Thermal Spray, Hardfacing & Wear Coatings calculator

Spray Booth Throughput Calculator

Measure accepted coated output per occupied booth hour after subtracting affected parts. Enter completed and unaccepted part counts for one occupied-time window.

What this calculator does

  • Measure accepted coated output per occupied booth hour after subtracting affected parts.

Formula used

  • Accepted parts = Completed parts − Unaccepted parts
  • Accepted throughput = Accepted parts ÷ Occupied hours
  • Gross throughput = Completed parts ÷ Occupied hours
  • Output margin = Accepted parts − Target hourly output × Occupied hours

Inputs explained

  • Completed Coated Parts: Unique parts completing the booth during this observation window.
  • Parts Not Accepted: Completed parts still rejected or awaiting required rework.
  • Occupied Booth Time: Elapsed booth occupation including pauses, loading and setup.
  • Accepted Output Target: Required accepted output per occupied hour for this job.

How to use the result

  • Best suited to booth schedule reviews, accepted output commitments.
  • Work in progress and unaccepted parts do not contribute to accepted output.

Current U.S. benchmarks

  • Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.
  • 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

  • Should successfully reworked parts count as accepted? Yes, for final accepted throughput after the required acceptance decision. Keep first-pass performance separate and use a consistent disposition basis.
  • Should I multiply by utilization again? No. Using occupied elapsed time already includes interruptions inside that window.
  • Should parts awaiting inspection count as accepted? No. Keep them in unaccepted parts until the required acceptance decision is complete.
  • Can different coating recipes be compared directly? Only with their workload differences in view. Coating thickness, geometry and cooling requirements can change a valid production rate.
