High Density 3.85g/cm3 Ceramic Beads Blasting media B30 425-600µm for Welded Steel assemblies
in Automotive Industries
1. Product Description of Cermaic Beads
Ceramic beads is one high efficiency and economical blasting media.
It selected the zircon sand as main raw materials by melting process in one electric furnace under high
temperature over 2000 degrees.
Ceramic beads has the characteristics of high hardness and good impact strength due to its microstructure.

4. Main Applications of Ceramic Beads
- In Sandblasting Applications:
Surface finish for metal and built-in parts of 3C products as well as its accessories;
Surface finish for stainless steel and light alloy
Surface Cleaning for various molds such glass bottle molds,die casting molds,tire molds,plastic molds...
Deburring for circuit board in electronics industires.
- In Shot Peening Applications:
Manufacturing and maintenance of titanium alloys components in areospace industries
Shot peening in automotive and turbine industries to improve the anti-fatigue life of shock absorber spring
and turbine blade...
5. Why ceramic bead is one popular blasting media?
Low break down rate and wear rate,which can be recycled repeatedly, finally reduce the energy consumption
and blasting cost;
High hardness and good elasticity,without damage to the surface of workpiece,eliminate the streess and
improve the fatigue life.
No ferrous and color contamination to the workpieces and blasting equipments.
Low dust generated in the whole blasting process,provide one clean working condition and ensure the
worker to escape from the hidden danger of silicosis;
High efficiency and provide more consistent blasting effect compared with glass beads.
6. The Advantages of Ceramic Beads compare with Glass Beads and Steel Beads
Ceramic beads has medium density,it can properly fill the upper and lower limits of the impact strength
between glass beads and steel beads;
Compared with the one of steel beads,ceramic beads will acheive the metallic color,there is no ferrous
contamination and metal powder residue on surface of the workpieces,non color cast phenomenon
compared with galss beads,ceramic beads will acheive higher finish and shinny visual effect.
