Epsilon Rolling Ingot Casting Technology for Aerospace Alloy Casting

The Wagstaff® Epsilon™ Ingot Casting System for Aerospace Alloys is an advanced, specialized technology designed specifically to cast strong alloys for aerospace, military, and commercial applications. The system consists of a mold table, molds, starting head base, and starting heads engineered to produce aerospace alloys of the highest quality and in the most efficient manner.

The technology is designed to keep curl under control at cast start while minimizing shrinkage stress in the newly solidified, strong-alloy ingot.  A specialized, steel, double-curvature starting head is used, and in some configurations, a Wagstaff designed contact wiper system is also employed. 

Each Aerospace Alloy Epsilon™ mold incorporates the Wagstaff® SplitJet™ Enhanced Cooling Technology. This provides a unique water signature and independent control of the primary and secondary water jets for optimizing both the start and run portions of the cast. It also produces the correct cooling rate in steady state while the unique mold geometry minimizes solidification stress, resulting in ingots of superior metallurgical properties.

Included with this and every Wagstaff casting system are the expert techniques and next-generation know-how to successfully and efficiently cast the alloys tailored to suit your goals.

Wagstaff Aerospace Ingot Casting Features and Benefits

  • Most advanced aerospace direct-chill casting research facility in the world

  • Components designed specific to advanced alloy compositions

  • The Epsilon™ mold's robust construction begins with a single precision-machined piece of aluminum.

  • Machined water baffle provides superior water distribution and flow uniformity.

  • Epsilon technology can operate with floats/spouts, steady eddies or automated mold metal level control

  • Can be adapted to any mold table

  • Easy inspection and cleaning of mold cooling water passages.

  • Curl reduction reduces bleedouts at cast start, creating safer start conditions and allowing operation with full automation control. No peripheral curl reduction technologies required, such as pulse water or CO2 injection
