Title: Innovations by Alan J Graham
Introduction
Alan J Graham is a notable inventor based in Whitehall, MI (US). He has made significant contributions to the field of investment casting, holding 2 patents that showcase his innovative approach to improving manufacturing processes.
Latest Patents
One of his latest patents focuses on an investment casting method that utilizes a pattern material with substantially spherical filler particulates. This method is designed to produce investment cast components with enhanced surface quality, reduced finishing costs, and minimized core breakage. The pattern material consists of spherical particles ranging from about 10 microns to about 70 microns in diameter. This innovation effectively reduces the occurrence of random, localized surface depressions and pits, thereby improving the texture and uniformity of the pattern surface. The resulting castings exhibit an improved as-cast surface finish, which significantly reduces or eliminates the need for expensive post-casting surface finishing operations. Additionally, the spherical morphology of the filler particulates lowers the injection pressures required to fill a pattern die cavity, which helps to prevent breakage of ceramic cores used in the manufacture of hollow cast components, such as internally cooled turbine blades and vanes.
