Frequently Asked Questions
Q1: What material is used for the 5G base station cover?
We use high-quality ADC12 aluminum alloy. This material offers an optimal balance of structural strength, excellent corrosion resistance, and high thermal conductivity, making it ideal for outdoor base station applications.
Q2: How does the cover perform in harsh outdoor environments?
The cover features superior durability due to its high-quality aluminum construction and specialized powder spraying. It undergoes rigorous performance testing, including salt spray testing and alcohol resistance tests, to ensure long-term outdoor protection.
Q3: What thermal management features does the design include?
Aluminum has naturally high thermal conductivity. The cover's design facilitates efficient heat dissipation away from critical internal base station electronics, preventing overheating and ensuring stable signal transmission.
Q4: What quality control checks are performed during manufacturing?
We implement a comprehensive QC process including IPQC, IQC, FQC, and OQC. Inspections cover dimensional accuracy (checked via calipers, projection, and 3D systems), surface finish (Ra 0.8), thread compliance using go/no-go gauges, and 100% visual inspection of the powder coating.
Q5: How do you prevent deformation during shipping?
During the packaging step, products are handled gently and placed into custom knife cards. A protective layer of flat cardboard is placed on the upper layer before final boxing to prevent movement and physical damage during transit.
