Plating, Anodizing & Surface Treatment calculator

Surface Treatment Yield Calculator

Measure parts accepted after their first treatment attempt without rework or repeat inspection. Compare the matched process population with your entered first-pass yield target.

What this calculator does

  • Measure parts accepted after their first treatment pass and compare the observed yield with your entered target.

Formula used

  • First-pass yield = parts accepted on the initial attempt ÷ initial processed population × 100
  • Yield gap = entered target − observed first-pass yield
  • First-pass loss parts = initial processed population − first-pass accepted parts

Inputs explained

  • Conforming First Pass Parts: Parts accepted without stripping, reprocessing, repair or repeat inspection.
  • Total Parts Processed: Matching parts completing their initial treatment attempt.
  • Target First Pass Yield: Your required first-pass yield for the same process and population.

How to use the result

  • Best suited to initial treatment yield review, reprocessing loss comparison.
  • Yield does not measure coating thickness, durability or process qualification. Does not predict future yield or final shipped yield after recovery.

Current U.S. benchmarks

  • The producer price index for industrial chemicals stands at 336.006 (BLS, Aug 2026), up 13.3% 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).

Common questions

  • Can a stripped and replated part count as first pass? No. Recovery after stripping or replating belongs outside the initial first-pass accepted count.
  • Should retested parts count as first pass? Exclude parts needing repeat inspection under this first-pass convention. Record the recovery separately.
  • Can zero parts pass the first attempt? Yes. A positive processed population with zero first-pass acceptances gives zero yield.
  • Does meeting the target approve the coating? No. The target comparison describes the entered population. Product acceptance still follows the specified inspection and performance criteria.
