How do you calculate masking labor cost?

Multiply masked features by labor per feature and by the masked share, then add the material and demask adder. With 6 features at $0.85, 100% masked, plus a $1.20 adder, total masking cost is $6.30, or $1.05 per feature.

Why is masking so expensive relative to the coating?

Masking is hand work that doesn't scale with automation the way tank processing does. On a 6-feature part, $5.10 of variable labor plus a $1.20 adder can easily exceed the anodize or plate cost itself, which is why masking-heavy parts hurt margin.

What does the masked share percentage do?

It scales variable labor for cases where not every feature actually gets masked in a run. At 100% here, all 6 features are masked; drop it to 50% and variable labor halves from $5.10 to $2.55 while the fixed $1.20 adder stays put.

How can I reduce masking cost per feature?

Switch from hand tape to reusable custom plugs or caps, redesign to reduce masked features, or batch demask. Since $5.10 of the $6.30 here is variable, cutting per-feature time or feature count moves the total the most.

Should mask material be in the per-feature rate or the adder?

Put consumables that scale with feature count (tape, lacquer) into the per-feature rate, and one-time or per-part items (custom plugs, demask solvent, disposal) into the $1.20 adder so each driver is visible and correctly scaled.

What is a reasonable labor cost per masked feature?

It varies with feature type, but simple plug or tape features often run $0.50-$1.50 in labor; the $0.85 used here is mid-range. Hand-lacquered edges or tight tolerances can run several dollars each.

Plating, Anodizing & Surface Treatment calculator

Masking Labor Cost Calculator

Masking labor cost captures what it really costs to protect the areas of a part that must stay bare during plating, anodizing, or painting. Estimators and process planners in surface-treatment shops use it because masking is stubbornly manual — tapes, plugs, caps, and lacquers applied and removed by hand — and it often dwarfs the cost of the coating itself on complex parts. Getting it right protects margin on quotes and flags parts where masking design should be simplified. This calculator separates the variable per-feature labor from the fixed material and demask adder so you can see both drivers.

What this calculator does

Estimate masking labor cost from masked features per part, labor per feature, the maskable share, and flat material or demasking adders.
Use it when a part has critical threads or faces that must stay bare during plating or anodizing and you need the masking labor priced.
It computes total masking cost as masked features times labor per feature times the masked share, plus a fixed material and demask adder, and then divides back to a cost per feature.

Formula used

Masking cost = features x labor per feature x maskable share% + material and demask adder
Cost per feature = masking cost / masked features per part

Inputs explained

Masked features per part:
Labor cost to mask one feature:
Share of features actually masked:
Mask material and demask cost adder:

How to use the result

Use it when quoting a masked part, deciding whether custom plugs beat hand-taping, or building a should-cost model for a masking-heavy job.
It uses one average labor rate per feature; parts mixing quick plugs with fiddly hand-lacquered edges will need a blended or per-feature-type estimate to stay accurate.

Current U.S. benchmarks

The producer price index for industrial chemicals stands at 344.336 (BLS, May 2026), up 16.1% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 14,543 chemical manufacturing establishments employing about 911,245 workers (Census County Business Patterns, 2023).
