Shakeout Capacity at 63% shakeout equipment availability: a worked example

Suppose shakeout equipment availability falls to 63%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate good shakeout output capacity for molds, castings, or poured molds per shift.

The inputs for this scenario

  • Castings or molds per shakeout cycle: 6 units / cycle (held at the documented default)
  • Available shakeout cycles: 70 cycles (held at the documented default)
  • Shakeout equipment availability: 63 % (the input this scenario stresses; the baseline uses 88)
  • Accepted shakeout yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross shakeout capacity = castings or molds per shakeout cycle × available shakeout cycles.
  • Good shakeout capacity works out to 257 units at these inputs, and this is the headline figure for the scenario.
  • Gross shakeout capacity works out to 420 units at these inputs.
  • Shakeout Capacity downtime loss works out to 155 units at these inputs.
  • Shakeout Capacity reject or rework loss works out to 7.94 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where shakeout equipment availability sits at 88% and the headline result is 359 units, this scenario comes in 28.41% below the baseline at 257 units.
  • It computes good (sellable) shakeout output by multiplying gross capacity by equipment availability and accepted 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.

Results at a glance

  • Good shakeout capacity: 257 units (headline result)
  • Gross shakeout capacity: 420 units
  • Shakeout Capacity downtime loss: 155 units
  • Shakeout Capacity reject or rework loss: 7.94 units
