  • Article casting method
    Patent number: 7082984
    Abstract: The present invention is a method for casting a part having a complex shape or having a complex shape thereon. The method includes providing a pattern and securing at least one core to the pattern. A conformable material is located about the pattern and the core to create a complementary shape to the pattern and core in the conformable material. The pattern is removed and the core is left behind in the conformable material. The core leaves space, or an empty form, for a negative draw that cannot be formed in known casting methods. A mold is located adjacent the shaped, conformable material. A hardenable material is located between the mold and the shaped, conformable material and into the core. The hardenable material is allowed to harden and then it is removed. A cast part having a complex shape, or having a complex shape integrally formed with the part, results.
