Cleaning of drawn profiles, rods, bars and tubes (and degreasing, or "polishing" to remove a thin surface layer), currently achieved using solvents and brushes, can be much more efficient if high intensity ultrasonic sources are used. Traditional ultrasonic cleaning normally operates at between 10 and 30 Watts of radiated ultrasonic power per liter of cleaning liquid. Modern ultrasonic cleaning systems can increase this ultrasonic radiating power by 10 to 100 times, offering more efficient cleaning without using Perchlor and Trichlor. High power ultrasound can also penetrate into interior spaces, eg. inside a tube if it is completely immersed in a cleaning liquid.
MPI Advanced Multifrequency Ultrasonic Cleaning (wide spectrum - 100 Hz up to 1 MHz, sweeping ultrasonic waves) is bringing a new dimension to ultrasonic cleaning.
