Often cleaning is needed as part of assembly, manufacturing or repair processes. But cleaning items thoroughly and removing all contamination can sometimes involve aggressive processes or strong chemicals which risk doing damage to the item being cleaned. An ultrasonic cleaner offers a kinder but effective alternative that ensures items are cleaned properly but with minimal risk of damage.
An ultrasonic cleaner works by immersing the object to be cleaned in water or a solvent and then using ultrasound to agitate the liquid and create bubbles. These bubbles are able to get into all of the cracks and crevices of the object and lift off dirt and contaminants.
Using an Ultrasonic cleaner can remove corrosion, grease, limescale, bacteria and more. The process can also work on a wide range of materials, including metals, ceramics, plastics and rubber. Depending on the equipment used, it can also be used to clean items of different shapes and sizes.
An ultrasonic cleaner has a chamber or tank to contain the fluid and the work piece. There's usually a basket - similar to that used in a deep-fryer - to allow items to be safely inserted and removed from the machine. A transducer is used to create the ultrasound waves using an oscillating electrical frequency.
Ultrasonic cleaners can range in size from compact desktop units to much larger models for use in factory and workshop environments. Automated versions are available for use as part of process environments, with simpler versions for one-off cleaning tasks in workshop and repair situations.Ultrasonic Advantages
Cleaning using ultrasound has a number of benefits. First of all, it's fast: the process generally takes no more than a few minutes. It's also better for the environment, as it cuts down on the need to use harsh chemicals but is able to provide more effective cleaning than water alone.
The technology is popular with industries that handle small components - such as jewellers and watch-makers. It's also useful in the automotive sector for degreasing engine components - such as cylinder heads - before machining. It's used in processes that need a very clean environment, such as electronics companies and hard-disk manufacturers. For example, it can be used to remove solder flux from printed circuit boards after assembly.
