How do you calculate feed pitch throughput on a press line?

Divide good parts by press uptime to get raw throughput, then multiply by line efficiency. With 1,200 parts over 8 hours you get 150 parts/hr raw, and at 90% efficiency that becomes 135 effective parts/hr.

What is a good line efficiency for a progressive stamping press?

Well-run progressive lines running steady coil stock typically hold 85-92% efficiency once misfeeds, splices and minor stops are counted. Below 80% usually points to feed-timing or die-maintenance problems.

Why is effective throughput lower than raw throughput?

Raw throughput assumes every stroke makes a good part. Effective throughput discounts scrap, misfeeds, jam clears and feed hesitation, which is why 150 raw drops to 135 effective at 90% efficiency.

Feed pitch vs stroke rate — what's the difference?

Stroke rate is strokes per minute the press physically runs; feed-pitch throughput here is the good, sellable parts per hour after efficiency losses, which is the number that matters for delivery commitments.

How do I raise effective feed-pitch throughput?

Attack the efficiency term first: reduce misfeeds with better feed-roll grip, cut coil-splice downtime, and tighten die maintenance. Raising 90% to 95% on a 150 raw rate adds about 7 parts/hr with no faster stroking.

Does this account for die changes?

Only indirectly. Uptime should be the actual running time; if you include changeover minutes in uptime, lower your efficiency figure or exclude those minutes to keep the number honest.

Feed Pitch Calculator

Feed Pitch on a progressive stamping line is the effective throughput a press-and-feed system actually delivers once you discount raw stroke rate by real line efficiency. Die-setters, press-line supervisors and manufacturing engineers use it to compare theoretical press speed against what the coil feed, straightener and part-eject rates truly sustain over a shift. It matters because a 150-part-per-hour raw rate that only holds 90% efficiency yields 135 usable parts, and that gap drives quoting, capacity planning and whether you hit the customer's line-side pull.

What this calculator does

Feed Pitch on a progressive stamping line is the effective throughput a press-and-feed system actually delivers once you discount raw stroke rate by real line efficiency.
Use it when feed pitch in sheet metal stamping and press lines is being committed and you need a throughput number you can defend.
It computes effective parts-per-hour throughput for a stamping press line by dividing good output by uptime, then scaling by line efficiency.

Formula used

Raw feed pitch = completed output ÷ runtime
Effective feed pitch = raw throughput × efficiency

Inputs explained

Good parts stamped this run:
Press line uptime:
Line efficiency (OEE-adjusted):

How to use the result

Use it when validating a new die's feed-pitch settings, sizing coil consumption, or checking whether a press can meet a release quantity within available shift hours.
It assumes a steady-state stroke rate; short die-change stops, coil-splice slowdowns and misfeed jams are only captured to the extent they are baked into your efficiency figure.

Current U.S. benchmarks

The producer price index for steel mill products stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. Quotes priced off last quarter's material cost miss this move.
U.S. iron and steel imports ran $2.1B in May 2026 (Census International Trade). The U.S. ran a trade deficit of $0.4B in the category that month. Import volumes are the pressure gauge behind tariff and reshoring decisions.
The U.S. has 53,790 fabricated metal products establishments employing about 1,441,471 workers (Census County Business Patterns, 2023).
