What is ultrasonic cavitation?
Cavitation is the rapid creation, and destruction, of tiny little vacuum bubbles or "cavities" in a liquid. "How on earth does that clean anything?" you may ask. Well the process is rather interesting. These little microscopic bubbles, when forced into contact with a solid surface, collapse. When they collapse, the surrounding liquid fires into the area the bubble once occupied, which creates an intense "scrubbing" action as the cleaning solution rushes against the object being cleaned. Just imagine it as millions of microscopic pressure washers blasting the object from all angles at once!
How do I know if my cleaner is working right?
Most poor cleaning usually results from improper control of one or more process variable(s); such as choosing the wrong detergent solution, insufficient heat, or not allowing enough time for the particular soil to be removed. If you suspect that your ultrasonic cleaner is not cavitating properly, there are two simple tests you can perform: the "glass slide" test and the "foil" test.
Why should I use an ultrasonic cleaner?
Why Ultrasonics? Primarily to clean more parts faster for less money! But let's take a closer look...
The best known advantages of ultrasonic cleaning:
- Precision - the ability to get into the tiniest places and get the dirt out. Some applications are only achievable via ultrasonics.
- Speed - Ultrasonics is faster than almost any other method for many jobs. This means less time in process, and more parts out the door.
- Labor savings - Often and entire assembly of sub-assembly can be cleaned without taking it apart.
- Consistent results - Get that machine set up properly, and ler it rip. Batch after batch of identically cleaned parts. One less variable for manufacturing and QC to worry about.
- Automation - You can set ultrasonic tanks directly into your production line, and make cleaning just another process step, instead of a time consuming off line process.
- The environment - using aqueous solutions means no solvents, no greenhouse gases, and recyclable cleaning solutions.
- Safety - Get rid of harmful solvent vapors and the smell!
