  • Sealed impeller for producing metal foam and system and method therefor
    Patent number: 7481964
    Abstract: A system for producing a metal foam comprises a bath containing a molten metal, a rotating shaft or impeller extending through the base of the bath into, and submerged in the molten metal, and a gas discharge nozzle provided on the submerged end of the shaft. The opposite end of the shaft is connected to a gas supply line and the shaft is rotated with a motor. A seal is provided at the opening in the base of the bath for preventing leakage of the molten metal there-through.

  • Method and apparatus for low pressure aluminum foam casting
    Patent number: 6932146
    Abstract: A method for casting an article composed of a foamed metal includes positioning a die with a die cavity above a bath of a molten metal and pressurizing the bath to cause the molten metal to fill the die cavity. A gas is then bubbled through the molten metal to form a foam. The foam is formed in the die cavity. Once the foam in the die cavity is solidified, the pressure in the bath is released and the formed article is removed. An apparatus for the method includes a die positioned above the bath, the die having a die cavity in fluid communication with the bath. The bath is provided with a pressurizing means and a venting means as well as a gas supply port for forming the foam.
