Glass bead blasting is a process in which small glass beads are blasted onto a surface at high speed in order to clean or refine it. It is particularly gentle and results in a matt or silky lustre surface without removing much of the material.

The process is often used to clean metals such as stainless steel and aluminium to remove welding discolouration, impurities and machining marks. It is also suitable for decorative surface treatments and for preparing surfaces for further coatings.

Gentle material removal: It removes dirt and surface defects without damaging the base material.

Versatility: It can be used on a variety of materials, including metals, plastics and glass.

Recyclability: Glass beads can be used multiple times, making the process cost-effective and environmentally friendly.

Limited sanding effect: The process is less suitable for heavy material removal.

Sensitivity to moisture: Oxidation may occur in humid environments.

Necessary control: If used incorrectly, the glass beads can clump together and damage the surface.

Glass bead blasting is gentler than sandblasting and is more suitable for sensitive surfaces. Compared to dry ice blasting, it offers mechanical cleaning, whereas dry ice blasting relies on thermal effects. In contrast to steel blasting, it is less abrasive and does not produce metal chips.

Glass bead blasting is used in many industries, including the automotive, aerospace, medical technology and food industries. It is ideal for applications that require a clean and even surface, such as in preparation for galvanising or to prevent corrosion.

The choice of grit depends on the application. Fine grits are used for a smooth surface and fine details, while larger grits are used for more aggressive applications where a more pronounced surface change is desired.
