Plating, Anodizing & Surface Treatment worked example

Plating Defect Rate at 68% target maximum defect rate: a worked example

Suppose target maximum defect rate falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate plating defect rate for plating, anodizing and surface treatment using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Defective plated parts found: 8 count (held at the documented default)
  • Total plated parts inspected: 250 count (held at the documented default)
  • Target maximum defect rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Plating defect rate = plating defect rate count ÷ total plating defect rate population × 100.
  • Plating defect rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Plating defect rate gap to target works out to 64.8 points at these inputs.
  • Plating defect rate count works out to 8 count at these inputs.
  • Total plating defect rate population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target maximum defect rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes the defect rate as defective parts divided by total inspected, times 100, and reports the gap between that rate and your target. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
