Core Advantages of Glass Bead Blasting
Core Advantages of Glass Bead Blasting
Compared to traditional blasting media (such as aluminum oxide or silicon carbide), glass beads offer the following irreplaceable advantages:
Precision Surface Control
Spherical particles: Avoid damage to substrates caused by sharp edges, making them especially suitable for soft metals (aluminum, copper) and precision components.
Uniform roughness: Achievable surface roughness (Ra) range of 0.1–5 μm (aluminum oxide blasting typically yields Ra > 2 μm).
Material Friendliness
Moderate hardness (Mohs 5.5–6.5): When softer than the substrate, they clean without cutting (e.g., steel with HRC > 20).
No embedded residue: Unlike steel grit or aluminum oxide, they leave no metal/ceramic particles behind.
Exceptional Cost Efficiency
Reusable 15–20 times (vs. aluminum oxide’s 3–5 cycles), with a wear rate of <5% per cycle.
50% lower overall costs: For example, in automotive wheel blasting, glass beads cost 1/3 that of steel grit.
Eco-Friendliness & Safety
No silicosis risk: Dust contains <0.1% free SiO₂ (compliant with OSHA standards).
100% recyclable: Spent glass beads can be remelted, producing zero solid waste.
Process Adaptability
Wide temperature range: Stable performance from -40°C to 300°C (special grades withstand up to 600°C).
Complex structure handling: Excellent flowability (angle of repose <30°), capable of cleaning deep holes with diameters as small as 0.3 mm.转成中文
