Tooling Capacity Calculator

Estimate good parts a tool can deliver in its scheduled window. Enter active positions, actual running cycle time, stop hours, yield and demand.

What this calculator does

  • Check tooling good-part capacity against assigned demand using scheduled time, cycle time, stops and first pass yield.

Formula used

  • Running hours = scheduled hours − stop hours
  • Gross running output = running hours × 3,600 ÷ running cycle seconds × parts per cycle
  • Good part capacity = gross running output × first pass yield ÷ 100
  • Stop loss = stop hours × 3,600 ÷ running cycle seconds × parts per cycle
  • Demand headroom = good part capacity − required good parts

Inputs explained

  • Parts per Tooling Cycle: Active part positions from the die or mold layout.
  • Running Cycle Time: Representative actual cycle time while running from the production log.
  • Scheduled Tooling Hours: Planned production window before changeovers, maintenance and other stops.
  • Planned and Unplanned Stop Hours: Expected stops inside that production window from comparable run records.
  • First Pass Yield: Good parts divided by total parts for comparable runs.
  • Required Good Parts: Good-part demand assigned to this tool in the scheduled window.

How to use the result

  • Best suited to production window Check, tooling demand allocation.
  • This does not certify die life, mold life or machine suitability. A single cycle time cannot represent a mixed product schedule without a justified average.

Current U.S. benchmarks

  • The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
  • The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).

Common questions

  • Should I enter an ideal or actual cycle time? Enter representative actual cycle time while running. An ideal time without a performance loss input can overstate the capacity you can schedule.
  • Do changeovers belong in stop hours? Yes, when they occur inside the scheduled production window. Include maintenance and other planned stops on the same basis.
  • Why are good parts fractional? They are an expected quantity from an average yield. Use a conservative whole-part commitment and review variation before promising the output.
  • Does this calculate the tool's remaining life? No. It estimates output in a time window. Use the die life estimator with stroke counters and an approved service limit for remaining tool life.
