What Is the Definition of Ultrasonic and Megasonic Frequency?

Sound exists at much higher frequencies, which includes both ultrasonic and megasonic ranges. While these may not be audible to human hearing, these frequencies can be used in practical applications in megasonic and ultrasonic cleaning systems.

So how do megasonic and ultrasonic cleaning systems work? When liquids and gases are subjected to high-frequency sound at powerful energy levels, it leads to the formation of microscopic tears in these mediums.

When megasonic or ultrasonic sound energy goes through these mediums, it causes the microscopic tears to form into bubbles every second, and these bubbles collapse quickly. This process is known as “cavitation.”

Cavitation bubbles are high-energy bubbles. As each of these bubbles forms and collapses quickly, it generates shockwaves. When you place an object into these cavitation bubbles, it tends to be subjected to the energy of these implosions. These cavitation bubbles are so powerful that they can dislodge dirt or other contaminants off the surface of the object exposed. This is the kind of phenomenon which both the megasonic and ultrasonic cleaning system approach utilizes.

The megasonic and ultrasonic cleaning approach is revolutionary. This cleaning approach is faster, more thorough and more efficient. Since megasonic and ultrasonic cleaning systems are contactless cleaning systems, they do not require the use of harsh cleaning chemicals or mechanical scrubbing as conventional cleaning methods do.

The ultrasonic and
megasonic cleaning system approach are also environmentally friendly, since neither use cleaning chemicals. In conventional cleaning methods, they require the application of an involved chemical disposal system to meet compliance with environmental laws.
