Vacuum Casting
High performance alloys like 718, 625, GTD222, and Rene77 may require the use of vacuum during casting. Vacuum is used when part detail and control of exposure to oxygen is critical. MetalTek can centrifugally cast parts in vacuum in sizes up to 18" x 42" (455 mm x 1,070 mm) and pour weights up to 900 lbs. (410 kg).
Vacuum casting 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, including directional solidification, absence of porosity, and net shaping. Vacuum centrifugal casting provides products with very high reliability, often used in aerospace and military applications.
