Why 40 kHz Ultrasonic Transducers Are Used by Manufacturers in Cleaning Applications

Ultrasonic cleaning systems offer significant advantages to manufacturers over traditional chemical-based cleaning methods. Ultrasonic cleaning systems provide lower operational cost savings since they don’t use harsh cleaning chemicals that require compliance with environmental regulations. They are also clean faster and are more effective in removing surface containments and residues from irregularly-shaped surfaces of components or devices. Before purchasing an ultrasonic system a customer first needs to determine which frequency will work best for their cleaning application.

 

Ultrasonic cleaning systems operate at frequencies that range between 20 kHz and 200 kHz. The cleaning system consists of a generator, transducer and a cleaning tank. The transducer generates ultrasonic waves that produce bubbles in the water of the cleaning tank. At lower frequencies larger bubbles are created that provide more intensive cleaning while smaller bubbles are created at high frequencies which clean more gently. A 40 khz ultrasonic transducer generates mid-range to large bubbles which effectively cleans a wide range of manufactured parts that is needed by manufacturers.

The nature of contamination or dirt on the parts or components to be cleaned will determine which frequency will work best for ultrasonic cleaning. Robust parts that have heavy deposits to be removed will require a lower frequency with intensive cleaning. Delicate parts with only dirty film or microscopic particles will need to be cleaned at high frequencies. The mid-range 40 khz ultrasonic transducer combines the most desirable features of both extremes.

In cleaning applications an ultrasonic transducer operating at 40 kHz can effectively clean industrial devices, machined parts, ceramics, jewelry, hard disk drive parts, wires and glass parts such as lenses. Both light films heavy contaminations are effectively removed without damaging the surface of the parts that are cleaned.
