UV Curing worked example

UV Batch Cure Fixture Capacity at 92% uv cell uptime: a worked example

This scenario runs the uv batch cure fixture capacity calculation on the strong side: 92% uv cell uptime, with every other input held at its documented default. Use it when sizing a new UV batch fixture (lab bench cure, spot-cure carousel, manual fixture) instead of a continuous belt - the math is different.

The inputs for this scenario

  • Parts loaded per cure fixture: 8 parts / cycle (unchanged)
  • Completed cure cycles per hour: 20 cycles / hr (unchanged)
  • UV cell uptime: 92 % (raised for this scenario; the documented default is 80)
  • First-pass cure yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross capacity = parts per fixture × cycles per hour) to the inputs above produces each figure below.
  • At this operating point the engine returns 143 good parts / hr (batch) for net good parts / hr, the number this scenario is built around.
  • At this operating point the engine returns 160 parts / hr for gross fixture capacity / hr.
  • At this operating point the engine returns 12.8 parts / hr for loss to cell uptime.
  • At this operating point the engine returns 4.42 parts / hr for loss to cure rejects.

How this compares with the baseline

  • Against the tool's baseline example, where uv cell uptime sits at 80% and the headline result is 124 good parts / hr (batch), this scenario comes in 15% above the baseline at 143 good parts / hr (batch).
  • Use it when planning batch UV cure throughput, sizing how many fixtures or cells a job needs, or reconciling a quoted rate against measured output. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Net good parts / hr: 143 good parts / hr (batch) (headline result)
  • Gross fixture capacity / hr: 160 parts / hr
  • Loss to cell uptime: 12.8 parts / hr
  • Loss to cure rejects: 4.42 parts / hr
