Extrusion Puller Speed Calculator at 99% puller operating efficiency: a worked example

What does the result look like when puller operating efficiency reaches 99%? The full calculation is worked below with real intermediate numbers. a press operator or process engineer needs to check puller speed for a profile run

The inputs for this scenario

  • Extruded profile length pulled: 2,400 ft (unchanged)
  • Active pull time: 55 min (unchanged)
  • Puller operating efficiency: 99 % (raised for this scenario; the documented default is 92)

Working through the calculation

  • Applying the documented formula (Measured puller speed = extruded profile length pulled รท active pull time) to the inputs above produces each figure below.
  • At this operating point the engine returns 43.2 ft/min for effective puller speed, the number this scenario is built around.
  • At this operating point the engine returns 43.64 ft/min for measured puller speed.
  • At this operating point the engine returns 99 % for puller operating efficiency.
  • At this operating point the engine returns 55 min for active pull time.

How this compares with the baseline

  • Against the tool's baseline example, where puller operating efficiency sits at 92% and the headline result is 40.15 ft/min, this scenario comes in 7.61% above the baseline at 43.2 ft/min.
  • A figure at this level is achievable when puller operating efficiency is genuinely sustained, not just peaked for a shift. It treats speed as an average over the pull; real extrusion ramps speed across the cycle (break-out, steady state, billet end), so the average can hide instantaneous mismatches that cause defects.

Results at a glance

  • Effective puller speed: 43.2 ft/min (headline result)
