Precision crafted, perfection in every piece！
Our Display Back Shell is a high-performance protective back cover designed for smartphones, tablets, monitors, and other electronic devices. Manufactured from advanced polymer composites or lightweight metals like 6061-T6 aluminum alloy, these back shells provide structural integrity while maintaining minimal weight (15–30 g for mobile devices). Modern designs incorporate EMI shielding (30–60 dB attenuation across 1–10 GHz), thermal management (3–5 W/mK conductivity), and precision tolerances (±0.1 mm) to ensure a perfect fit.
Polymer Option: High-grade PC-ABS blend with V-0 flame-retardant rating
Metal Option: Anodized aluminum with 500–600 HV hardness for superior scratch resistance
Lightweight yet durable, optimized for structural integrity and minimal bulk
Lightweight and Strong
Constructed from advanced polymer composites or 6061-T6 aluminum alloy, weighing only 15–30 g, with a rigidity improvement of 40–60%. Bending tests show deflection reduced from 2.5 mm to 1.0 mm.
Enhanced Thermal Management
Incorporates phase-change materials to lower peak temperatures by 8–12°C, with premium models using vapor chamber technology for thermal conductivity up to 10,000 W/mK, preventing overheating and extending component lifespan.
Effective EMI Shielding
Features multi-layer conductive coatings and Faraday cage structures that provide 30–60 dB EMI attenuation and reduce RF leakage by 85–90% at 2.4GHz and 5GHz, ensuring stable connectivity.
Versatile Applications
Suitable for consumer electronics (0.5 mm design, ≥75% wireless charging efficiency), industrial displays (IP67/IP69K compliance), automotive displays (UL94 V-0 rating), and medical equipment (silver-ion antimicrobial coating).
Low Maintenance and Durability
Easy to clean with isopropyl alcohol, featuring DLC coatings with 2,000–3,000 HV hardness and a low friction coefficient. Optional sacrificial coatings offer a 5-year recoat interval for extended wear resistance.
Precision and Customization
Maintains ±0.1 mm tolerance for a perfect fit with devices, with OEM/ODM support available for tailored solutions in bulk orders, meeting specific industry needs.
