Bead Blasting

Bead blasting is a surface finishing process that involves propelling fine abrasive media, typically glass or ceramic beads, at high velocity onto the surface of a part using compressed air. This mechanical abrasion removes minor surface imperfections, tool marks, and contaminants, resulting in a uniform, matte, or satin-like texture. Unlike machining, bead blasting does not significantly alter dimensional tolerances, making it ideal for cosmetic enhancement without compromising part geometry. The process improves surface aesthetics and can enhance fatigue resistance by inducing compressive residual stresses on the surface. Surface roughness after bead blasting typically ranges from 2.5 to 3.5 µm Ra, depending on media size, pressure, and exposure time. It is commonly used onmetals likealuminum ,stainless steel , andtitanium to prepare surfaces for painting,anodizing or bonding. Bead blasting also reduces glare and reflectivity, making it suitable for optical and consumer-facing parts. The resulting finish is non-directional and consistent across complex geometries. Overall, bead blasting is an effective method for achieving both functional and aesthetic surface improvements.
