  • Method for manufacturing a pattern for a hollow component
    Publication number: 20070074839
    Abstract: A pattern with internal cores for creating a hollow component is composed of a first pattern half having one or more first self-locating features; a second pattern half having one or more second self-locating features; and one or more cores disposed in contact with the one or more first self-locating features and the one or more second self-locating features. The method for its manufacture includes the steps of creating a first pattern half having one or more first self-locating features; creating a second pattern half having one or more second self-locating features; providing one or more cores; and assembling the pattern by engaging the one or more first self-locating features and the one or more second self-locating features about the one or more cores.

  • Investment casting
    Publication number: 20050045301
    Abstract: A method and apparatus are used to cast a number of elements such as turbine engine blades. The blades have an airfoil and a root for securing the blade to a disk. A number of mold sections each have internal surfaces for forming an associated at least one of the elements. The mold sections are assembled and molten alloy is introduced to the assembled mold sections.
