Mask Line Throughput at 65% mask line uptime: a worked example

Suppose mask line uptime falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate mask line throughput for ppe and infection control products using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Masks produced per machine cycle: 4 units / cycle (held at the documented default)
  • Available production cycles per shift: 480 cycles (held at the documented default)
  • Mask line uptime (OEE availability): 65 % (the input this scenario stresses; the baseline uses 90)
  • First-pass yield after weld and ear-loop inspection: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross mask line throughput capacity = mask line throughput output per cycle × available mask line throughput cycles.
  • Good mask line throughput capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross mask line throughput capacity works out to 1,920 units at these inputs.
  • Mask line throughput downtime loss works out to 672 units at these inputs.
  • Mask line throughput yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where mask line uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • Computes good (saleable) mask capacity per shift by multiplying units per cycle by available cycles, then discounting for line uptime and first-pass yield. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
