Ultrasonic Cleaning Trials: Test Your Own Workpieces
Buyers of a three-tank industrial ultrasonic cleaner should require a demonstration using their own metal parts, then compare results against agreed acceptance criteria before ordering.
Make the demonstration a pass/fail condition of the purchase: require the supplier to clean your own metal workpieces in the proposed three-tank machine, not sample parts chosen by the seller. Ask how parts will be fixtured, how soiled they may be, and how cleanliness will be judged, such as visual inspection under agreed lighting or a residue check you define.
Compare the published 28 kHz and 40 kHz options on your actual parts. Which frequency does the supplier recommend for your geometry and soil, and can the demonstration run at that setting? Note that 1.8 kW ultrasonic power is a catalog reference value, not a guarantee for your load; ask how it is distributed and whether it suits the basket size you need. Confirm the three-tank sequence and what each stage does with your material.
Before requesting a quote, confirm with the supplier that the demonstration uses your workpieces and production soil, which frequency and power settings will be used, how cleanliness will be measured, and whether the tested configuration matches what will be delivered.
