How do you calculate powder coat conveyor speed?

Multiply target output by hook pitch, then divide by line efficiency. At 400 parts/hr, 18 in pitch and 90% efficiency the calculator returns 11.11 in of spacing-derived speed and an effective throughput requirement of 444 pieces/hr to net your target.

What is a good hook pitch for a powder line?

Pitch should exceed the widest part dimension plus swing clearance so parts do not touch in the booth or oven. Typical small-part lines run 6-12 in, general fabrication 12-24 in; 18 in is a common general-purpose default.

Why is my effective throughput higher than my target output?

Because efficiency is below 100%. To net 400 good parts/hr at 90% efficiency you must load and move parts as if producing 444/hr, since roughly 10% of capacity is lost to gaps, rejects and load/unload variance.

Does faster line speed hurt cure quality?

It can. Increasing speed shortens oven dwell. If your required speed pushes dwell below the powder's cure schedule (e.g. 10 min at 400F metal temp), you must lengthen the oven, add a second oven pass, or reduce pitch instead of chasing speed.

Line speed vs hook pitch — which do I change to hit rate?

Change pitch first if oven dwell is your constraint: tighter pitch adds parts per foot without adding speed. Change speed only when dwell headroom exists. This calculator shows both so you can trade one against the other.

How does line efficiency affect the number?

Efficiency divides into the requirement, so lower efficiency inflates required throughput. Dropping from 90% to 80% would raise the effective requirement from 444 to 500 pieces/hr for the same 400-part target.

Finishing calculator

Hanging Spacing Calculator

Hanging spacing determines how fast your powder coat conveyor must run to hit a target production rate given the pitch between hooks or racks. Finishing line engineers and production planners use it to match line speed, oven dwell and cure schedules before a run starts. Get it wrong and parts either under-cure at high speed or the line starves and burns oven gas on empty hooks. It is the first number you set when balancing a monorail or power-and-free finishing system.

What this calculator does

Calculate hook spacing needed for target line output at a given conveyor pitch and efficiency.
Use this calculator for practical powder coating or surface finishing planning, quoting, troubleshooting, or line setup.
It computes the conveyor speed in inches per minute of travel needed to move enough hooks past the coating and cure zones to meet a target hourly output at a given hook pitch and line efficiency.

Formula used

Required speed = target output × pitch ÷ efficiency
Converted result uses the displayed unit

Inputs explained

Target line output:
Hook spacing or pitch:
Line efficiency:

How to use the result

Use it when commissioning a finishing line, changing part mix, or diagnosing why a batch is missing rate — before you touch the drive VFD.
It assumes one part per hook at the stated pitch; multi-part racks, mixed pitches, or oven dwell limits can override the speed this calculator suggests.

Current U.S. benchmarks

Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
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).
