This guide will walk you through everything you need to know about ultrasonic parts washers.
What is an Ultrasonic Parts Washer?
An ultrasonic parts washer is a cleaning system that uses high frequency sound waves in a liquid bath to remove contamination from parts. Unlike spray or immersion washers, ultrasonic systems clean without direct force or scrubbing.
How Does an Ultrasonic Parts Washer Work?
The process works at a microscopic level, using ultrasonic transducers which are fixed to the tank. They send sound waves through the liquid, usually at 20 to 40 kHz. These waves create millions of microscopic bubbles.
The bubbles collapse almost instantly. This action loosens and lifts contamination from the part surface. It works evenly across the part, even in areas you cannot see. This action is called cavitation.
The water can also be heated to help break down oils and grease faster. After cleaning, parts may be rinsed and dried. Some systems include these stages in one automated line.
What Can Be Cleaned with an Ultrasonic Washing System?
Ultrasonic washing systems are best suited to parts that need deep and even cleaning.
Automotive Parts
Engine parts, fuel injectors, gear components, and bearings.
Aerospace Components
Turbine blades, valves and hydraulic parts.
Medical Instruments
Surgical tools, implants, and dental equipment.
Manufacturing Parts
Machined parts, mould tools and fabricated components.
Types of Industrial Ultrasonic Cleaning Systems
Ultrasonic washers come in several formats, each designed for different workloads and environments.
Industrial Tank Systems – Large ultrasonic tanks are built for higher volumes and bigger parts. They can be used as standalone units or as part of a multi-stage cleaning line that includes rinsing and drying.
Single Tank Systems – These are often used for batch cleaning. Parts are cleaned in one tank, then moved for rinsing or drying. They suit lower volumes or flexible workflows.
Multi-Stage Ultrasonic Systems – These systems move parts through several tanks. A typical setup may include ultrasonic washing, rinsing, and drying stages. They are common in industries with strict cleanliness standards.
Automated Ultrasonic Washers – For high-throughput production, automated systems handle loading, cleaning, and unloading with minimal manual input. This improves consistency and reduces labour time.
Key Benefits
Deep and Even Cleaning
Cavitation reaches every exposed surface. It cleans inside holes and tight gaps that other methods cannot reach.
Shorter Cleaning Times
Ultrasonic washing systems clean faster than many traditional methods. This helps reduce bottlenecks in production.
Reduced Labour
Once the cycle starts, the machine does the work. Operators spend less time handling parts and scrubbing surfaces.
Gentle on Parts
There is no harsh brushing. This lowers the risk of scratches or wear, even on delicate components.
Lower Chemical Use
Many ultrasonic systems use mild, water-based solutions. This can cut down on solvent use and improve workplace safety.
Choosing the Right Ultrasonic Parts Washer
Selecting the right industrial parts washer starts with understanding your cleaning needs. Think about the size, material, and level of contamination of your parts. Remember, parts with fine details or internal passages benefit most from ultrasonic cleaning.
You’ll also need to consider:
- Tank size and load capacity
- Ultrasonic frequency
- Cleaning chemistry
- Cycle time and temperature
- Rinsing and drying needs
