Ultrasonic Cleaning and Degreasing:
|
Ultrasound is used widely throughout industry for
removing problem contamination from all forms of hard
surfaces, such as metals, plastics and ceramics. Its
unique properties can be harnessed to clean items of
all shapes, sizes and technical complexity,
penetrating holes and cavities that are impossible to
reach using ordinary cleaning methods. |
 |
The principle of the process is as follows. Piezo
electric transducers are attached to the cleaning
tank. They generate ultrasound waves that vibrate the
cleaning fluid at very high velocity, creating a
process called cavitation. Millions of tiny bubbles
implode within the solution and penetrate into every
orifice of the item being cleaned, removing dirt and
grime within seconds.
MM Plating Supplies offer a range of ultrasonic
cleaning and degreasing units as follows:
Generators
Our Units are supplied with robust and powerful
generators with a choice of standard frequency,
frequency sweep or bar frequency modes, offering a
wide selection of cavitational intensities to suit
different forms of cleaning.
The generators include versions that are totally
sealed from harsh environments, either in the
atmosphere or as a result of 'dirty' power supplies.
This ensures uninterrupted performance , even with
power spikes of up to 2500 volts.
In addition, the standard generators feature ES
environmental cooling. This system dispenses with
fan assisted forms of cooling which suck in
pollution from the outside atmosphere. As a result,
there is considerably less risk of generator
failure.
Finally, each generator has its own, independent
output indicator, making it easy to detect and
isolate defective performance and to reduce machine
down time.
Transducers
The machines are constructed using ultrasound 'bar'
transducers as opposed to conventional 'cone'
transducers. These have a 50% greater contact area
with the outside surface of the tank. This factor
substantially reduces the risk of 'hot spot' erosion
and stress cracks to the metal surface and provides
more uniform cleaning.
The transducer bar is not just bonded to the tank,
but has a unique centre-bolt mechanical fixing to
ensure long lasting adhesion.
The transducers are made of high quality
phosphor-bronze/silver construction in order to
minimise heat build up, thus extending the life of
the transducers and piezo electric crystals.
Ease of Service
Custom designed tanks can be made to order without
the customer having to suffer the penalty of high
cost for non-standard requirements.
