Introduction
Ronald James Keller is a notable inventor based in Grand Haven, MI (US). He has made significant contributions to the field of ceramic investment casting, holding a total of four patents. His innovative methods have advanced the efficiency and effectiveness of manufacturing processes in this domain.
Latest Patents
One of his latest patents is a method of making investment casting molds. This method involves forming a ceramic investment shell mold around a fugitive wax pattern. The process includes coating the pattern with ceramic slurry, applying heated ceramic particulate material, and drying the layers to build up the shell mold. This technique allows for the construction of ceramic investment shell molds in less than 10 hours, significantly reducing the incidence of cracking during the building process and subsequent pattern removal.
Another significant patent is related to the method of making a ceramic core for casting industrial gas turbine engine airfoils. This method involves creating a precursor core of smaller dimensions, firing it, and then applying a thin ceramic skin to form a coated core of final dimensions. The firing of the thin ceramic skin minimizes airfoil pitch shrinkage, thereby reducing overall dimensional tolerance variations.
