Ceramic beads

Ceramic beads are made from an extremely tough zirconium oxide ceramic. They are iron-free and are therefore suitable for use with stainless steel and aluminium. The round shape of the ceramic beads means that they can be used for non-aggressive cleaning and for producing visually attractive surfaces. This blasting medium has a very long service life when compared with glass beads. Ceramic beads are a high-tech blasting medium that meets the very highest standards.

Blasting systems

– Pressure blast systems
– Injection blast cabinets

Applications

Blast-cleaning:
– Removing mould residues from castings
– Removing tempering colour

Surface finishing:
– Finishing surfaces
– Creating visual effects
– Achieving a consistent surface roughness over the whole of the component being blasted

Shot peening:
– Compression of the surface
(strengthening the surface and improving its mechanical properties)

Shot peen forming:
– Shot peening to form or straighten workpieces
