How Wet Blasting Works:
How wet blasting, also known as slurry blasting,
wet etching, liquid abrasive blasting, and wet honing works:
You’ve mixed water with abrasive before. Think of pumice
hand soap. The action is scrubbing. It works better than washing
with just soap. Think parts washers.
Wet Technologies mixes abrasives and non
abrasive medias such as glass and ceramic beads, and even
plastics, with water. This is done with our own special, high
volume, low maintenance pump in a closed loop stainless steel
cabinet. The slurry is then discharged at a controlled and
regulated velocity by nozzle(s) or other means at the part
Unlike dry blasting or sand blasting, Wet
Technologies wet blasting uses high volume water in the slurry
to cushion the media. This mostly eliminates media imbedded
into the surface.
are some examples of what the wet blasting can do when using:
ROUND MEDIA such as glass bead, ceramic, and
metal shot. These slurries are used to clean, smooth, brighten,
peen, and descale surfaces. Fine glass and ceramic slurries
can also deburr some parts. Ceramic and metal shot slurries
have longer life. When the slurry is heated, parts can be
cleaned of light oils and scale, while leaving a bright or
matt cosmetic finish. Applications range from aircraft component
“N scale” wet peen, or wet peening, to aviation
engine, landing gear, and automotive engine rebuilding.
ANGULAR GRIT MEDIA such as aluminum oxide, crushed
glass, and steel grit. These slurries are used for aggressiveness.
New machined components in the aircraft, automotive, marine,
and semiconductor segments can be deburred. Coarse grit sizes
are useful in engine rebuilding. Wet blasting with a coarse
grit can remove heavy scale or descale, remove rust or derust,
and at the same time remove light soiled oils or degrease
FINE ANGULAR ALUMINUM OXIDE slurry can deep
clean into the pores of surfaces. In the aircraft industry,
Wet Technologies applications include deep cleaning new and
used jet engine components to expose cracks, thereby making
then accesable for liquid penetrate inspection or LPI. When
composites are subject to wet blasting, wet etching leaves
an even, clean, and abraded finish with fewer high peaks and
low valleys than conventional dry blasting. The result is
less resin is required to fill the voids, leading to remarkably
strong bonding strength.
PLASTIC ANGULAR MEDIA slurry is used for removing
flash or deflashing plastic parts, and paint stripping. The
advantage: Wet Technologies systems can blast, closed loop
rinse, and dry parts in one contained cabinet. Our closed
loop rinsing and drying pass milipore testing, eliminating
the need for several conventional machines.
