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.

Abstract: A wax tree assembly heating system for heating wax on the surface of a wax component is provided. The system includes an elongated bar of heat conducting material, having a heating surface, and a heating element for heating the heating surface. The heating surface is configured to contact a wax component, such as a wax runner or a gate of a wax pattern, and has a space for retaining molten wax when the heating surface contacts a surface of the wax component. In another embodiment, the wax tree assembly heating system has a plurality of raised heating surfaces that are configured for producing molten wax on a plurality of areas on one or more surfaces of at least one wax component. Additionally, an electrical circuit is provided which includes a heating element and a temperature controller to control the temperature at which wax is melted.

Abstract: A process for the assembly of wax trees in which a wax runner is placed in a flat position and a wax pattern is located adjacent the wax runner. Both the wax runner pattern and the wax runner are heated and then are placed in contact with one another where heated. Then the wax pattern and the wax runner are separated slightly to form a fillet weld between the wax pattern and the wax runner. An apparatus is also provided which, by robotics, brings a multiplicity of wax patterns to a wax runner and which automatically heats both the wax patterns and the wax runner before simultaneously pressing both the wax pattern and the wax runner together. Once a wax tree assembly is completed a new wax runner replaces the wax runner that has been formed into a wax tree and additional wax runners are affixed in the same manner.
