Cell A20 Plenum


Magna Machine was contracted to build a portion of the new test cell for GE Aviation. The 2-walled pressure vessel is designed to mimic the flow of air through the compressor, thus allowing GE to test various components under real life conditions inside the engine. This test system runs at twice the pressure and temperatures as existing test systems.

This program was a multimillion dollar contract which required Magna to manage everything from material procurement through final inspection. It also demonstrated our willingness to work with customers who are concurrently designing and building a component.
The client chose us based on our proximity to GE and our eagerness to work with them while they were still completing the job.
Difficulties Overcome: Material delivery, deep grooves, welding.
Positive Client Feedback: Component work wonderfully.
Special Feature of this Product: Deep grooves, X Ray welded Joints
Finished Product:
  • Programmers
  • Engineering
  • VTL Machinists
  • HBM Machinists
  • Welders
  • Weld Inspectors
