Sheet Metal Stamping & Press Lines worked example

Progressive Die Output at 99% feed efficiency: a worked example

This scenario runs the progressive die output calculation on the strong side: 99% feed efficiency, with every other input held at its documented default. Use it when progressive die output in sheet metal stamping and press lines is being committed and you need a throughput number you can defend.

The inputs for this scenario

  • Good parts off the progressive die: 1,200 units (unchanged)
  • Die run time: 8 hr (unchanged)
  • Feed efficiency (uptime): 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Raw progressive die output = completed output รท runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 149 units / hr for effective throughput, the number this scenario is built around.
  • At this operating point the engine returns 150 units / hr for raw throughput.
  • At this operating point the engine returns 99 % for efficiency.
  • At this operating point the engine returns 8 hr for runtime.

How this compares with the baseline

  • Against the tool's baseline example, where feed efficiency sits at 90% and the headline result is 135 units / hr, this scenario comes in 10% above the baseline at 149 units / hr.
  • Use it when validating a die's rated speed, planning a production run, or checking whether one die can absorb a volume increase. 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

  • Effective throughput: 149 units / hr (headline result)
  • Raw throughput: 150 units / hr
  • Efficiency: 99 %
  • Runtime: 8 hr

Run it with your numbers

  • Every input above is editable in the live Progressive Die Output calculator, which recalculates instantly and can be shared with the inputs intact.
