Plating, Anodizing & Surface Treatment worked example
Electroless Nickel Cost at 86% bath utilization efficiency: a worked example
What does the result look like when bath utilization efficiency reaches 86%? The full calculation is worked below with real intermediate numbers. Use it when quoting EN plating to a target thickness and you need to capture the high chemistry cost and limited bath life.
The inputs for this scenario
- Plated Surface Area: 250 sq ft (unchanged)
- Deposit Cost per Square Foot: 3.2 $/sq ft (unchanged)
- Bath Utilization Efficiency: 86 % (raised for this scenario; the documented default is 75)
- Bath Makeup Charge: 180 $ (unchanged)
Working through the calculation
- Applying the documented formula (Total = plated surface area x deposit cost per sq ft x bath utilization efficiency% + bath makeup charge) to the inputs above produces each figure below.
- At this operating point the engine returns 868 $ for total electroless nickel cost, the number this scenario is built around.
- At this operating point the engine returns 3.47 $ / piece for electroless nickel cost per unit.
- At this operating point the engine returns 688 $ for variable electroless nickel cost.
- At this operating point the engine returns 180 $ for fixed electroless nickel cost adder.
How this compares with the baseline
- Against the tool's baseline example, where bath utilization efficiency sits at 75% and the headline result is 780 $, this scenario comes in 11.28% above the baseline at 868 $.
- A figure at this level is achievable when bath utilization efficiency is genuinely sustained, not just peaked for a shift. It treats deposit cost per square foot as a flat rate; real EN cost rises sharply as bath turnovers accumulate and metal turnover (MTO) degrades plating rate, so actual late-bath cost can exceed this estimate.
