Ultrasonic Frequency Selection in Parts Cleaning

Q: Can I just use water with ultrasonics to get my parts clean?
A: In some cases, like fine particle removal, yes. However, typically some level of surfactant is desirable even in these applications
Q: Can I use standard off-the-shelf cleaning equipment for my application?
A: Standard 40kHz units may work well for your application, but always important to assess the risk of part damage
Q: What are multi-frequency systems and how can they help my cleaning processes?
A: Multi-frequency can allow for processing of different materials with different cleanliness specifications or sensitivity to damage.
Q: How do I know if my ultrasonic system is working properly?
A: Hydrophones are common quantitative tools for assessing effective cavitation. Pressure sensitive materials or liquid vials are another, more qualitative method.
