ROXOR Precision Blasting Systems
When the highest demands for reliability, longevity, and strength of thermally or mechanically stressed lightweight components must be met, surface treatment via shot peening is the most cost-effective solution. All relevant process parameters – including blasting media quantity, blasting pressure, nozzle movement, and workpiece handling – must operate within tight tolerances to ensure a reproducible blasting process.
Our processes are specifically developed for strengthening aerospace engine components. The distinction between methods is determined by the intended application.
