Industrial Glass Beads & Sand

1. Product Overview

Shiyan Technology’s Industrial Glass Beads are manufactured from high-quality soda-lime glass. They are processed into perfectly spherical shapes for high-precision sandblasting and surface finishing applications. Specifically, these beads are ideal for cleaning, finishing, and peening metal surfaces without removing the base material or causing dimensional changes.

2. Why Choose Shiyan Industrial Glass Media?

• High Roundness & Smooth Surface: Our glass beads feature a roundness rate of $\ge 85\mathrm{\%}$≥85%. Consequently, they deliver a consistent matte finish and effectively reduce stress on the workpiece.
• Chemical Stability (No Contamination): Made from lead-free, soda-lime glass, they are chemically inert. Therefore, they will not cause rust or iron contamination on sensitive aluminum or stainless steel parts.
• Consistent Grading: We utilize strict sieving technology to ensure uniform particle distribution. Moreover, this guarantees a predictable and repeatable surface texture for high-volume production.
• Cost-Effective Solution: While Zirconia beads offer longer life, our glass beads provide the most economical solution for one-time or medium-cycle blasting tasks.

3. Core Industrial Applications

• Surface Cleaning: Removing oxidation, scale, and carbon deposits from molds, engine parts, and turbine blades.
• Matte Finishing (Fogging): Achieving a decorative, non-glare satin finish on stainless steel cutlery, medical instruments, and decorative hardware.
• Stress Relief (Peening): Enhancing the fatigue life of automotive gears, springs, and aircraft structural components.
• Pre-Treatment: Creating an ideal surface roughness for subsequent coating, plating, or painting processes.
