Understanding Ultrasonics: Precision Parts Washing Explained

Date: 3 March 2025 | Category: Other articles

Traditional parts cleaning methods struggle to balance thoroughness with efficiency, often requiring labour intensive effort, incurring excessive downtime, or using harmful chemicals that can degrade parts. The conventional approach to parts cleaning is no longer sufficient. It’s time for a smarter, more efficient, and eco-friendly solution. 

Ultrasonic cleaners are a highly effective solution for removing contaminants from various surfaces using high-frequency sound waves. Unlike traditional parts washers, ultrasonic cleaning provides a non-invasive, precision clean that reaches even the most intricate details.

How Does Ultrasonic Cleaning Work?  

An ultrasonic washer operates using a process called acoustic cavitation. This is where high-frequency sound waves create microscopic bubbles in a liquid cleaning solution. The solution loosens the contaminant or soil, and as the bubbles collapse, they generate an intense scrubbing action that removes the contaminants from the surface of the part. 


Do Ultrasonic Cleaners Work?
 

Ultrasonic cleaning is highly effective on a wide range of contaminants, including grease, dirt, oils, carbon deposits, and microscopic particles. The liquid cleaning solution and tiny bubbles can reach every part of the item being cleaned, giving a gentle yet thorough clean, even with very intricate parts. The cavitation process replaces the need for manual scrubbing and harmful chemicals, which means it is both safer and faster. 

 

Can Ultrasonic Cleaning Protect Parts?  

Unlike traditional cleaning methods that may involve brushing or scraping, ultrasonic cleaning is non-abrasive. This preserves the surfaces of expensive parts and precision components, reducing wear and extending life.  

Ultrasonic parts washers typically operate at between 50-60 degrees Celsius, which is a lower temperature than other parts washing methods.  Also, they do not use hazardous chemicals, meaning Ultrasonics is a gentler way to clean parts.

What Can You Clean with Ultrasonic Technology?  

Cleaning with ultrasound is particularly valuable when cleaning intricate, delicate or high value parts, or those soiled with grease or carbon. This includes:  

  • Metals: Stainless steel, aluminum, brass, titanium, and other alloys without damage.  
  • Plastics: Many durable plastics can be cleaned to remove oils, residues, and surface contaminants.  
  • Glass and Ceramics: Items like lenses, labware, and ceramic components can be cleaned without scratching, leaving them crystal clear. 


What Contaminants Can You Remove? 
 

Ultrasonic cleaning can be used to remove multiple contaminants and is particularly useful for:  

  • Oils and Grease: Including lubricants, cutting oils, and machining fluids.  
  • Dust and Dirt: General surface contamination from handling or the production environment.  
  • Carbonised Soils: Found on engine components, exhaust systems, and other items exposed to combustion processes.  
  • Mold Release Agents: Coatings used in rubber and plastic molding.  
  • Oxidation and Rust: Light rust and surface oxidation on metal components, especially in pre-treatment stages.  
  • Adhesives and Resins: Residues from bonding and assembly processes that can be challenging to remove manually.  
  • Metal Particulates and Chips: Small debris from machining, drilling, or grinding operations.  


What
Ultrasonic Cleaner Liquid Should I Use? 

Our parts cleaning experts will select the ideal ultrasonic cleaning fluid, cleaning time, and temperature for your needs. We also provide servicing, supply of fresh cleaning solution and waste collection at regular intervals. 


Can I Put Tap Water in an Ultrasonic Machine? 
 

Ultrasonic machines use water-based cleaning solutions, also known as aqueous solutions. The water is mixed with non-hazardous chemicals which loosen the contaminant ready for the cavitation bubbles to lift it off.  

While tap water works for some machines, purified water is gentler and more efficient. Our purified water technology removes 99% of impurities from standard water, which allows the cleaning chemistry to work more effectively. This makes the cleaning two times better and two times faster.
