With a total of five patents to his name, Sargent’s work has had a profound impact on enhancing the efficiency and effectiveness of foundry processes.
Latest Patents
Among his latest patents, one of the standout innovations is the development of a foundry sand with an oxidation promoter. This innovative sand mold is designed for shaping molten metal cast into the mold. It features a thermally oxidizable polymer that is incorporated within the sand grains, along with a catalyst coating that promotes the thermal oxidation and breakdown of the polymer during sand removal and reclamation. This unique catalyst coating adheres exceptionally well to the sand grains, allowing them to withstand multiple casting and reclamation cycles without needing to replenish the catalyst.
Another notable patent addresses the issue of removing lost foam pattern coating residue from aluminum castings. This process involves coating a fugitive pattern with a refractory coating that includes a thermally stable, water-insoluble, acid-gasifiable compound such as calcium carbonate. The casting, covered with this coating, is then treated with an acid to dissociate and gasify the compound, effectively rupturing the coating. The method is designed to neutralize any thermal degradation products from the pattern to enhance the coating's wetting properties.
