Fastener Manufacturing & Thread Rolling calculator

Sort Machine Output Calculator

Sorting output is driven by accepted pieces through the machine, not just bowl speed. This calculator converts sorted good pieces and actual run time into effective parts per hour after stops, rejects, bowl refills, and inspection checks are considered.

What this calculator does

  • Estimate effective optical or mechanical fastener sorting output from accepted pieces, run hours, and sorter efficiency.
  • Use it when planning thread, head, length, washer presence, crack, mix, or visual sorting capacity before shipment.
  • Turns accepted sorted pieces, run time, and efficiency into effective fastener sorting throughput.

Formula used

  • Raw sorting rate = accepted sorted fasteners ÷ actual sorter run time
  • Effective sorting output = raw sorting rate × sorter efficiency

Inputs explained

  • Accepted sorted fasteners: undefined
  • Actual sorter run time: undefined
  • Sorter efficiency after stops: undefined

How to use the result

  • Use it for containment planning, final inspection capacity, outside sorting comparison, or shipment recovery plans.
  • It does not identify reject types or account for manual review, refeed loops, mixed-lot controls, or downstream packaging limits.

Common questions

  • Should I enter total fed pieces or accepted sorted pieces? Use accepted sorted pieces when planning shipment output. Use total fed pieces only if you want to measure machine throughput before rejects.
  • What affects sorter efficiency? Bowl feed interruptions, camera alarms, reject bin handling, part mix, oil contamination, gauge checks, and operator response time can all reduce effective output.
  • Can this compare outside sorting quotes? Yes. Use comparable accepted output rates and include freight, setup, certification, and rework costs separately.
  • What decision does the result support? Use effective sorter output to estimate containment duration, decide whether to add shifts, or confirm whether sorting can clear parts before ship date.
