Grinding and Shot Blasting Glass Beads for Surface Treatment
SEPPE Grinding and Shot Blasting Glass Beads for Surface Treatment are selected spherical glass beads for blasting, grinding-assisted finishing, peening and surface preparation. Suitable particle size can be selected according to the workpiece, required surface roughness and blasting equipment, making it suitable for efficient cleaning, visible matte finishing and controlled surface treatment without the aggressive cutting profile of angular abrasives.
Product: Glass beads for grinding-assisted finishing, shot blasting and surface treatment
Model: Customized blasting particle size
Other Names: Shot Blasting Glass Beads, Surface Treatment Glass Beads, Glass Bead Blasting Media
Material Type: Soda-lime glass spherical media
Manufacturer of Material: SEPPE TECHNOLOGIES
• This product is a coarse glass bead blasting media designed for surface treatment applications where stronger impact and stable spherical shape are important.
• The selected blasting grade helps remove light contamination, smooth burrs and create a uniform matte finish while reducing deep scratches compared with angular abrasive grains.
• It can be used in blasting cabinets, pressure blasting systems and selected surface finishing processes according to equipment setup and workpiece requirements.
• Application-matched Particle Size: Coarser or finer particle size can be selected according to cleaning strength and finish requirements.
• Spherical Blasting Action: Round particles clean mainly by impact, helping avoid excessive cutting into the base material.
• Stable Surface Appearance: Uniform particle size and smooth bead surface help maintain consistent matte finishing results.
• Good Flowability: Clean glass beads support stable feeding and circulation in blasting equipment.
• Reusable Blasting Media: Suitable toughness and hardness support repeated use under controlled pressure conditions.
| Application Need | Recommended Grade | Typical Result |
|---|---|---|
| Stronger impact cleaning | Coarser blasting grade | More impact energy for practical surface treatment |
| Matte finish on metal parts | Medium blasting grade | Uniform satin surface with reduced cutting marks |
| Shot blasting cabinet use | Equipment-matched grade | Good media flow and visible cleaning effect |
| Peening and stress relief | Application-matched grade | Controlled round-particle impact for selected components |

• Selected glass raw material - melting - bead forming - cooling - cleaning - screening and classification - roundness and appearance review - packaging.
• The process is designed to control particle size distribution, roundness, bubble content, impurities and surface smoothness for stable product performance.
• Particle size distribution is checked by sieve analysis according to ordered mesh grade.
• Roundness, broken particles, bubbles, visual cleanliness and surface smoothness are reviewed by batch.
• Physical properties such as bulk density, hardness reference and crush rate can be checked according to purchase specification.
• Batch COA, particle size report, retained sample support and third-party inspection can be arranged according to order requirements.
• Common packaging includes 25 kg bags, 1000 kg jumbo bags, palletized bags and customized export packaging. Bag marks and pallet protection can be arranged according to purchase requirements.
• Store glass beads in dry conditions and protect bags from moisture, contamination and package damage before use.
• Loading photos, batch labels and inspection records are available to support shipment traceability.
• They are commonly used for shot blasting, surface treatment, matte finishing, burr removal and cleaning of metal parts.
• Coarser grades provide stronger impact, while finer grades produce a more delicate finish. Final selection should follow workpiece material, equipment and required surface effect.
• Glass beads are spherical and work mainly by impact, so they generally create smoother finishes than angular abrasives under proper blasting conditions.
• Yes. It can be used in suitable pressure blasting or cabinet blasting systems. Final settings should be adjusted according to the workpiece and finish requirement.
