UV Curing worked example
UV Cure System Throughput at 98% line uptime: a worked example
Push line uptime up to 98% and the picture changes. This example computes every intermediate figure at that operating point. Use it when sizing capacity for a new program, deciding whether a UV cell is the bottleneck, or answering 'how many can we ship per shift'.
The inputs for this scenario
- Parts per belt foot: 2 parts / ft (unchanged)
- Belt speed: 30 ft / min (unchanged)
- Line uptime: 98 % (raised for this scenario; the documented default is 85)
- Cure-related yield: 97 % (unchanged)
Working through the calculation
- Applying the documented formula (Gross throughput (parts/hr) = parts per belt foot × belt speed × 60) to the inputs above produces each figure below.
- At this operating point the engine returns 57.04 good parts / hr for net good cured parts / hr, the number this scenario is built around.
- At this operating point the engine returns 60 parts / hr for gross throughput (nameplate).
- At this operating point the engine returns 1.2 parts / hr for hours lost to uptime.
- At this operating point the engine returns 1.76 parts / hr for loss to cure-related rejects.
How this compares with the baseline
- Against the tool's baseline example, where line uptime sits at 85% and the headline result is 49.47 good parts / hr, this scenario comes in 15.29% above the baseline at 57.04 good parts / hr.
- It computes net good cured parts per hour by multiplying belt loading by belt speed to get gross throughput, then derating that by line uptime and cure-related yield. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
Results at a glance
