Shakeout Capacity at 99% shakeout equipment availability: a worked example

This scenario runs the shakeout capacity calculation on the strong side: 99% shakeout equipment availability, with every other input held at its documented default. Use it when deciding whether shakeout, knockout, cooling, and mold handling can keep up with the molding and pouring schedule.

The inputs for this scenario

  • Castings or molds per shakeout cycle: 6 units / cycle (unchanged)
  • Available shakeout cycles: 70 cycles (unchanged)
  • Shakeout equipment availability: 99 % (raised for this scenario; the documented default is 88)
  • Accepted shakeout yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross shakeout capacity = castings or molds per shakeout cycle × available shakeout cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 403 units for good shakeout capacity, the number this scenario is built around.
  • At this operating point the engine returns 420 units for gross shakeout capacity.
  • At this operating point the engine returns 4.2 units for shakeout capacity downtime loss.
  • At this operating point the engine returns 12.47 units for shakeout capacity reject or rework loss.

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 12.5% above the baseline at 403 units.
  • Use it when checking whether the shakeout station can absorb the mold-per-shift rate coming off the pouring line, or when planning a capacity change. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good shakeout capacity: 403 units (headline result)
  • Gross shakeout capacity: 420 units
  • Shakeout Capacity downtime loss: 4.2 units
  • Shakeout Capacity reject or rework loss: 12.47 units
