How do you calculate cure oven capacity?

Multiply the fastest curing speed, heated length divided by required minutes, by hanging density. At 120 ft and 13 minutes that is 9.23 ft/min and 369 parts an hour.

Why does this page exclude uptime and yield?

They are line properties, not oven physics. The oven sets a physical ceiling; the line throughput page discounts it to a realized rate.

What is the required time in the oven?

Part heat-up plus the TDS hold, both at metal temperature. A bracket needing 3 minutes to reach 400 °F with a 10-minute hold requires 13 minutes inside.

How do I raise a cure-limited line's capacity?

Hang denser first, since parts per hook scales the ceiling linearly. Then tighten pitch, run a hotter schedule if the TDS allows, and only then lengthen the oven.

Find the throughput ceiling the oven sets. Enter the heated length, the required minutes, the hook pitch and the parts per hook.

What this calculator does

Compute the throughput ceiling the oven itself imposes: the fastest speed that still delivers the cure schedule.

Formula used

Fastest curing speed = heated length ÷ required time in the oven
Cure-limited capacity = fastest speed × 720 ÷ hook pitch × parts per hook
Hooks inside the oven = heated length × 12 ÷ hook pitch
Parts inside the oven = hooks inside × parts per hook

Inputs explained

Usable Heated Oven Length: Conveyor path inside the heated zone, seal to seal.
Required Time in the Oven: Part heat-up plus the TDS hold at metal temperature.
Hook Pitch: Center-to-center hook spacing on the conveyor.
Parts per Hook: Parts each hook or carrier holds through the oven.

How to use the result

Best suited to checking a rate target against the oven, pricing rack density as capacity, sizing how much oven a target needs.
This is the oven's ceiling, not the line's rate; the line throughput page applies the haircut. Zoned ovens with staged temperatures need the datalogger's total-time judgment. Very tight pitches can depress zone temperature through air-seal losses.

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).
