  • 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.
