What is Vapour Blasting ?
Vapor blasting, also known as wet blasting or liquid honing, is rapidly becoming the number one choice for applications requiring the highest quality of surface finish.
Wet blasting machines use the vapor blasting process to simultaneously degrease and blast industrial components, of many different shapes and sizes.
The key to vapor blasting is that the finish is produced through flow of water borne abrasive, giving a finer finish due to the flushing action of the water. No media is impregnated into the component, nor is there any dust created by the break-up of media, unlike dry blasting where the finish is produced by sheer force of media impact.
A specially designed glandless polyurethane pump agitates water and media into a slurry, which is contained within the cabinet sump. Delivery of the slurry to the manual blast nozzle is via a glandless polyurethane pump and associated hoses located inside the machine. The slurry is pumped at approximately 2 bar to the nozzle, and compressed air is introduced at the blast nozzle to accelerate the slurry and provide the cleaning effect on impact, albeit cushioned.
After contact with the component the slurry then drains back into the sump creating a re-circulating system. Fine broken down media and other contaminants are fed via an overflow to a sedimentation filter located at the rear of the cabinet.
The illustrations below show the different natures of grit, bead, and vapor blasting.
The aggressiveness of dry grit and bead blasting are shown in the first two illustrations which demonstrate the severe 90° ricochet that occurs when using these methods.
The third illustration shows the gentler, but just as effective, vapor blasting method. The ricochet of media is reduced due to the cushioning from the water; the angle of the media is changed producing a lapping effect travelling across the surface, giving an even satin/polished finish.
Advantages of Vapor Blasting
- Dust free process
- Cleans by flow of water not by impact
- Simultaneously degrease & blast clean
- Water acts as a lubricant between media & component
- Promotes longer media life
- Produces a 'softer' finish
- Avoids media impregnation on soft materials
- Degreasing / surface finishing of components in the automotive, reconditioning & maintenance industries
- Cleaning of dies & moulds
- Removal of paint, rust, scale, carbon & similar deposits in engineering industries
- Surface preparation prior to bonding, re-painting or re-coating
- Satin finishing of stainless steels & other special materials
- Cleaning of PCB's & electrical connectors
- Removal of small burrs from manufactured components
