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.
