Casting device and associated method for investment casting with improved mechanical properties

摘要

The invention describes a method of casting a metal comprising the following steps: fabricating a pattern from wax or plastic having the geometry to generate a desired object, fabricating an investment mold from the wax, placing the mold in an open pressure vessel, filling the investment mold with a molten metal alloy, immediately thereafter closing and pressure sealing the pressure vessel, pressurizing the sealed pressure vessel with an inert gas for a predetermined measured time, depressurizing the sealed pressure vessel, opening the pressure vessel and removing the metal filled investment mold, and extracting the desired object from the investment mold.

1. A method of casting a metal alloy comprising the following steps:
fabricating a pattern from wax or plastic having the appropriate geometry to generate a desired object to be cast; placing the investment mold in an open pressure vessel; filling the investment mold with a molten metal alloy; immediately thereafter closing and pressure sealing the pressure vessel; pressurizing the sealed pressure vessel with an inert gas for a predetermined measured time; said predetermined measured time sufficient for the molten metal to cool and solidify; depressurizing the sealed pressure vessel; opening the pressure vessel and removing the metal filled investment mold; and extracting the desired object from the investment mold.
