How Electromagnetic Shielding Frame Molds Ensure 5G Device Safety

Introduction  
The rollout of 5G networks has revolutionized connectivity, but it also brings unprecedented challenges: millimeter-wave frequencies (24-100 GHz) require electromagnetic shielding effectiveness (SE) exceeding 90dB to prevent signal interference. At Zhongshan Ruilifeng Mold Technology, our nano-precision electromagnetic shielding frame molds are engineered to meet these demands, ensuring 5G devices operate safely and reliably.  

1. Why 5G Demands Ultra-Strict Shielding Standards
High-Frequency Vulnerability: 5G signals above 6 GHz are 10x more susceptible to EMI (Electromagnetic Interference) than 4G.  
Miniaturization Challenges: 5G base station components require shielding frames as thin as 0.2mm while maintaining structural integrity.  
Regulatory Compliance: IEC 61000-4-21 standards mandate 360° shielding for devices operating in dense urban environments.  

2. Achieving 99.99% Shielding Efficiency with Nano-Level Precision
Greatech’s breakthrough lies in our sub-micron machining capabilities:  
Laser-Engraved Micro Cavities: Creates interlaced shielding grids with ≤3μm pitch, blocking GHz-range EMI.  
Multi-Layer Coating: Proprietary Ni-Cu-Ag plating enhances conductivity (＜0.5Ω/sq) and corrosion resistance.  
Real-World Validation: Third-party testing at CETECOM Labs confirms 99.99% SE across 6-60 GHz bands.  

Technical Highlight:    
| Frequency Band | SE (Industry Avg.) | SE (Greatech-tool) |  
|----------------|--------------------|----------------|  
| 6-24 GHz       | 85 dB              | 93 dB          |  
| 28-39 GHz      | 78 dB              | 91 dB          |  
| 60 GHz         | 65 dB              | 89 dB          |   

3. Multi-Cavity Synchronized Stamping: Revolutionizing 5G Base Station Production 
Our patented 16-Cavity Progressive Die System delivers:  
10,000 Units/Hour: Mass production capability for 5G AAU (Active Antenna Unit) enclosures.  
Zero Tolerance Stacking: ±5μm dimensional accuracy across 8-layer laminated steel sheets.  
Case Study: Reduced production costs by 37% for a leading European telecom equipment manufacturer.  
4. Material Innovation: Thinner, Stronger, Smarter

| Parameter       | Traditional Molds | Greatech Molds |  
|-----------------|-------------------|-----------------|  
| Material Thickness | 0.5mm          | 0.15-0.25mm     |  
| Tensile Strength | 350 MPa          | 620 MPa         |  
| Surface Finish   | Ra 0.8μm         | Ra 0.1μm        |  

Explanation: Ultra-thin SUS301 stainless steel combined with Greatech’s asymmetric drawing process prevents micro-cracks during high-speed stamping.
