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.
