Hose, Tubing & Fluid Conveyance Products calculator
Coil/Spool Capacity Calculator
Calculate how many good hose assemblies or cut-to-length pieces you can realistically get from a coil or spool. Enter assemblies per pass, usable passes, equipment uptime, and first-pass yield.
What this calculator does
- Estimate good hose assemblies or cut pieces producible from a coil or spool, accounting for equipment uptime and first-pass yield.
- Use it when planning production from a specific coil or spool to confirm whether available material covers the order.
- Estimates good assemblies or cut pieces from a coil or spool after accounting for uptime and first-pass yield.
Formula used
- Gross coil capacity = assemblies per pass x usable passes
- Good coil capacity = gross capacity x equipment uptime x first-pass yield
Inputs explained
- Assemblies per coil or spool pass: Accepted assemblies or cut pieces completed each coil pass or setup cycle.
- Usable coil or spool passes: Number of usable passes after startup, setup, and end-of-coil losses.
- Equipment uptime: Actual uptime for the cut and crimp equipment from recent production records.
- First-pass assembly yield: Percent of assemblies passing all inspection and test criteria on the first attempt.
How to use the result
- Use it when checking whether material on hand covers the scheduled production run.
- It does not account for fitting count, crimp tooling change, or material specification mismatches that reduce usable output.
Common questions
- What is the Coil/Spool Capacity calculator for? It estimates how many good hose assemblies or cut pieces can be produced from a coil or spool after accounting for uptime and yield.
- What numbers do I need before using it? You need assemblies per pass, usable passes, equipment uptime, and first-pass yield from production records.
- How should I use the result? Use the result to confirm whether material on hand can cover the order, or to determine how many coils to order.
- When is the result only an estimate? It is an estimate when end-of-coil losses, setup waste, or hose type yield differences are not separately tracked.
