Rubber, Tires, Foam & Elastomer Manufacturing worked example

Rubber Sheet Yield at 99% target sheet yield rate: a worked example

What does the result look like when target sheet yield rate reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when rubber sheet yield in rubber, tires, foam and elastomer manufacturing needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Conforming rubber sheets: 8 count (unchanged)
  • Total rubber sheets inspected: 250 count (unchanged)
  • Target sheet yield rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Rubber sheet yield rate = rubber sheet yield count ÷ total rubber sheet yield population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for rubber sheet yield rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for rubber sheet yield gap to target.
  • At this operating point the engine returns 8 count for rubber sheet yield count.
  • At this operating point the engine returns 250 count for total rubber sheet yield population.

How this compares with the baseline

  • Against the tool's baseline example, where target sheet yield rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • A figure at this level is achievable when target sheet yield rate is genuinely sustained, not just peaked for a shift. It is a simple pass/fail ratio and does not weight defects by severity or salvageability, so a low yield may overstate loss if some rejects are reworkable.
