UV Curing worked example

UV Cure Rework / Scrap Cost with defective parts of 120 parts: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop defective parts to 120 parts, then walk the calculation through step by step. Total the rework / scrap cost for UV cure defects: rework labor, scrap material, and disposition / overhead - the dollars an undercure escape actually costs.

The inputs for this scenario

  • Defective parts: 120 parts (the input this scenario stresses; the baseline uses 240)
  • Rework or scrap cost per part: 8 $ / part (held at the documented default)
  • Disposition / containment labor: 650 $ (held at the documented default)
  • Overhead / customer impact: 300 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable cost = defective parts × cost per part.
  • Total cure defect event cost works out to 1,910 $ per defect event at these inputs, and this is the headline figure for the scenario.
  • Cost per defective part works out to 15.92 $ / defective part at these inputs.
  • Rework / scrap material works out to 960 $ at these inputs.
  • Disposition + overhead works out to 950 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where defective parts sits at 240 parts and the headline result is 2,870 $ per defect event, this scenario comes in 33.45% below the baseline at 1,910 $ per defect event.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to defective parts, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It is a snapshot of one event and does not model defect frequency or PPM rate over time, so multiply by your event count to estimate annual exposure.

Results at a glance

  • Total cure defect event cost: 1,910 $ per defect event (headline result)
  • Cost per defective part: 15.92 $ / defective part
  • Rework / scrap material: 960 $
  • Disposition + overhead: 950 $
