N.B.E. Press Cycle
Phase 1

Container is kept open by NBE cylinders acting on container holder shifting cylinders; Max. 0.079"

Start of billet upsetting

N.B.E. Press Cycle
Phase 2

Container remains open allowing air to escape until billet / container friction force is greater than NBE cylinders force

N.B.E. Press Cycle
Phase 3

Billet upsetting completed and container is closed

Extrusion begins
