Why Medical Equipment Manufactures Use Ultrasonic Cleaning

Medical equipment used for testing and analysis has to be free from dirt and contamination if the results are to be accurate. Thus, it has to be cleaned thoroughly and to the highest standards, while making sure that the cleaning process would not cause structural damage to them. Commonly used sterilization techniques such as steaming will cause electronics failure, while mechanical scrubbing can damage delicate parts.



That's why specialized medical ultrasonic cleaners are the best solution to remove all surface contaminants quickly and effectively. Ultrasonic cleaning also complements other sanitary medical practices and provides an all-purpose method of cleaning manufactured medical components.



The ultrasonic cleaning method works by the cavitation bubbles created in the cleaning solution from ultrasonic sound waves generated by a medical ultrasonic transducer. The bubbles form in low-pressure areas and collapse at pressure peaks. As the bubbles collapse, they produce a tiny energetic jet of cleaning solution that dislodges surface dirt when it comes in contact with the surface of the part that is being cleaned.



Aside from the correct power, the key to a successful ultrasonic cleaning of medical parts is using the right frequency. Low frequencies generate comparatively large bubbles, high-energy jets, and robust cleaning action. High frequencies, on the other hand, generate smaller bubbles and more gentle cleaning. Depending on the level of surface hardness and the type and level of contamination, users can choose the frequency to clean as quickly as possible without damaging the part surface.



The microscopic cavitation bubbles and the jets that they create are active wherever the cleaning solution is present. That is why they can clean areas that mechanical scrubbing usually cannot reach – complex shapes, dead-end holes, and interior hollows. These jets dislodge and remove all dirt particles and contamination, resulting in a completely clean part surface.

Why Ultrasonic Cleaning Is Important to Automotive Manufacturers

Ultrasonic cleaning can remove impurities and contaminants from the surfaces of the machined components, sheet metal, and other items that are finished automotive parts. Such cleaning is required because many parts come out of the manufacturing process with oil, grease, or shop dirt on their surfaces.

There are traditional cleaning methods to clean automotive parts, such as heavy manual scrubbing, harsh cleaning chemicals, and extensive soaking. However, ultrasonic cleaning is the best method as it cleans automotive parts quickly and thoroughly. It’s also cost-effective and environmentally safe.

Ultrasonic cleaning uses microscopic cavitation bubbles to scrub surfaces and remove contaminants. The bubbles are generated by the action of ultrasonic waves in the cleaning solution, and their energy depends on the sound frequency. The automotive ultrasonic cleaners are configurable for the type of part, and contamination found.

In ultrasonic cleaning, the key to a successful cleaning of automotive parts is choosing the proper frequency. Low frequencies produce larger bubbles and more robust cleaning action, while higher frequencies produce smaller cavitation bubbles and gentler cleaning action. The bubbles are present anywhere in the liquid solution, which enables the cavitation bubbles to clean even inside holes, hollow curves, or inside bearings.

Low frequencies are better for cleaning rugged parts made of steel and other harder materials. High frequencies, on the other hand, are more appropriate for cleaning softer or delicate parts (such as aluminum or parts that are coated or treated), so that surface damage such as pitting can be avoided.

 When the right frequency is chosen, dirt and contaminants are entirely removed, leaving the machined parts, sheet metal parts, and other automotive assembly parts thoroughly clean. 

It is vital to have the automotive parts cleaned before assembly, which in turn can improve performance, durability, and resistance to failure. Some parts need to be cleaned before painting or coating. Automotive ultrasonic cleaners can be configured for the type of part and the kind of contamination to ensure quick and thorough cleaning before assembly or subsequent manufacturing steps.
