Ultrasonic Cleaning Time at 21% loading, dwell, and rinse allowance: a worked example

Push loading, dwell, and rinse allowance up to 21% and the picture changes. This example computes every intermediate figure at that operating point. Use it when a process engineer or estimator needs to schedule ultrasonic tank capacity for precision parts.

The inputs for this scenario

  • Baskets or fixtures to clean: 36 baskets (unchanged)
  • Ultrasonic throughput rate: 0.18 baskets / min (unchanged)
  • Loading, dwell, and rinse allowance: 21 % (raised for this scenario; the documented default is 18)

Working through the calculation

  • Applying the documented formula (Base ultrasonic cleaning time = baskets or fixtures to clean รท ultrasonic cleaning completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 242 min for required ultrasonic cleaning time, the number this scenario is built around.
  • At this operating point the engine returns 200 min for base ultrasonic cleaning time.
  • At this operating point the engine returns 21 % for loading and dwell allowance.
  • At this operating point the engine returns 0.18 pieces / min for ultrasonic cleaning completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where loading, dwell, and rinse allowance sits at 18% and the headline result is 236 min, this scenario comes in 2.54% above the baseline at 242 min.
  • It computes base cleaning time as basket count divided by throughput rate, then inflates it by a loading, dwell, and rinse allowance to give a realistic required time. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required ultrasonic cleaning time: 242 min (headline result)
