Coating Line Throughput at 65% line uptime: a worked example
This worked example runs the coating line throughput numbers for a tougher week than the baseline: 65% line uptime instead of the typical 90%. Estimate good parts per hour through wash, dry-off, booth, and cure using rack count, cycles, uptime, and yield.
The inputs for this scenario
- Parts per rack or carrier: 24 parts / cycle (held at the documented default)
- Line cycles per hour: 18 cycles / hr (held at the documented default)
- Line uptime: 65 % (the input this scenario stresses; the baseline uses 90)
- First-pass yield: 97 % (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Gross capacity = positions/rate × cycles.
- Good output capacity works out to 272 parts / hr at these inputs, and this is the headline figure for the scenario.
- Gross capacity works out to 432 parts / hr at these inputs.
- Uptime loss works out to 151 parts / hr at these inputs.
- Yield loss works out to 8.42 parts / hr at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where line uptime sits at 90% and the headline result is 377 parts / hr, this scenario comes in 27.78% below the baseline at 272 parts / hr.
- Use it when quoting a finishing job, balancing a line against upstream feed, or diagnosing why actual output trails the nameplate hanger count. 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.
