Ultrasonic systems are used to clean any product, from large machine castings,
gears and shafts, to the most delicate pieces such as electronic integrated
circuits. Equally efficient for cleaning metals, glass, ceramics, plastic.
Ultrasonic cleaning depends on cavitation, the rapid formation and violent
collapse of minute bubbles or cavities in a cleaning liquid. There are two different types of transducers that can be offered according
to the cleaning problems: MagnetostrictivennnnnnmnnElectrostrictive Electrostrictive made of Lead Zirconate Titanate and
other ceramics which change their phisycal dimensions, placed in a varying
voltage electrical field suitable when soft and delicate cleaning is required.
Magnetostrictive made of Nichel laminations that will
change dimensions in a varying magnetic field suitable when intense and strong
mechanical action is required. Recently Fismet Industriale has developped a special type
of ultrasonic transducer proper for rinsings. [Argomenti correlati]
The agitation by countless small and intense imploding bubbles creates a highly
effective scrubbing action that blasts the contaminant from the parts to be
cleaned.
Cavitation is produced by introducing high frequency (ultrasonic), high intensity
sound waves into a liquid.
The three essential components of any ultrasonic cleaning system are a tank
containing the cleaning solution, a transducer to convert electrical energy
and an ultrasonic generator.

These transducers utility has become necessary as at the end of ultrasonic
cleaning cycle pieces to be treated came out drenched with the detergent solution
as the ultrasonic action allows to obtain a better detergent solution penetration
inside the metal porosity. So it is necessary the same penetration action
during the rinsing cycle too in order to take away detergent residuals even
much depth.
Moreover the using of special ultrasonic transducers in rinsing allows to:
- Improve cleaning quality,
- Reduce rinsing water consumption,
- No residuals due to the entrainment in following bathes,
- Following beading treatments (electroplatings) best quality,
- Following beading treatments (electroplatings) long lasting.
- ultrasonic equipments working with detergent solutions
- ultrasonic equipments working with solvents
- ultrasonic systems
- automatic trasporters
- fittings
