Permanent Mold Casting

New Casting Technology:

Proprietary graphite is machined into molds by high speed CNC mills using CAD/CAM software.  Alloys are vacuum melted and cast in the machined molds.  After the casting is removed from the mold cavity, the mold is reused for the repeat production of the same part.  Superalloys and titanium alloys are produced by this new technology with superior quality.
