Conversion Coating Cost at 99% first-pass yield: a worked example
Push first-pass yield up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when quoting chromate or phosphate conversion coating on aluminum or steel parts and you need a defensible per-part and per-lot number.
The inputs for this scenario
- Parts Coated: 500 parts (unchanged)
- Coating Cost per Part: 1.85 $/part (unchanged)
- First-Pass Yield: 99 % (raised for this scenario; the documented default is 92)
- Line Setup Charge: 120 $ (unchanged)
Working through the calculation
- Applying the documented formula (Total = parts coated x coating cost per part x first-pass yield% + line setup charge) to the inputs above produces each figure below.
- At this operating point the engine returns 1,036 $ for total conversion coating cost, the number this scenario is built around.
- At this operating point the engine returns 2.07 $ / piece for conversion coating cost per unit.
- At this operating point the engine returns 916 $ for variable conversion coating cost.
- At this operating point the engine returns 120 $ for fixed conversion coating cost adder.
How this compares with the baseline
- Against the tool's baseline example, where first-pass yield sits at 92% and the headline result is 971 $, this scenario comes in 6.67% above the baseline at 1,036 $.
- It computes the total conversion coating run cost and the effective cost per part from parts coated, per-part coating cost, first-pass yield, and a one-time line setup charge. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
