Core with thermal conducting conduit therein and related system and method

Abstract:

A core for forming a casting article including a sacrificial material about the core is disclosed. The casting article is used for forming a mold for investment casting a component. The core may include a body having an external shape to form at least a section of an internal structure of the component during the investment casting; and a closed loop, core thermal conducting conduit inside a portion of the body. The closed loop, core thermal conducting conduit defines a path for a temperature controlled thermal fluid to pass through the portion of the body to control a temperature of the portion during forming of the casting article. A system may include the core and a thermal fluid controller for controlling the temperature of the thermal fluid. A related method is also disclosed.
