He has made significant contributions to the field of casting technology, particularly with his innovative approach to countergravity casting. His work has led to advancements that enhance the efficiency and effectiveness of the casting process.
Latest Patents
Carter holds a patent for a method titled "Countergravity casting using particulate supported thin walled." This invention involves an expendable pattern made from a meltable material that expands upon heating, such as a wax pattern. The pattern is invested with particulate mold material to create a thin, layered shell with a wall thickness not exceeding about 0.12 inch. This design unexpectedly reduces damage and distortion to the shell during the removal process, which is achieved through steam autoclaving. After firing, the thin gas-permeable shell mold is surrounded by a refractory particulate support media within a vacuum housing. The vacuum housing is evacuated to clear the mold cavity defined by the thin shell, while pressure is applied to the support media to compress it around the thin shell. This process supports the shell against casting stresses when molten metal is countergravity cast into the evacuated mold cavity. Carter's innovative approach has resulted in 1 patent.
