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.
