Latest Patents

Fujii's latest patent involves a production method of castings and a gas-permeable casting mold. This innovative method utilizes a gas-permeable casting mold that comprises a cavity made up of a production cavity and a flow path. The flow path includes a sprue through which a gravity-poured melt flows downward, and a runner that connects the production cavity to the sprue. The process involves gravity-pouring a metal melt in a volume smaller than that of the entire cavity but larger than that of the production cavity into the gas-permeable casting mold. By supplying gas through the sprue, the metal melt is pushed upward in the production cavity, ensuring that it fills completely. This method establishes a hypothetical equilibrium state where the volume of the metal melt poured equals the volume of a hypothetical liquid, optimizing the casting process.
