Glass beads for shot blasting are a type of filler used for surface treatment technologies, primarily for cleaning and strengthening the surfaces of stainless steel and metal components. They effectively remove rust, coatings, oxide layers, and other contaminants from these surfaces.
glass beads for shot blasting
This blasting material is non-toxic, odorless, and consists of transparent or semi-transparent small spheres. Its mechanical and chemical properties are extremely stable, with outstanding wear resistance, making it particularly suitable for treating the surfaces of softer items. Glass beads are very light and perfectly sized, with excellent compressive and shock resistance, which gives them unique advantages in blasting applications.

Uses of Glass Bead Blasting Decoration and Aesthetic Enhancement:
- Glass beads can beautify and decorate soft surface items, achieving a semi-transparent or matte finish.
- Surface Treatment: They primarily remove oxide layers, old coatings, and rust stains, making the surface cleaner and more aesthetically pleasing with a high gloss.
- Increased Safety: Glass beads can remove burrs and sharp edges, preventing potential cuts or injuries during use.
- Cleaning and Stain Removal: They effectively clean oxidation, rust, stains, grease, and old coatings from surfaces, especially metals, glass, and plastics.
- Marking and Etching: By adjusting the bead size and parameters, glass beads can be used for surface engraving, serving as a means for marking and anti-counterfeiting.
- Due to these characteristics, glass beads are now widely used in industries such as automotive, construction, art, electronics, and home goods.
- When selecting glass beads, carefully choose the appropriate size to ensure the best blasting results.

When used for shot blasting, glass beads for shot blasting have the following characteristics:
1），Lightweight and Low Density: Glass beads are very light and have a low density.
2），Environmentally Friendly and Reusable: Glass beads are eco-friendly and can be recycled. Their wear rate is relatively low within a certain range, resulting in a longer service life.
3），Optimal Surface Treatment: Since glass beads are gentle, they do not leave any stains or slight scratches on the treated items, ensuring no damage to the surfaces.
4），Enhanced Safety: Glass beads do not easily generate sparks, reducing the risk of fire or explosions.
5），Appropriate Hardness: With just the right hardness, glass beads have a relatively small impact force on surfaces, minimizing potential damage.
6），Improved Surface Quality: glass beads for shot blasting can clean and enhance surface quality, improving brightness and wear resistance.
7），Uniform and Hard Particles: Glass beads have uniform and hard particles, allowing for fine surface treatment and meeting high surface finish requirements.
