Cure Oven Capacity at 65% line uptime: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop line uptime to 65%, then walk the calculation through step by step. Estimate good parts per hour through the cure oven from rack capacity, cycles, uptime, and first-pass yield.

The inputs for this scenario

  • Parts loaded per oven cycle: 24 parts / cycle (held at the documented default)
  • Oven cycles completed per hour: 18 cycles / hr (held at the documented default)
  • Line uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Coating 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.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to line uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes cycles per hour is achievable and steady; a mixed part load with different cure schedules or part densities will change effective cycles and skew the estimate.
