ULTRASONIC CLEANING

The Process:

The process of Ultrasonic Cleaning utilises high frequency sound waves which are radiated through a liquid medium – As sound waves pass through the fluid microscopic bubbles form. These bubbles continue to grow in size until they become unstable and cannot support their own density causing them to implode – this is a phenomenon known as cavitation. As these bubbles collapse the surrounding cleaning fluid rushes in to fill the gaps, which creates an action similar to that of a scrubbing brush, but thousands of times per second per cubic centimetre. It is this process which gives ultrasonic’s its powerful cleaning action and makes it the most effective method of removing contaminates from substrates or complex shapes. This process can be further intensified by adding cleaning detergent to the liquid. Older engines are prone to carbon build up which reduces the air flow through the engine and can cause running problems. However, there is a method of cleaning available that uses no harsh solvents, is fast and effective and requires only minimal amount of effort.

Benefits:

Perfect for carburetters, injectors and brake components
Cleans all internals including jets and oil ways
Will clean areas that are otherwise impossible to clean
Non aggressive or erosive

In Layman’s terms; if an item is submerged within the cleaning liquid any surface area which is in contact with the liquid medium will be exposed to cavitation, and therefore the cleaning action.

Ultrasonic cleaning represents a number of benefits over alternative methods which are available. People are being urged to move away from traditional methods which use solvents to remove baked on deposits as these are both hazardous to the environment and can be dangerous to those using them. Solvent based systems also take longer to remove deposits with items often needed to be soaked in the solution for a long period of time in order to brake-down the baked-on carbon and fuel residues.

Our service:

On arrival your components will be disassembled (where required) and flushed of any major contamination. We then mix the right solution for your items based on components requirements. The items are then placed in the ultrasonic cleaning tank. Once the items are cleaned they will be reassembled to your requirements!
