Features
As the demand for high-speed data transmission increases, thermal management becomes critical to ensure optimal performance of 4G networks. Our housings effectively dissipate heat, reducing overheating and ensuring smooth operation of the base station.
This is especially important for exterior installations, where equipment can be damaged by exposure to the elements. Our housings are engineered to withstand weather conditions, prevent corrosion and extend the life of your base station.
Lightweight, easy to manage and easy to set up. This is a big benefit, especially when setting up base stations in hard-to-reach places. The lightweight design reduces shipping costs while also making installation easier.
Process

Frequently Asked Questions
The enclosure is manufactured using high-precision 400T aluminum die casting machines with premium ADC12 aluminum alloy material. This combination ensures high structural durability and excellent thermal conductivity.
The design features integrated heat dissipation copper bars (such as the SE4450 copper bars assembly) and peripheral heat dissipation teeth, processed via precision CNC to ensure maximum surface contact and optimal thermal management for 4G AAU base stations.
Yes. The enclosure undergoes specialized outsourcing surface treatments, combining powder spraying and oil spraying. It is thoroughly tested for corrosion resistance, salt spray, alcohol resistance, and general weatherability to ensure a long outdoor service life.
We maintain strict dimensional control. The front accuracy of the product is kept within 0.25 mm, and the processed surface finish is controlled to reach Ra 0.8. All tooth shapes and holes are verified using precise pass/stop gauges.
We implement a comprehensive multi-stage quality control system. This includes initial die-casting confirmation, multiple IPQC inspections, 100% appearance checks after powder coating, FQC inspections, and final OQC shipping checks using calibrated calipers, projectors, and gauges.
