Plating, Anodizing & Surface Treatment worked example

Anodizing Cost per Part at 69% first-pass acceptance rate: a worked example

This worked example runs the anodizing cost per part numbers for a tougher week than the baseline: 69% first-pass acceptance rate instead of the typical 96%. Estimate anodizing cost per part from the area anodized, per-square-foot rate, first-pass acceptance, and flat sealing or rack-changeover adders.

The inputs for this scenario

  • Surface area anodized per part: 2.5 sq ft (held at the documented default)
  • Anodize price per square foot: 3.2 $/sq ft (held at the documented default)
  • First-pass acceptance rate: 69 % (the input this scenario stresses; the baseline uses 96)
  • Seal and rack changeover adder: 1.5 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Anodize cost = area x cost per square foot x acceptance% + seal and rack adder.
  • Total anodizing cost per part cost works out to 7.02 $ at these inputs, and this is the headline figure for the scenario.
  • Anodizing cost per part cost per unit works out to 2.81 $ / piece at these inputs.
  • Variable anodizing cost per part cost works out to 5.52 $ at these inputs.
  • Fixed anodizing cost per part adder works out to 1.5 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where first-pass acceptance rate sits at 96% and the headline result is 9.18 $, this scenario comes in 23.53% below the baseline at 7.02 $.
  • Use it when quoting anodized aluminum parts, evaluating a finishing vendor's rate, or deciding whether to bring anodizing in-house. 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.

Results at a glance

  • Total anodizing cost per part cost: 7.02 $ (headline result)
  • Anodizing cost per part cost per unit: 2.81 $ / piece
  • Variable anodizing cost per part cost: 5.52 $
  • Fixed anodizing cost per part adder: 1.5 $
