Ultrasonic cleaning basics · 3 min readCavitation: how a collapsing bubble cleans a surfaceUltrasound does not scrub. It makes millions of microscopic bubbles grow and collapse against the part every second, and the collapse does the work. What happens in the liquid, and what it means for the settings you choose.

Ultrasonic cleaning basics · 3 min readUltrasonic power density: watts per litre, and why big tanks need fewerDivide the ultrasonic power by the tank volume and you get the figure that predicts how hard a tank cleans. Our range runs from about 9 to 40 W per litre, and the spread is deliberate. How to read the number when comparing machines.

Operation and maintenance · 3 min readThe foil test: a one-minute check of cavitationA sheet of household aluminium foil in the bath for sixty seconds shows where the tank cleans and where it does not. How to run it, what the hole pattern means, and how to use it as the acceptance test for a new machine and the monthly check for an old one.

Ultrasonic cleaning basics · 3 min readSweep and degas: what the two buttons on a digital generator doSweep moves the frequency a little either side of nominal so no part sits in a dead spot; degas drives dissolved air out of a fresh bath so cavitation can start. When to use each, and what happens if you do not.

Process and parameters · 4 min readChoosing the cleaning temperatureHeat speeds up the chemistry and thins the oil, but above about 80 °C cavitation weakens. Where to set the bath for oil, carbon, machining residue, flux and biological soil, and why our tanks heat to 100 or 110 °C when most cleaning happens at 50 to 65.

Process and parameters · 2 min read28 kHz or 40 kHz: which frequency cleans your part?Lower frequency hits harder, higher frequency reaches further. The part, the soil and the surface decide.

Ultrasonic cleaning basics · 2 min readWhat is ultrasonic cleaning?Sound above hearing range, a liquid, and millions of collapsing bubbles: the short version of how an ultrasonic cleaner works and what it is good at.

Ultrasonic cleaning basics · 17 min readUltrasonic cleaning explained: waves, cavitation, generators, tanks and featuresThe long version: how ultrasonic waves make cavitation, what frequency and temperature do, how generators and transducers are built, and which features matter in a tank.

Ultrasonic cleaning basics · 2 min readHow ultrasonic cleaning actually worksTransducers turn electrical energy into pressure waves, the waves make cavitation bubbles, the bubbles collapse against the part. Step by step.

Process and parameters · 2 min readAgitation in ultrasonic cleaningMoving the basket while the ultrasound runs exposes every face of the part to fresh cavitation and stops standing-wave shadows. When it helps and how the lift does it.

Ultrasonic cleaning basics · 2 min readUltrasonic cleaning versus traditional cleaning methodsHand scrubbing and soaking compared with ultrasonic cleaning on effectiveness in hard-to-reach areas, speed, ease of use and environmental impact.

Ultrasonic cleaning basics · 2 min readWhy ultrasonic cleaning reaches where brushes cannotCavitation cleans blind holes, threads and internal passages that scrubbing and soaking leave dirty. What the process is, where it is used and what to expect.
