What is Vapour Blasting?
The Vapour Blasting process is believed to have been developed by Rolls Royce in the 1940’s to clean precision turbine blades from jet engines.
Vapour Blasting is a non-aggressive cleaning process which only removes the dirt, contamination and corrosion, while simultaneously achieving cosmetic enhancement.
No material is eroded from the part, so all critical machined dimensions are maintained.
Vapour Blasting will not contaminate the part by embedding blast media into the surface as traditional sandblasting techniques are known to do .
The spherical glass bead used within the system is mixed with water to form a slurry and is accelerated at the component with the addition of compressed air at relatively LOW pressure.
The water cushions and lubricates the beads on impact allowing very fine finishes to be produced. The result is an attractive satin / semi-polished finish which is very easy to keep clean and will usually not show finger marks when handled.
It is most effective when performed on non-ferrous metals such as aluminum, brass, magnesium and copper , and will not damage these materials as traditional dry blasting methods can.
Vapour blasting is an economical alternative to traditional alloy polishing.
Ferrous metals including steel, stainless steel and cast iron may also be processed with excellent results.
The blasting slurry contains a rust inhibitor to prevent steel and cast iron from flash rusting upon removal from the machine.
Vapour Blasting is also known as HydroBlasting, VaquaBlasting, AquaBlasting and Wet Bead Blasting.
Disclaimer: Customer’s parts are flushed and rinsed with water, and dried with compressed air after the blasting process. Whilst every effort is made to ensure returned parts are free of blasting media, it remains the customer’s responsibility to check that the returned parts are suitably clean and decontaminated prior to use and/or re-assembly.
Vapour blasting is the best way to clean aluminium parts and castings.
