Surface Finishing
Surface Finishing
Aimed at various industrial applications, the Micro-Blast beads are widely used in the surface finishing of various ferrous and non-ferrous materials. Glass bead blasting prevents corrosion and enhances product performance while introducing compressive residual stresses at the surface.
Micro-Blast beads can be used for surface finishing, cleaning, deburring and shot peening. All surfaces can be treated: metal, plastic, glass, rubber…Beads are certified according to: MIL-STD-13165 – Military standard for shot peening of metals ISO 11124 & ISO 11125 – Metallic blast-cleaning abrasives (specifications & testing) EN 13744 – European standard for glass beads in blasting
Peening
Glass bead peening is an effective way of increasing the fatigue properties of metal parts and resistance to stress corrosion cracking. The Micro-Blast beads are hard and lightweight thus producing a high magnitude layer of residual compressive stress while leaving a smooth surface finish. Micro-Blast beads are a non-ferrous media and are readily used to peen non-ferrous metals such as aluminum and stainless steel. The beads are chemically inert, recyclable and environmentally friendly.
Blasting
premium spherical glass beads used as non-aggressive blasting media for cleaning, finishing, and surface preparation of metal and precision components.
Key Benefits
- Smooth stain surface finish
