Pultrusion & Continuous Composite Profiles worked example

Scrap Length Cost at 92% unrecoverable-material fraction: a worked example

This scenario runs the scrap length cost calculation on the strong side: 92% unrecoverable-material fraction, with every other input held at its documented default. Use it when scrap length cost in pultrusion and continuous composite profiles is being put through a pultrusion and continuous composite profiles weighted-cost review.

The inputs for this scenario

  • Scrap profile length: 100 ft (unchanged)
  • Loaded cost per scrap foot: 45 $ / ft (unchanged)
  • Unrecoverable-material fraction: 92 % (raised for this scenario; the documented default is 80)
  • Fixed scrap handling cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Scrap Length Cost cost = quantity × rate × capture factor + fixed cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 ft for weighted cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for per piece value.
  • At this operating point the engine returns 4,140 $ for captured value.
  • At this operating point the engine returns 250 $ for fixed adjustment.

How this compares with the baseline

  • Against the tool's baseline example, where unrecoverable-material fraction sits at 80% and the headline result is 3,850 ft, this scenario comes in 14.03% above the baseline at 4,390 ft.
  • Use it when tallying the cost of a die change, a bad run, or a chronic startup-scrap problem, and when building a scrap-reduction business case. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Weighted cost: 4,390 ft (headline result)
  • Per piece value: 43.9 $ / piece
  • Captured value: 4,140 $
  • Fixed adjustment: 250 $
