Pouring Line Throughput at 99% pouring efficiency: a worked example

Push pouring efficiency up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when pouring capacity, ladle availability, mold queue, pour crew, or cooling space must support a production schedule.

The inputs for this scenario

  • Molds or castings poured: 140 units (unchanged)
  • Pouring-line runtime: 7.5 hr (unchanged)
  • Pouring efficiency: 99 % (raised for this scenario; the documented default is 88)

Working through the calculation

  • Applying the documented formula (Raw pouring line throughput = molds or castings poured รท pouring-line runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 18.48 units / hr for effective pouring line throughput, the number this scenario is built around.
  • At this operating point the engine returns 18.67 units / hr for raw throughput.
  • At this operating point the engine returns 99 % for pouring efficiency.
  • At this operating point the engine returns 7.5 hr for pouring-line runtime.

How this compares with the baseline

  • Against the tool's baseline example, where pouring efficiency sits at 88% and the headline result is 16.43 units / hr, this scenario comes in 12.5% above the baseline at 18.48 units / hr.
  • It computes effective pouring line throughput by taking the raw rate (molds poured divided by runtime) and discounting it for pouring efficiency. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Effective pouring line throughput: 18.48 units / hr (headline result)
  • Raw throughput: 18.67 units / hr
  • Pouring efficiency: 99 %
  • Pouring-line runtime: 7.5 hr
