FEATURES OF CERAMIC BEADS BLASTING MEDIA
Surface finish consistency
01 Low breakdown
With features of less abrasive breakdown and almost no dust
generation which in turn results in a cleaner working environment
and better operator visibility
Comparing with glass beads, ceramic bears is of low breakdown rates
up to 15:1 , thus enables it repeatable and consistent result to be
achieved.
02 Narrow particle size distribution
The more centralized granularity can make the objects surface more
uniform, and softer view in blasting process.

APPLICATION OF CERAMIC BEADS BLASTING MEDIA
1) 3C products - Sandblasting Finishing
Alloy shell, middle frame and built-in parts of computers, mobile
phones, cameras, etc. - sandblasting finishing
Clean burrs to form film-light decorative or fine reflective
surface, on alloy workpiece such as mobile phone to achieve
different reflection or matte.
2) Kitchen Industry-Sandblasting finishing
Stainless steel cutlery and kitchen utensils sandblasting finishing
3) Golf club - Sandblasting finishing
Golf club & ball head alloy surface treatment Sandblasting
finishing
4) Casting and forging parts, welded parts, heat-treated parts -
Sandblast Cleaning
Clean all the dirt on the surface of the alloy workpiece, micro
burrs, improve the flatness and smoothness of the workpiece, and
expose to uniform metallic color, achieving smooth and
non-reflective requirements on surface.
5) Pipeline - Sandblast Cleaning
Metal pipes such as copper pipes and steel pipes are cleaned and
polished on the inner and outer walls.
6) Molds - Sandblast cleaning
Cleaning of molds of glass bottles, tires, etc., rust, dirt and
impurities.
7) Electroplating, painting, anode-Surface Pretreatment
Electroplating, painting, anode, Teflon, rubber, plastic,
traversing, metal, spray welding, gold plating, titanium plating,
etc., to remove dirt and increase product surface adhesion.
8) Hardware parts - Sandblasting to improve lubrication conditions
It can produce uniform and fine uneven surface on the surface of
the part, so that the lubricating oil can be stored, improve the
lubrication condition and reduce the noise.
1) Aerospace industry-Shot Peening
Suitable for aerospace engine components, aircraft landing gear,
gear transmissions, aero-engine blades, aircraft wing-shot peening
2) Automotive industry-Sandblasting reinforcement/ Shot Peening
Suitable for gearbox gears, automotive aluminum hubs, piston
components/shock absorbers, engine crankshaft sandblasting
reinforcement/shot peening
3) Machinery, Medical Instrument - Sandblast finishing/shot peening
The overall sandblasting and polishing, finishing, restore the
natural color of the metal, enhance the visual effect and texture,
and also shot peening reinforcement to improve its worklife.
