Gaskets, Seals, O-Rings & Elastomer Components worked example

Rework Cost at 72% rework allocation share: a worked example in gaskets, seals, o-rings & elastomer components

This worked example runs the rework cost numbers for a tougher week than the baseline: 72% rework allocation share instead of the typical 100%. Estimate rework cost for gaskets, seals, O-rings, and elastomer components requiring trim, sorting, cleaning, dimensional recovery, relabeling, or retest.

The inputs for this scenario

  • Elastomer parts needing rework: 420 parts (held at the documented default)
  • Rework cost per part: 1.65 $ / part (held at the documented default)
  • Rework allocation share: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed containment cost: 600 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable rework cost = elastomer parts needing rework × rework cost per part × rework allocation share.
  • Total rework cost works out to 1,099 $ at these inputs, and this is the headline figure for the scenario.
  • Rework cost per affected part works out to 2.62 $ / piece at these inputs.
  • Variable rework cost works out to 499 $ at these inputs.
  • Fixed containment cost works out to 600 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where rework allocation share sits at 100% and the headline result is 1,293 $, this scenario comes in 15.01% below the baseline at 1,099 $.
  • Use it during a quality containment or NCR to total the financial impact of reworking parts before deciding whether to rework, scrap, or deviate. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

  • Total rework cost: 1,099 $ (headline result)
