New Ultrasonic Technology - Multi-Frequency Transducers, Precise Digital Waveform Control and Compact, High Efficiency Power Supplies

摘要

Recent advances in ultrasonic cleaning hardware have opened new opportunities for this useful technology in the plating industry. Ultrasonic frequency, identified as a major variable in applications requiring the removal of small particles from surfaces, continues to grow in range. Ultrasonic frequencies up to 170kHz are now readily available with higher frequency equipment already in use in some critical applications. Recognizing the benefits of lower frequencies for the removal of larger particles and the enhancement of chemical cleaning, equipment capable of generating a variety of frequencies from a single transducer bank in a controlled fashion has been developed. Precise delivery of frequency and waveform are combined to achieve the ultimate in cleaning while eliminating the possibility of exciting resonant modes of vibration in parts. Ultrasonic power supplies, once limited to 1,000 watts in a single unit are now available in 4,000 watt modules which reduce equipment size, complexity and cost in large applications.
