Foundry & Forging calculator

Forging Press Utilization Calculator

Check whether the press achieved the operating-time target in its scheduled production window. Match the recorded press hours to that window before comparing periods or press groups.

What this calculator does

  • Compare measured press hours with scheduled availability and your own utilization target.

Formula used

  • Utilization = used machine hours ÷ available machine hours × 100
  • Target gap = target utilization − measured utilization
  • Unused scheduled hours = available hours − used hours

Inputs explained

  • Used Press Hours: Operating hours recorded for the stated machine group.
  • Available Press Hours: Scheduled hours summed for the same machines and dates.
  • Target Utilization: Utilization target from your production plan.

How to use the result

  • Best suited to press time review, production target comparison.
  • The ratio does not measure stroke speed, die loading or forging quality.

Current U.S. benchmarks

  • As of Aug 2026, U.S. manufacturing runs at 75.7% of capacity (Federal Reserve via FRED), down 0.1 points from a year earlier. Enter your own plant's utilization; the national figure is a reference point for how loaded the industry is.
  • The producer price index for steel mill products stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. Quotes priced off last quarter's material cost miss this move.
  • The U.S. has 3,569 primary metal manufacturing establishments employing about 354,911 workers (Census County Business Patterns, 2023).

Common questions

  • Should die-change time stay in the press schedule? Keep a die change in available hours when it occurs inside the scheduled production window. Removing it would hide that loss from the utilization comparison.
  • How should a press group be combined? Sum operating hours and scheduled hours for the identical set of presses, then divide the totals. Averaging their percentages gives the wrong weighting when schedules differ.
  • Does this measure press force or production speed? No. Operating hours establish time utilization only. Check force at the working stroke, cycle rate and accepted part counts with their own process records.
  • How do I set a useful press target? Use the planned operating share for the selected press schedule, including the expected tooling changes and billet supply. Revisit the target when that production mix changes.
