Composites, Fiberglass & Advanced Materials calculator
Vacuum Bagging Cost Calculator
Use this calculator to cost bag film, sealant tape, peel ply, breather, release film, flow media, fittings, and leak-check consumables for a bagged part or tool.
What this calculator does
- Estimate vacuum bag consumable cost for composite layup, infusion, or cure operations.
- costing vacuum bag consumables for a composite job
- The result estimates total vacuum bagging material and setup cost.
Formula used
- Variable vacuum bagging cost = vacuum bag consumable area × bagging consumable cost × bagging scope included
- Total vacuum bagging cost = variable vacuum bagging cost + fixed vacuum test and fitting cost
Inputs explained
- vacuum bag consumable area: Use bag film area plus peel ply, breather, release film, flow media, and overlap allowances as applicable.
- bagging consumable cost: Use issued material cost for film, tape, peel ply, breather, release film, flow media, ports, and fittings.
- bagging scope included: Use 100% for the complete bag stack or less for one consumable family or shared tool setup.
- fixed vacuum test and fitting cost: Include reusable fittings, vacuum ports, leak-check supplies, special tapes, or job-specific setup.
How to use the result
- Use it for quote allowances, consumable staging, bagging method comparison, or cost reduction work.
- Treat the result as a planning estimate until it is checked against the approved laminate schedule, material datasheets, ply books, resin batch records, tool condition, cure logs, inspection results, customer specification, and actual shop observations for the same part family and process.
Common questions
