Vacuum Bagging Cost at 110% bagging scope applied to the part: a worked example

Push bagging scope applied to the part up to 110% and the picture changes. This example computes every intermediate figure at that operating point. costing vacuum bag consumables for a composite job

The inputs for this scenario

  • Vacuum bag and consumable coverage area: 620 sq ft (unchanged)
  • Bagging consumables cost per square foot: 2.45 $ / sq ft (unchanged)
  • Bagging scope applied to the part: 110 % (raised for this scenario; the documented default is 100)
  • Fixed vacuum test, fittings and connectors cost: 180 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable vacuum bagging cost = vacuum bag consumable area × bagging consumable cost × bagging scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,851 $ for total vacuum bagging cost, the number this scenario is built around.
  • At this operating point the engine returns 2.99 $ / piece for vacuum bagging cost per part or job.
  • At this operating point the engine returns 1,671 $ for variable vacuum bagging cost.
  • At this operating point the engine returns 180 $ for fixed vacuum test and fitting cost.

How this compares with the baseline

  • Against the tool's baseline example, where bagging scope applied to the part sits at 100% and the headline result is 1,699 $, this scenario comes in 8.94% above the baseline at 1,851 $.
  • It multiplies consumable area by cost per square foot and the bagging scope, then adds fixed vacuum test and fitting cost for a total bagging cost. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • total vacuum bagging cost: 1,851 $ (headline result)
  • vacuum bagging cost per part or job: 2.99 $ / piece
  • variable vacuum bagging cost: 1,671 $
  • fixed vacuum test and fitting cost: 180 $
