Can Ultrasonic Cleaning Damage Parts

When cavitation is too aggressive

A very low frequency or high power on a delicate surface can mark or erode it, especially over long times. Frequency and power are matched to the part.

Higher frequency and gentle settings protect delicate work.

• Frequency too low
• Power too high
• Cycle too long

Chemistry and temperature damage

Wrong chemistry or excessive heat can stain, etch or alter some alloys, particularly aluminum. The chemistry and temperature are validated against the material.

Parts are rinsed and dried promptly.

• Staining and etching
• Heat effects
• Material compatibility

Mechanical damage

Parts that rub against one another or the basket can be mechanically damaged, even though the ultrasound itself is not the cause. Use dividers and proper loading.

Heavy parts need matched baskets and handling.

How to avoid it

Run a trial on a representative part with the intended settings, then inspect using the same method as production.

Document the accepted frequency, chemistry and temperature.
