Fin Press Output at 99% fin press efficiency: a worked example

What does the result look like when fin press efficiency reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when a fin press, louver fin die, corrugated fin line, or fin stamping cell must feed tube insertion, core build, or assembly demand.

The inputs for this scenario

  • Accepted fins produced: 1,200 fins (unchanged)
  • Press runtime: 8 hr (unchanged)
  • Fin press efficiency: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where fin press efficiency sits at 90% and the headline result is 135 fins / hr, this scenario comes in 10% above the baseline at 149 fins / hr.
  • A figure at this level is achievable when fin press efficiency is genuinely sustained, not just peaked for a shift. It uses a single efficiency factor and a runtime you supply; it will not capture intermittent slowdowns or a die wearing through a long run unless you re-measure.

Results at a glance

  • Effective fin press output: 149 fins / hr (headline result)
  • Raw fin press output: 150 fins / hr
  • Fin press efficiency: 99 %
  • Press runtime: 8 hr
