Extrusion Throughput at 65% line uptime: a worked example in specialty films, membranes & barrier materials

Suppose 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 extrusion throughput for specialty films, membranes and barrier materials using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Film Output per Extrusion Cycle: 4 units / cycle (held at the documented default)
  • Available Extrusion Cycles: 480 cycles (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 extrusion throughput capacity = extrusion throughput output per cycle × available extrusion throughput cycles.
  • Good extrusion throughput capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross extrusion throughput capacity works out to 1,920 units at these inputs.
  • Extrusion throughput downtime loss works out to 672 units at these inputs.
  • Extrusion 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 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.
  • It computes good throughput as gross capacity, output per cycle times available cycles, derated by line uptime and first-pass yield, and breaks out the downtime and yield losses. 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.

Results at a glance

  • Good extrusion throughput capacity: 1,211 units (headline result)
