Vapor blasting, sometimes called wet blasting or liquid honing, is rapidly becoming the go to service for applications that require a high quality surface finish.
Mid Valley Industrial Services uses the vapor blasting process to simultaneously degrease and blast away industrial components.
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.
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
