I’VE NEVER HEARD OF VAPOUR BLASTING, IS THIS PROCESS NEW?
Cabinet Vapour Blasting is not a new process. The process was developed in the United Kingdom back in the 1940’s. It was originally used in the aircraft industry to treat items such as compressor impellers, turbine blades and fuel pump springs. After processing parts, imperfections and cracks were highlighted, and fatigue life and surface finish was considerably improved. Recently it has become a leader in the motorcycle and car restoration industry.
WHY IS VAPOUR BLASTING BETTER THAN THE MORE COMMON TYPES OF MEDIA BLASTING?
Conventional blasting methods embed abrasives into the metal and can create porosity on the surface. This condition attracts and holds dirt and grease, making it nearly impossible to clean once soiled. Aggressive, dry blasting may damage or erode the base metal.
Being a liquid process, the vapour blast flows into areas inaccessible by other methods. Threaded holes remain free of thread damaging abrasive particles, masking or plugging holes is not required. No heat is generated that may distort or damage parts. Vapour blasting is non abrasive and does not alter the dimensions of parts.
WHAT TYPE OF METAL IS BEST SUITED FOR VAPOUR BLASTING?
All metals are suitable for vapour blasting, some may need an anti-corrosive added to prevent flash rust. Vapour blasting is perfect for non-ferrous metals such as Aluminium, Brass, Bronze, Copper, Mild Steel and Stainless Steel. Vapour Blasting can also be used on Plastics and Carbon Fibre.
WHAT ARE SOME VAPOUR BLASTING APPLICATIONS ?
- Decarbonising
- Deflashing
- Decontamination
- Derusting
- Degreasing
- Peening
- Descaling
- Deburring
- Surface Preparation for bonding, polishing, welding or coating
Advantages of Vapour Blasting over Sand Blasting
WHAT IS THE DIFFERANCE BETWEEN VAPOUR BLASTING AND SAND BLASTING?
Vapour blasting removes coatings, corrosion, contaminants and residue from hard surfaces. It’s similar to sandblasting, except that the blast media is moistened prior to impacting the surface.
Vapour blasting works by expelling a slurry of media/water which is accelerated and atomised by pressurised air.
CAN YOU VAPOUR BLAST THE SAME MATERIALS AS SANDBLASTING?
Vapour Blasting can substitute for sand blasting in virtually any application. There are many surfaces, conditions and environments for which vapour blasting is far more advantageous than sandblasting.
DOES VAPOUR BLASTING LEAVE DEBRIS AND IMPERFECTIONS ON THE METALS?
Unlike sandblasting which can leave debris and dust everywhere, vapour blasting is a clean technique due to it being water based providing a dust free technique.
CAN PARTS BECOME WORN AWAY BY VAPOUR BLASTING?
No, this is highly unlikely. The way sandblasting works is by using abrasive force to clean and strip parts, taking some of the metal away with it. Vapour blasting is a non-abrasive method which cleans by flow of water, not impact. This ensures all the metal remains and part dimensions are preserved.
WILL MY PARTS LAST LONGER USING VAPOUR BLASTING TECHNIQUES
Yes, this technique is perfect to extend the life of your parts. Even after future treatments the part dimensions will stay the same, unlike sandblasting which will erode the part after each treatment.
WHICH TECHNIQUE IS BETTER FOR VINTAGE OR CLASSIC PARTS?
As vapour blasting uses a lower PSI than sandblasting, it can remove coatings without damaging the underlying surface. This makes it the perfect technique for vintage, classic, fragile and soft surfaces.
DOES VAPOUR BLASTING PROVIDE A BETTER FINISH THAN SANDBLASTING?
The water used in vapour blasting provides lubrication between the media and the component allowing a softer finish that avoids media impregnation of softer metals. The lubricating water also reduces heat due to friction which avoids warping of metal parts.
