Coil/Spool Capacity at 65% crimper and cut-line uptime: a worked example

This worked example runs the coil/spool capacity numbers for a tougher week than the baseline: 65% crimper and cut-line uptime instead of the typical 90%. Estimate good hose assemblies or cut pieces producible from a coil or spool, accounting for equipment uptime and first-pass yield.

The inputs for this scenario

  • Assemblies cut per coil or spool pass: 50 assemblies / pass (held at the documented default)
  • Usable passes per coil or spool: 18 passes (held at the documented default)
  • Crimper and cut-line uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • First-pass assembly yield: 96 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross coil capacity = assemblies per pass x usable passes.
  • Good assemblies from coil or spool works out to 562 assemblies at these inputs, and this is the headline figure for the scenario.
  • Gross coil or spool capacity works out to 900 assemblies at these inputs.
  • Equipment downtime loss works out to 315 assemblies at these inputs.
  • Quality yield loss works out to 23.4 assemblies at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where crimper and cut-line uptime sits at 90% and the headline result is 778 assemblies, this scenario comes in 27.78% below the baseline at 562 assemblies.
  • Use it when sizing bulk hose purchases against an order release or converting available spools into a committed assembly schedule. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Good assemblies from coil or spool: 562 assemblies (headline result)
  • Gross coil or spool capacity: 900 assemblies
  • Equipment downtime loss: 315 assemblies
  • Quality yield loss: 23.4 assemblies

Run it with your numbers
