FAT Checks for a Three-Tank Ultrasonic Cleaning Machine
Buyers should define measurable pass or fail checks for a three-tank ultrasonic cleaner before signing off at the factory, covering tank sequence, ultrasonic power, frequency, and cleaning results on metal parts.
Before accepting a three-tank industrial ultrasonic cleaning machine, decide how each tank's role will be proven at the factory acceptance test. Will tank one be checked for ultrasonic cleaning, tank two for rinse, and tank three for drying or final rinse? Ask the supplier to state the intended sequence and to demonstrate each stage with representative metal parts.
For the ultrasonic stage, confirm how the 1.8 kW ultrasonic power is verified and at which of the published frequency options, 28 or 40 kHz, the test will run. Treat these catalog values as reference points, not guarantees for the supplied unit. Ask whether the acceptance test includes a repeatable soiled-part sample, a defined inspection method, and a record of settings.
Useful pass or fail questions include: does the machine complete the full three-tank cycle without operator intervention; are timer and temperature settings repeatable; and do cleaned metal parts meet the buyer's agreed visual or residue criteria? Define sample size and who judges results.
Before requesting a quote, confirm with the supplier which tests they will run, what instrumentation and records they provide, and how deviations are resolved before shipment.
