Aluminum Extrusion & Profile Manufacturing worked example

Extrusion Puller Speed Calculator at 66% puller operating efficiency: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop puller operating efficiency to 66%, then walk the calculation through step by step. Estimate effective puller speed from extruded length, pull time, and puller efficiency for an aluminum profile run.

The inputs for this scenario

  • Extruded profile length pulled: 2,400 ft (held at the documented default)
  • Active pull time: 55 min (held at the documented default)
  • Puller operating efficiency: 66 % (the input this scenario stresses; the baseline uses 92)

Working through the calculation

  • The calculation starts from the formula this tool documents: Measured puller speed = extruded profile length pulled รท active pull time.
  • Effective puller speed works out to 28.8 ft/min at these inputs, and this is the headline figure for the scenario.
  • Measured puller speed works out to 43.64 ft/min at these inputs.
  • Puller operating efficiency works out to 66 % at these inputs.
  • Active pull time works out to 55 min at these inputs.

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 28.26% below the baseline at 28.8 ft/min.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to puller operating efficiency, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. 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: 28.8 ft/min (headline result)
  • Measured puller speed: 43.64 ft/min
  • Puller operating efficiency: 66 %
  • Active pull time: 55 min
