For high performance alloys like 718, 625, GTD222, and Rene77.
A vacuum casting is used when part detail and control of exposure to oxygen is critical. MetalTek can cast vacuum parts in sizes up to 18" x 42" (455 mm x 1,070 mm) and pour weights up to 800 lbs. (364 kg).
The vacuum casting process at Wisconsin Centrifugal is performed using a centrifugal process. In addition to the advantages of casting in vacuum, the inherent high metal integrity delivered by centrifugal casting is realized. This includes:
Absence of porosity
