Latest Patents
Singh's latest patents focus on foam pattern techniques. These techniques provide various methods for creating fugitive foam patterns used in investment casting operations. In certain illustrative embodiments, a fugitive foam pattern is assembled from independently formed portions. A first section is formed in a mold, and once cured, a mating surface of the first section is exposed to the cavity of a second mold where the second section is formed. The second section integrally adheres to the first section, and this process can be repeated as necessary. In alternative embodiments, a channel is created in a foam pattern using a temporary core that is removed without chemical leaching. The core material can comprise water-soluble materials, acid-soluble materials, low-melting point materials, or a combination thereof. Additionally, a pattern may be created by inserting foam around a core that remains with the foam pattern.
Another method of creating a foam pattern involves mixing a polyol component and an isocyanate component to form a liquid mixture. This method includes placing a temporary core with a shape corresponding to a desired internal feature in a cavity of a mold and inserting the mixture into the cavity so that it surrounds a portion of the temporary core. Supporting pins made of foam can be used to support the core in the mold cavity, becoming an integral part of the pattern material and simplifying subsequent processing. After a predetermined time sufficient for a reaction from the mixture, a foam pattern structure is formed, enclosing a portion of the temporary core, which is then removed independent of chemical leaching.
