  • Method and apparatus for estimating dimensional uniformity of cast object
    Patent number: 11607723
    Abstract: A method and apparatus for providing an estimate of uniformity of wall thickness of a centrifugally cast object, such as a pipe cast from molten iron, substantially immediately after the casting process is complete. The volume of molten metal entering the mold over time is determined and correlated with casting machine position and velocity data to estimate wall thickness along the length of the pipe. Process defects can then be identified promptly and corrective action taken.
    Type: Grant
    Filed: May 5, 2022
    Date of Patent: March 21, 2023
    Assignee: United States Pipe and Foundry Company, LLC
    Inventors: Kenneth J Watts, Stephanie R Holtz
