#7 Glass Beads – 10 lb (HDURCIR)
Beads sized for medium-grade finishing in blast cabinets or with blasting guns. The 120 grit size provides balanced material removal with a smoother final surface. Best for general deburring and surface prep on thin-walled parts where tight tolerances matter. The listed features emphasize cost efficiency by choosing larger packaging. This makes it suitable for small to mid-size shops that prioritize steady bead supply without frequent repurchase.
Who it’s best for: shops needing consistent medium grit finish on metal parts without redox risk or ferrous contamination. Why selected: reliable medium abrasion and cost-effective packaging options support routine blasting tasks. Caution: ensure proper ventilation and wear protection; glass beads can still create fine dust during blasting.
#12 Glass Beads – Extra Fine 140-230 Mesh
These extra-fine beads target delicate cleaning and pre-finishing tasks. The 140-230 mesh size is ideal for pre-polish work that preserves critical tolerances while removing micro burrs and surface contaminants. They are suitable for metal parts where precision is essential and ferrous pollutants should not be introduced. The product supports smoother finishes and sealable surfaces after treatment.
Who it’s best for: manufacturers and restoration specialists needing gentle surface prep on intricate components. Why selected: fine mesh helps clean surfaces without altering dimensions. Caution: the finer the bead, the less material removal per pass; expect more passes for deeper cleaning.
Blast Media, Glass Beads, Medium (BALLOTINI)
This medium-grade blasting media is designed to minimize material removal while delivering a smooth, clean finish. The round shape helps reduce gouging and is suitable for close tolerance work. It can be used wet or dry for deburring, cleaning, peening, finishing, and polishing, making it versatile for mixed-material components.
Who it’s best for: operations requiring careful finishing on thin-walled parts or assemblies with tight tolerances. Why selected: balance between material removal and surface quality. Caution: wet blasting requires appropriate equipment setup to avoid corrosion or residue transfer.
#10 Glass Beads – 10 lb (HDURCIR)
Medium-grade glass beads sized for broad blasting tasks. The 100-170 mesh range suits general finishing, deburring, and surface prep on a variety of metals and plastics. The packaging size supports steady use in busy setups. It is a reliable option for routine cabinet blasting where a balanced finish is desired.
Who it’s best for: shops needing a reliable all-around medium finish for diverse projects. Why selected: straightforward performance and consistent surface outcomes. Caution: is not ideal for ultra-fine finishing or very delicate geometries that require finer abrasives.
Glass Bead #13 Ultra-Fine (Winona Van Norman)
The ultra-fine 170-325 mesh beads are designed for matte finishes and defect blending on complex shapes. They are well-suited for metal cleaning, polishing, and deburring without aggressive material removal. The beads work on stainless steel, brass, aluminum, and plastics, and can be used on a range of die-cast components.
Who it’s best for: operations requiring delicate finishing on complex geometries where preserving feature dimensions is critical. Why selected: superior surface refinement and compatibility with sensitive alloys. Caution: ultra-fine beads can require longer processing times to achieve the desired level of polishing or defect reduction.
Buying Guide: Key Purchase Considerations
- Bead size and grit: Choose based on the desired material removal rate and surface finish. Coarser beads remove more material; finer beads yield smoother surfaces and less material removal.
- Part geometry and tolerances: Complex shapes and tight tolerances may benefit from finer beads or specialized media to avoid dimensional changes.
- Wet vs dry blasting: Wet blasting can reduce dust and improve surface quality but requires proper handling of moisture and residue.
- Equipment compatibility: Ensure the bead size matches your blast cabinet or gun orifice to maintain consistent flow and avoid clogging.
- Packaging and cost: Larger packaging often lowers per-unit cost, but ensure you have storage space and usage rate to prevent waste.
- Environmental and safety considerations: Glass beads are generally inert, but follow all PPE recommendations and ventilation guidelines when blasting.
Frequently Asked Questions
- What is the difference between fine and medium glass beads? Fine beads (higher mesh numbers) produce smoother finishes with less material removal, while medium beads offer a balanced finish and faster cleaning.
- Can glass beads be used on plastic parts? Yes, glass beads are versatile and can be used on many plastics, but test on a small area to verify finish and avoid surface damage.
- Is wet blasting necessary for glass beads? Not strictly, but wet blasting can reduce dust and help with surface finishing in some applications.
- How do I choose the right bead for tolerances? Consider the bead size and the part geometry; finer beads are often better for close tolerances, while coarser beads can achieve faster cleaning on larger areas.
- Are glass beads environmentally safe? Glass beads are generally considered environmentally safe when used according to standard blasting practices and PPE guidelines.
- What maintenance is needed for blasting equipment using glass beads? Regularly check hoses, nozzles, and the cabinet interior for wear and residue buildup; clean feeders to prevent clogs.
