UV Curing worked example

UV Cure Line Daily Capacity at 98% line availability and uptime: a worked example

What does the result look like when line availability and uptime reaches 98%? The full calculation is worked below with real intermediate numbers. Use it for shipment planning, S&OP capacity reviews, and answering 'how many can the UV line do per day' for a customer commitment.

The inputs for this scenario

  • Cured parts per hour at speed: 320 parts / hr (unchanged)
  • Scheduled run hours per day: 16 hr / day (unchanged)
  • Line availability / uptime: 98 % (raised for this scenario; the documented default is 85)
  • First-pass cure yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross daily capacity = hourly throughput × shift hours per day) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,867 parts / day for net good parts / day, the number this scenario is built around.
  • At this operating point the engine returns 5,120 parts / day for gross daily capacity.
  • At this operating point the engine returns 102 parts / day for loss to uptime.
  • At this operating point the engine returns 151 parts / day for loss to cure rejects.

How this compares with the baseline

  • Against the tool's baseline example, where line availability and uptime sits at 85% and the headline result is 4,221 parts / day, this scenario comes in 15.29% above the baseline at 4,867 parts / day.
  • A figure at this level is achievable when line availability and uptime is genuinely sustained, not just peaked for a shift. It uses average uptime and yield; it will not capture the variability of a line that alternates between long clean runs and bad days, so plan buffers accordingly.

Results at a glance

  • Net good parts / day: 4,867 parts / day (headline result)
  • Gross daily capacity: 5,120 parts / day
  • Loss to uptime: 102 parts / day
  • Loss to cure rejects: 151 parts / day
