Title: Innovations by William F. Dunfee
Introduction
William F. Dunfee is a notable inventor based in Denver, NC (US). He has made significant contributions to the field of molding apparatuses, particularly in the design of gaskets used in filter elements for internal combustion engines. With a total of 2 patents, his work has been instrumental in improving the efficiency and reliability of these components.
Latest Patents
Dunfee's latest patents include a molding apparatus designed to prevent the formation of flash on gaskets. This innovative method utilizes a pair of mold components that abut along a mold line, defining a cavity for forming the gasket. As the expandable material fills the cavity, a portion adjacent to the mold line is received in an annular groove, effectively preventing flash formation. Additionally, one of the mold components features an upwardly sloping ramp surface, allowing air and gas to move along it as the material expands, thus avoiding defects caused by trapped air bubbles.
Another significant patent by Dunfee is a molding process for forming a sealing gasket on filter media. This process mirrors the principles of his first patent, ensuring that the gasket is formed without flash and that air is efficiently expelled during the molding process. These innovations reflect Dunfee's commitment to enhancing the performance of filter elements in various applications.
