A new method for vacuum casting titanium is described. The device allows decontamination of the mold before placing it into the casting machine. After wax elimination, the mold is placed into the device and sealed with a thin film of titanium. The air is evacuated from the mold, and it is flushed with helium. The process is repeated, and the casting is made when convenient.
