3 Key Technological Breakthroughs in 5G EMI Shielding Frame Molds

The rollout of 5G networks demands unprecedented precision in electromagnetic shielding. At GREATECH TOOLING, cutting-edge innovations in shielding frame molds ensure 99.99% effectiveness (SE) even at millimeter-wave frequencies (24–100 GHz). Here are three transformative breakthroughs powering next-gen 5G devices.  

1. Sub-Micron Laser Engraving (≤3μm Precision)
Traditional machining struggles with 5G’s high-frequency leakage risks. Our laser-engraved micro-cavity technology creates interlaced shielding grids with ≤3μm pitch， blocking interference up to 93 dB at 60 GHzverified by CETECOM testing.  

2. 16-Cavity Progressive Die Stamping
To meet explosive 5G demand, our patented multi-cavity system delivers:  
10,000 units/hour output (±5μm tolerance)  
37% lower cost vs. single-cavity molds  
Zero-defect stacking for 8-layer laminated steel  

3. Nano-Coated Hybrid Materials
Combining SUS301 stainless steel (0.15mm thickness) with proprietary Ni-Cu-Ag plating achieves:  
620 MPa tensile strength (vs. 350 MPa for conventional molds)  
<0.5Ω/sq surface resistivity  
Corrosion resistance for harsh outdoor deployments  

Why This Matters  
5G’s global expansion hinges on reliable EMI solutions. These advancements enable:  
✔ Faster rollout: High-yield production meets tight deadlines  
✔ Stricter compliance: Exceeds 3GPP Release 17 standards  
✔ Cost control: Material/energy savings slash TCO by 30%
