The ultrasonic cleaning process offers safe and highly effective cleaning of almost any object, regardless of size or complexity. There is a definite need for “precision” cleaning for many objects in many industries, which makes ultrasonic cleaners the method of choice for safely removing contaminants from almost any part including those made from glass, plastic, ceramic, and many other nonmetallic and metallic surfaces. While ultrasonic cleaners are the top choice for industrial level cleaning tasks, do we really understand how they work?
Ultrasonic cleaners: it’s all about the bubbles!
The core of ultrasonic cleaning is the bubble – or actually lots of bubbles. Millions of tiny bubbles are created by sound waves as those waves move through water. This process is known as cavitation, which is simply the formation of bubbles (or a cavity) in water. If you have ever seen the foam left in water by a spinning boat propeller, then you’ve seen cavitation in action.
How do all these bubbles work to clean objects?
The bubbles expand and then rapidly collapse. As they collapse, they release a significant amount of energy creating an intense “scrubbing” action which is effective on visible surfaces as well as small crevices and even the tiniest blind holes. Dirt can be loosened and removed from any surface that the liquid touches. The bubbles are small enough to penetrate even microscopic crevices, cleaning them thoroughly and consistently every time. In addition, the constant implosion produces tremendous vacuum energy in the form of heat and pressure. This action, or cavitation, occurs thousands of times every second to quickly produce the cleanest and dirt free parts. It’s this combination of heat and pressure which gives the ultrasonic cleaner its cleaning capability and power.
This powerful cleaning method is used to clean machinery, parts and tools in various industries including:
Unlike other cleaning processes and harsh chemicals, ultrasonic cleaning will not damage intricate, lightweight, or easily damaged parts. The result is also very fast and effective cleaning. These are some of the many reasons why the ultrasonic cleaning system is widely used across many different industries.
