Rubber Blank Yield at 99% target blank yield: a worked example

Push target blank yield up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when a die-cut gasket shop or rubber converter needs to know whether sheet layout, strip width, blank nesting, web scrap, or press setup is producing enough usable blanks before cutting or molding starts.

The inputs for this scenario

  • Usable rubber blanks: 232 blanks (unchanged)
  • Total blank positions or attempts: 250 positions (unchanged)
  • Target blank yield: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Rubber blank yield = usable rubber blanks ÷ total blank positions or attempts × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 92.8 % for rubber blank yield, the number this scenario is built around.
  • At this operating point the engine returns 6.2 points for rubber blank yield gap to target.
  • At this operating point the engine returns 232 count for usable rubber blanks.
  • At this operating point the engine returns 250 count for total blank positions or attempts.

How this compares with the baseline

  • Against the tool's baseline example, where target blank yield sits at 95% and the headline result is 92.8 %, this scenario lands almost exactly on the baseline at 92.8 %.
  • It computes the percentage of usable rubber blanks out of all blank positions attempted, plus the point gap between that yield and your target. 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

  • Rubber blank yield: 92.8 % (headline result)
  • Rubber blank yield gap to target: 6.2 points
  • Usable rubber blanks: 232 count
  • Total blank positions or attempts: 250 count
