Aluminium Shielding & RF Shielded Enclosures (Die Casting)
DSW specialises in manufacturing high-precision aluminium shielding and RF shielded enclosures using advanced die casting technology.
Our aluminium shielding RF shielded enclosure is engineered to provide superior electromagnetic containment, structural protection, and thermal stability for high-frequency communication filters and RF assemblies.
This precision RF enclosure is designed for applications where shielding effectiveness, grounding continuity, and environmental durability directly influence signal integrity.
Manufacturing Technology
All enclosures are produced using high-pressure aluminium die casting, ensuring:
- Uniform wall thickness and structural rigidity
- Excellent repeatability for mass production
- Integrated mounting bosses and internal features
- Cost-efficient large-volume manufacturing
Material Specification
- Material: ADC-12 (AlSi12) aluminum alloy
- High electrical conductivity for aluminium shielding
- Good thermal conductivity for passive heat dissipation
- Strong corrosion resistance after surface treatment
Shielding Performance
- Die-cast aluminium structure provides natural RF attenuation
- Precision mating surfaces reduce seam leakage
- Optional conductive silicone EMI gasket
- Shielding effectiveness up to 80–100 dB (frequency and design dependent)
Optimized for UHF, VHF, sub-6 GHz, and microwave filter assemblies.
