1. Product Overview (High-End 3C Special)
Shiyan Technology’s SY-YZ & SY-B Series Zirconia Ceramic Blasting Beads (commonly known as Apple Sand) are specifically engineered for premium smartphone, laptop, and PAD shell surface treatment. Utilizing an advanced Titration Process and 6nm hydrothermal zirconia powder, our beads provide a uniform, high-end matte finish that is the standard for top-tier electronics.
2. Why Shiyan Apple Sand is Superior?
- Perfect Spherical Precision: Each bead is formed independently via titration, ensuring a flawless round surface. Specifically, this prevents micro-scratches on sensitive magnesium-aluminum and titanium alloy frames.
- Extreme Durability & Low Breakage: With a density of 6.05 g/cm³, our beads last 20-30 times longer than traditional glass beads. Consequently, they significantly reduce dust pollution and operational costs.
- No Metal Contamination: Our zirconia beads are chemically inert. Therefore, they do not leave iron residue, preventing surface oxidation or discoloration after anodizing.
- Superior Satin Finish: Designed to achieve a precise matte/fogging effect that is smooth to the touch, matching the aesthetic requirements of global tech giants.
3. Core Applications (High-Performance Solutions)
- Smartphones & PADs: Finishing for mid-frames and back covers (Aluminum, Stainless Steel, Titanium).
- Medical Devices: Surface cleaning and stress relief for titanium implants and precision surgical tools.
- Aerospace Components: High-precision shot peening for engine blades and critical landing gear parts.
- Automotive Parts: Surface fogging for high-end interior trims and lightweight alloy components.
