Parts and contaminants · 4 min readCleaning threaded parts and blind holes with ultrasoundTapped holes, blind bores and internal threads trap chips, coolant and air. Why the trapped air is the real enemy, how part orientation, degassing and movement get the liquid in, which frequency suits fine threads, and how to get the liquid out again.
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.
Choosing a machine · 3 min readUMX Pro or ST series: two ways to build a 100-litre cleanerThe ST series is a floor tank with a separate generator cabinet; the UMX Pro is a cabinet with everything inside and a digital control panel. Same physics, different shop. Where each fits, with the overlapping models compared.
Operation and maintenance · 4 min readTroubleshooting: the machine runs but the parts are not cleanNine causes cover almost every case, and seven of them are the bath or the loading, not the machine. A checklist in the order that finds the fault fastest, from the sound of the tank to the generator display.
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.
Ultrasonic cleaning basics · 2 min readAnalog or digital generator?The same transducers, driven two different ways. What changes in daily use, and which one to specify.
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.Let's find the right fit
Not sure which size you need?
Send us the part, the quantity per hour and the soil you are removing. We will size the tank and the frequency with you.
