Plastics Extrusion - Pipe, Film & Profile worked example
Haul-Off Speed at 99% haul-off efficiency: a worked example
This scenario runs the haul-off speed calculation on the strong side: 99% haul-off efficiency, with every other input held at its documented default. Use it when setting puller speed for pipe, sheet, film, or profile extrusion and checking it against output and gauge targets.
The inputs for this scenario
- Good product length pulled: 1,500 ft (unchanged)
- Puller run time: 60 min (unchanged)
- Haul-off efficiency: 99 % (raised for this scenario; the documented default is 94)
Working through the calculation
- Applying the documented formula (Raw haul-off speed = good pulled length รท elapsed puller time) to the inputs above produces each figure below.
- At this operating point the engine returns 24.75 ft / min for practical haul-off speed, the number this scenario is built around.
- At this operating point the engine returns 25 ft / min for calculated haul-off speed.
- At this operating point the engine returns 99 % for haul-off efficiency.
- At this operating point the engine returns 60 min for elapsed puller time.
How this compares with the baseline
- Against the tool's baseline example, where haul-off efficiency sits at 94% and the headline result is 23.5 ft / min, this scenario comes in 5.32% above the baseline at 24.75 ft / min.
- Use it when quoting production time, validating a line's real output, or setting a realistic haul-off target that accounts for downtime and scrap. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
