Product Display
Features
With the rapid expansion of 5G technology, base stations are critical to ensure continuous connectivity and fast data transmission.
The product's exceptional durability is one of its main advantages. The cover is constructed from high-quality aluminum for superior strength and corrosion resistance, ensuring long-lasting performance even in the most demanding conditions.
The aluminum top is not only sturdy but also provides good heat control. Because the material has strong thermal conductivity, it can effectively dissipate heat, minimize overheating, and ensure that the base station operates at the highest efficiency.
Furthermore, the design of the lid is both elegant and functional. It has a sleek, modern style that blends easily into its surroundings, making it ideal for urban environments and public spaces.
Process
1
Aluminum die casting
Material: ADC12; Equipment: 1250T aluminum die-casting machine.
Process characteristics
- Material handle: 20±2mm, furnace temperature: 670°±20°
- The use of secondary items is not allowed
- Verify through testing that the material composition is suitable and can be manufactured
- After die casting, first piece confirmation is required
Preventive measures include
- Verify the filling quality of the surface. It’s not the bulge, it’s not the cold insulation, it’s not the lack of material in the pillars.
- Pay attention to the surface to prevent poor ejector pin crown, mold pulling or mold sticking.
- For non-machined surfaces and machined surfaces, the ejector pins are concave by 0-0.2 mm. The ejector pin must have a 0-0.2 mm convex shape.
2
Take out the nozzle (saw nozzle) and close the slag bag
Equipment: Wooden Stick/sawing machine
Note
- Pay attention to the surface and don't damage it or lack of material.
- Manage size and appearance.
3
IPQC inspection (verify detailed dimensions in drawings)
Testing instruments: calipers, projection, three-dimensional modeling, visual appearance inspection
Precautions
Check dimensions against drawings and use accurate measuring equipment.
4
Product back plastic surgery
Product anti-shaping tools: shaping jig, blade ruler
Caution
Within 0.25 mm from the front of the product.
5
CNC (Deburring + Full Material Inspection + CNC Processing)
Processing steps
-
A. CNC turning: Process the through hole of the perforation, the end face of the inner cavity and the surrounding heat dissipation tooth surface.
Tools: CNC machine tools, drill bits, tap processing fixtures, flat bottom milling cutters. -
B. Burr: To achieve a smooth appearance, the product's sharp corners are chamfered, deburred, and non-machined ejector pins are sharpened and polished.
Tools: sandpaper (120#), wind grinder, file. - C. Appearance visual assessment and 100% material inspection.
Precautions
- Avoid over-cutting or improper processing; Be careful not to produce burrs or damage the surface.
- Verify that the treated surface has Ra0.8 polish and dimensional and shape tolerances.
- The R corners should be connected smoothly, no burrs or sharp corners should be removed, and no processing should be missed.
- The surface of the product must be free of burrs, blisters, lack of material and other undesirable features.
- Use the go gauge and stop gauge to detect.
- Verify product flatness against design.
- To avoid deformation, please handle with care.

IPQC inspection
Appearance visual assessment
7
Polish (manual removal)
Slag bags, gate residue, surface particles and product clamping wire caps should all be removed.
Note
The mold closing line should be connected smoothly, no sharp edges or corners should be removed, and no processing should be skipped.

IPQC exam
Prepare for a rainy day
Appearance visual assessment
9
Area powder coating: outsourcing powder coating
Test Equipment: Appearance visual inspection combined with colorimeter, film thickness meter, salt spray tester, hundred grid tester, alcohol resistance test, pencil test
Precautions
- The painted and baked-proof fractal area is clearly visible;
- The color is consistent with the sample and the color is uniform;
- There is no abnormal color, dirt, exposed bottom, dust accumulation, scratches, etc.
10
IQC incoming material inspection and IPQC inspection
Inspection of appearance and unique qualities.
Note
- Verifying surface condition after powder coating;
- Randomly inspect/test holes using a pin gauge or a hole gauge.
11
Overall appearance + packaging inspection
Consumables: dividers, containers, bubble wrap and desiccant. Thoroughly inspect the goods and packaging.
Precautions
- Check the appearance based on the sample. There should be no dents, scratches or other blemishes on the surface and the glue application should be smooth and flawless!
- The pass and stop inspection requirements of the tooth profile must be met.
- After the product is inserted into the knife card, the top layer is covered with a flat cardboard and wrapped.
12
FQC exam
Testing instruments include: calipers, projectors, pin gauges, tooth gauges, outer packaging inspection, etc.
Note
Verify that the measurement device is still within its calibration window.
13
Transportation
Note
- Confirm that the quantity matches the order.
- Label and stamp the outer box.
- Send reports on shipments.
14
OQC shipment inspection
Inspection instruments: calipers, projectors, tooth gauges, needle gauges, appearance, outer packaging inspection.
Prepare for a rainy day
If the measuring device is still within its calibration window. Whether it meets both customer and SIP requirements.
Frequently Asked Questions (FAQ)
What materials and equipment are used to manufacture the 5G base station outdoor cover?
The cover is manufactured using high-quality ADC12 aluminum alloy. The production utilizes a heavy-duty 1250T aluminum die-casting machine to guarantee superior structural strength.
How does the aluminum cover manage heat dissipation for outdoor 5G base stations?
Aluminum features excellent thermal conductivity. During the CNC turning process, the end face of the inner cavity and the surrounding heat dissipation tooth surface are precisely machined to maximize thermal efficiency and prevent overheating.
What surface treatment is applied to the 5G base station cover?
The product undergoes an outsourced area powder coating process. The coating is strictly verified using advanced testing tools including a colorimeter, film thickness meter, salt spray tester, hundred grid tester, alcohol resistance test, and pencil test.
What quality control steps are taken during the CNC machining process?
We perform a 100% material inspection and visual assessment. Precautions include checking flatness, testing dimensional tolerances, verifying smooth connections of R corners, and utilizing go and stop gauges to ensure no burrs or defects exist.
How are the finished covers packaged to prevent transit damage?
Covers are thoroughly inspected for surface blemishes. They are inserted into knife cards, separated by protective dividers, wrapped in bubble wrap with desiccant, and covered with a flat cardboard layer to prevent scratches or dents during transportation.
