Motion plus ultrasonics: Whether it is the finest, most complex workpieces or increased cleanliness requirements, ultrasonics are used as a complementary process to thoroughly remove particulate and film contamination. This works all the better with MAFAC rotating Ultrasonics.

Our patented technology increases the cleaning performance of high-frequency sound waves through motion: the ultrasonic module moves with the basket, ensuring that acoustic energy reaches all component surfaces evenly – without shadow zones typical of rigid systems. Critical geometries and heavy contamination can be targeted; delicate structures and sensitive surfaces are cleaned effectively and gently by reducing the acoustic input.

Complementary to the pressure-change technology MAFAC VAP, maximum technical cleanliness is achieved and strict industry requirements are reliably met. MAFAC rotating Ultrasonics is particularly suited for the validated cleaning of instruments in medical technology, the removal of finest particles in optics and laser industries, or the residue-free cleaning of complex geometries in semiconductor technology and additive manufacturing – even under cleanroom conditions.

Ultrasonic cleaning is based on the phenomenon of acoustic cavitation: sound waves at frequencies of 25 and 40 kHz are transmitted into the cleaning medium via an ultrasonic oscillator. The vacuum bubbles in the medium expand, collapse and finally implode at high speed. These mini-implosions release mechanical energy that acts in addition to the cleaning medium and the patented basket-nozzle rotation.

Typical of MAFAC, the ultrasonic oscillators emit pulses in rotation and move with the basket. Components are uniformly sonicated with full power from all sides and shadow zones are significantly reduced. Critical geometries and heavy contamination can be targeted and processed. Conversely, delicate structures can be cleaned effectively and gently by reducing the acoustic input.
