| titleOfInvention | Method of using thermally reversible metal to form ceramic molds |
| abstract | A method for forming a ceramic mold comprises the step of placing a pattern having critical pattern surfaces in a flask having an open end. The critical pattern surfaces face upward toward the open end. Successive steps include adding a heat reversible liquid metal to the flask to cover the critical pattern surfaces, and cooling the liquid metal to form a solid metal mold. The metal mold has critical metal mold surfaces inverse to the critical pattern surfaces. Further steps include removing the pattern from the metal mold, casting a ceramic mold around the metal mold, and liquifying the metal mold to remove it from the ceramic mold. The ceramic mold has critical ceramic surfaces inverse to the critical metal mold surfaces, thereby accurately replicating the critical pattern surfaces. |
