Abstract
A process for creating a lost wax tree, including the steps of assembling a wax tree having a wax pattern and a wax runner, using automated equipment to flex either the wax tree or the wax pattern to bring disconnected sections into proximity, heating at least one of the disconnected sections, contacting the disconnected sections and then moving the sections slightly away from one another. A process for casting a part including the steps of creating a lost wax tree and where the wax tree is later covered with a mold material and the wax tree is removed to create a mold, the mold is then used to cast a part similar to the wax pattern. A lost wax tree having a wax tree with a wax pattern and a wax runner, automated equipment for flexing, a heating element, and automated equipment for manipulating disconnected sections.
