The Wetblasting Process

Vertical Tabs


The key to wetblasting is that the finish is produced through the flow of water borne abrasive. A finer finish is achieved due to the lubrication and flushing action of the water during the blasting process.

Dry grit and bead blasting processes are shown here in diagrams 1 and 2, which demonstrate the severe 90 degree ricochet that occurs when using these methods.

Diagram 3 shows the wetblasting method and how the cushioning from the water along with the altered angle for the media, produces a lapping effect which travels across the surface of the component being blasted. A satin/polished finish is the result, desired and preferred by many industries.

The wetblasting process is particularly effective for:

Cleaning of dies and moulds

Removal of pain, rust, scale, carbon and similar deposits

Surface preparation prior to bonding, re –painting and recoating

Satin finishing of stainless steel and other metals

Cleaning of PCBs and electrical components

Blasting in environments which must remain dust free

Advantages of wetblasting:

Dust free process

Cleans by flow and not impact

Simultaneously degreases and blasts

Produces a softer/smoother finish

The smoother finish makes the components more resilient to handling without leaving finger marks

Water acts as a lubricant between media and the component

Promotes longer media life

Avoids media impregnation on softer materials


Vixen's Aquablast® range of wet blasting machines ensures a superior finish at the end of the blasting process. These machines give you the perfect alternative to dry blasting, in what is a dust-free process with a softer surface finish, which in cosmetic applications, keeps components cleaner for longer. The Aquablast® range has 3 standard model sizes and custom build options.
