Sizing Press Capacity at 65% sizing press uptime: a worked example

Suppose sizing press 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. Sizing (or coining) press capacity is the number of good, dimensionally corrected sintered parts a repress operation can deliver in a given window.

The inputs for this scenario

  • Parts sized per press stroke: 4 units / cycle (held at the documented default)
  • Available press strokes in the window: 480 cycles (held at the documented default)
  • Sizing press uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Post-size yield: 97 % (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where sizing press 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 multiplies parts per stroke by available strokes for gross capacity, then applies uptime and yield to give good output plus the parts lost to downtime and scrap. 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.
