  • Investment casting process
    Patent number: 5494096
    Abstract: An investment casting process utilizes a temporary mold which is formed by pouring a liquid over a positive pattern, and cooling the liquid until it solidifies. The positive pattern is removed, and a temporary pattern is formed by pouring another liquid into the cavity of the temporary mold, and cooling the second liquid until it solidifies. The temporary mold may then be melted or dissolved to leave a temporary pattern, which may be coated with a ceramic slurry to form a ceramic shell. The temporary pattern may then be melted or dissolved in order to remove the temporary pattern from the ceramic shell. The ceramic shell may be filled with molten metal which is allowed to solidify to form the final cast piece.
