated mixed crystal that does not require additional thermal treatment. The method requires minimal technological expenditure and is faster than existing methods. The invention also ensures minimal air inclusion or air entrapment by allowing the melt of the alloy to move at a minimal speed and preventing waves or bubbles from forming. The melt is filled or pressed into the die casting mold at high speed to ensure complete filling of the mold. In an embodiment, post pressure is used to compensate for the reduced density of the alloy melt and prevent bubbles or cavities in the cast component.

Embodiment Construction
[0019]The method according to the invention which will be explained in more detail in the following enables producing an aluminum alloy that can be hardened without requiring the step of solution annealing and preferably without requiring quenching. The alloy can therefore be produced in a simple and inexpensive way requiring only little time. The method is characterized by a simple process control.
[0020]The method is suitable for hardenable aluminum alloys that in addition to aluminum contain at least two other components. For example, the method is suitable for Al—Mn—Si, Al—Zn—Mg, Al—Si—Cu or Al—Si—Mg alloys. A particularly advantageous aluminum alloy is the alloy 6101. The aluminum alloys have a high electrical conductivity that is higher than approximately 28 MS / m.
[0021]With the aid of FIGS. 2 through 4, the method will be explained in more detail. The melted alloy 1 is contained in a fill chamber 2. The melted alloy is displaced in this fill chamber 2 by means of piston 3 in th...

Abstract
In a method for producing cast components for electrical applications, a hardenable aluminum alloy is melted and filled into a die casting mold. The melted aluminum alloy is cooled by the die casting mold that is comprised of a material that has a thermal conductivity causing the melted aluminium alloy to be cooled at a cooling rate of approximately ≧5×102 K / s. Prior to filling, the melted aluminum alloy is introduced into a fill chamber and the melted aluminum alloy is displaced at a minimal displacement speed within the fill chamber.
Description
BACKGROUND OF THE INVENTION[0001]The invention relates to a method for producing cast components for electrical applications in which hardenable aluminum alloys are used which are melted and introduced into a die casting mold.[0002]It is known to produce die cast components for electrical applications, for example, for electrical conductors, high-voltage switches, rotors or stators in electrical motors, and the like. For this purpose, inter alia aluminum alloys are used that can be hardened. Such aluminum alloys are, for example, Al—Cu, Al—Mn—Si, Al—Zn—Mg, Al—Si—Cu, or Al—Si—Mg. The hardenable alloys have an electrical conductivity that is usually greater than approximately 28 MS / m. In order to improve the mechanical properties of the various aluminum alloys, it is known to provide in the microstructure of these alloys so-called Guinier-Preston zones. These are coherent precipitations by means of which the strength of the aluminum alloys can be increased.[0003]With the aid of FIG. 1...
