Features
1. Ultra-Precise Dimensional Accuracy (±0.05mm)
CNC machining ensures exceptional dimensional stability with tolerances as tight as ±0.05mm, guaranteeing perfect fitment with TV panels and internal components. This level of precision eliminates gaps and minimizes vibration transmission, critical for maintaining image stability in high-resolution displays.
2. Aerospace-Grade Aluminum Alloy (6061-T6 or 7075)
Manufactured from 6061-T6 or 7075 aluminum alloys, these covers achieve an optimal balance between strength and weight. With tensile strength ranging from 276-572 MPa and density of 2.7g/cm³, they provide robust protection while maintaining excellent heat dissipation properties (thermal conductivity of 167 W/m·K).
3. Optimized Thermal Management (20-30% Improved Heat Dissipation)
The machined design incorporates precisely calculated heat sink fins (typically 0.8-1.2mm thickness) and ventilation patterns that increase surface area by 35-45% compared to stamped metal covers. This engineering reduces operating temperatures by 8-12°C, significantly extending component lifespan.
4. EMI/RFI Shielding Effectiveness (60-80dB Attenuation)
The monolithic construction provides superior electromagnetic interference protection, achieving 60-80dB attenuation across frequencies from 10MHz to 6GHz. This exceeds industry standards for consumer electronics and prevents signal degradation in smart TV systems.
5. Surface Finish Options (Ra 0.4-3.2μm)
Available with multiple surface treatments including bead blasting (Ra 1.6-3.2μm), precision machining (Ra 0.8-1.6μm), or mirror polishing (Ra 0.4-0.8μm). Anodizing options provide 15-25μm oxide layers with hardness up to 60 Rockwell C for scratch resistance.
6. Structural Rigidity (3-5x Stiffer Than Stamped Steel)
The unibody construction achieves a stiffness-to-weight ratio 3-5 times greater than conventional stamped steel covers, with typical deflection under load measuring less than 0.3mm across 65" diagonal spans. Ribbed reinforcement patterns maintain this rigidity while reducing weight by 15-20%.
