🔧 D-sub Metal Hood Engineering | Precision Die-Casting + EMI Shielding Performance
At WoYang Technology, our D-sub metal hoods continue to be one of the most reliable shielding solutions for industrial and communication systems.
Over the years, we have refined our tooling and die-casting process to achieve stable quality for demanding environments such as:
✔ Industrial automation
✔ Measurement instruments
✔ Railway & transportation
✔ Communication equipment
✔ Data transmission modules
🛠 Key Engineering Advantages
1. High-Pressure Zinc Die-Casting (Zamak 3 / Zamak 5)
Our housings are produced using high-pressure die-casting molds, ensuring:
• excellent rigidity
• consistent wall-thickness
• high dimensional accuracy (±0.03–0.05 mm)
2. EMI / RFI Shielding Stability
The metal hood provides reliable grounding and shielding performance, and is commonly paired with:
• nickel plating
• tin plating
• chromium plating
to meet different EMC requirements.
3. Multiple Cable Entry Designs
Our hoods support:
• straight exit
• 45° angled
• 90° angled
• large-cable versions for over-molded cables
4. Screw / Locking System Options
To match different equipment installation needs, we offer:
• 4-40 UNC screws
• M2.6 screws
• slide-locking system
• captive screws
5. Customization for OEM Projects
For customers requiring brand identity or specific mechanical adaptation, we support:
• custom logo engraving
• cable clamp redesign
• color finishing
• mechanical structure modification
If you’re working with D-sub connectors or need custom metal housings with high consistency, feel free to reach out.
We’re ready to support your next project.
