Electronic industrializationIndustrial ultrasonic cleaning, why you should know about it

January 3, 20240

Ultrasonic cleaning is a highly effective and powerful method for cleaning a wide variety of parts, mainly in industrial environments. This process uses ultrasonic waves to remove the most difficult dirt, being environmentally friendly by not emitting polluting substances.

Some of the sectors where its use has spread include maintenance, aeronautics, optics, the pharmaceutical, textile, surgical, railway, dental, automotive industries, among others.

Ultrasonic cleaning is faster than conventional systems, increases the useful life and productivity of parts, and is especially effective for cleaning deep inside materials, leaving impeccable surfaces, even in hard-to-reach places. Therefore, it is important to know this method, as it offers an effective, environmentally friendly and versatile alternative for cleaning in various industrial sectors.


How does ultrasonic cleaning work?

Ultrasonic cleaning is based on the use of high-frequency longitudinal waves, commonly known as “sound”. These waves generate overpressure and depressure in the liquid that surrounds the piece, triggering a phenomenon known as cavitation.

Cavitation involves the formation of bubbles inside the liquid. Consequently, this tensile force breaks the ionic and mechanical bonds of the dirt particles present on the surface of the parts, thus ensuring the complete removal of any trace of dirt, even in hard-to-reach areas, completely dissolving in the liquid.

These bubbles play a similar role to millions of tiny brushes that scrub dirt with great intensity.

What factors are involved in ultrasonic cleaning?

Ultrasonic cleaning works differently depending on the type of dirt you are dealing with and therefore requires that you configure the cleaning process in a personalized way to ensure complete cleaning.

Liquid to use

Each piece requires a specific cleaning product, depending on the cleaning time required, the material of the piece, type of dirt, etc. It is very important to be able to detect the quality of the liquid in real time since it varies depending on the dirt and the number of cleaning cycles. Ph variations are a good indicator of the state of the cleaning solution.

It is what determines the size of the bubbles produced in cavitation (commonly they are wavelengths between 20-40 kHz).

For example, when dirt is heavier, it requires a lower frequency and greater grinding power, while for delicate items such as jewelry, higher frequencies are required. It is very important that the electronic control guarantees real frequency values, without variations.


A temperature of the cleaning liquid between 80ºC and 90ºC facilitates the formation of bubbles and steam pressure, which improves cleaning efficiency.


Defining the time during which the piece will be submerged in the cleaning liquid to be subjected to cleaning is essential to guarantee complete removal of dirt without damaging the material.

It is important that the electronic board is robust when recording these parameters and that it has IoT connectivity.

In this way, you can store them on a cloud server and with them establish operating patterns, store historical records, do preventive maintenance and establish traceability of the parts that ensures quality in the cleaning process.

Industrial ultrasonic cleaners offer very important advantages over traditional cleaning methods:

Efficiency and speed: ultrasonic cleaning can clean very large parts in a matter of minutes, while traditional methods can take hours and require harsh chemicals.

Efficiency in removing contaminants: Ultrasonic cleaning is highly effective in removing surface contaminants, dirt, dust, oil, grease and chemical residues, even in hard-to-reach shapes and complex crevices.

Reduced environmental impact: Ultrasonic cleaners use tap water or mild detergents, minimizing the use of toxic chemicals and reducing environmental impact.

Worker Safety: They eliminate the use of harsh chemicals, making the cleaning process safer for workers.

Saves costs and time: Ultrasonic cleaning can lead to very significant savings, a reduction in the costs of repair and replacement of parts and allows the life of the equipment that assembles them to be extended, in addition to a lower environmental cost compared to other methods.

Gentle Cleaning Process: Ultrasonic cleaning is very gentle and extends the life of parts, making it suitable for delicate items that can be easily damaged by traditional methods.

In summary, industrial ultrasonic cleaners offer many advantages in terms of efficiency, effectiveness, environmental impact, worker safety and cost savings compared to traditional cleaning methods.

If we also add the possibilities that electronic design, 4.0 technology, and Big Data offer us today, we will have very robust, reliable equipment with the best cleaning quality.
