Aluminum alloy die-casting parts offer a high strength-to-weight ratio, significantly reducing the weight of telecom equipment and lowering support structure costs​. Additionally, aluminum’s excellent EMI/RFI shielding properties ensure signal stability, and its outstanding thermal conductivity aids in efficient heat dissipation​.

Typical alloy grades include A380, ADC12, and A356, with A380 being the preferred choice for telecom cabinets and radomes due to its balanced mechanical properties, machinability, and excellent corrosion resistance​. For outdoor high-power modules requiring enhanced strength and thermal resistance, Al-Si-Cu series alloys are also used​.

Mold design should optimize the runner system, vents, and parting lines to ensure uniform melt flow and minimize defects such as porosity and cold shuts​. Additionally, appropriately specifying draft angles and fillets based on wall thickness distribution enhances mold durability and simplifies demolding​.

Aluminum alloy die-cast parts inherently provide excellent EMI/RFI shielding, effectively attenuating high-frequency interference to meet stringent telecom requirements. Enclosures made from ADC-12 alloy can achieve at least 60 dB shielding effectiveness through inherent metal thickness and surface finishing, ensuring signal stability and minimal crosstalk.

For outdoor base station cabinets and radomes, using high-silicon alloys, optimizing anodizing processes, and applying post-anodize sealing treatments create dense oxide films that greatly improve resistance to salt spray and acid rain. Industry reports indicate these measures can extend corrosion resistance by 2–3.

Custom die-cast enclosures can include built-in PCB support features and thermal channels, followed by CNC-machining of heat-sink fins. CastMold’s IP67 outdoor boxes integrate fins directly into the die-cast body with thermal interface materials, achieving a low thermal resistance of up to 30 W/K for efficient heat dissipation

Using 3D printing or soft tooling for prototypes to validate structure and fit, followed by production-grade steel molds based on finalized designs, can reduce time-to-volume by over 30%. CastMold offers such proto-to-production services, balancing development speed with manufacturing readiness
