Product Detail

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
Step 01
Aluminum die casting

Material: AlSi10MnMg/DX17

Equipment: 800T aluminum die-casting machine

Process characteristics:

a. Material handle: 20±2mm, furnace temperature: 670°±20°;
b. The use of secondary items is not allowed;
c. Verify through testing that the material composition is suitable and can be manufactured;
d. After die casting, first piece confirmation is required.
Preventive measures:
a. 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.
b. Pay attention to the surface to prevent poor ejector pin crown, mold pulling or mold sticking.
c. 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.
Step 02
Take out the nozzle (saw nozzle) and close the slag bag

Equipment: Wooden Stick/sawing machine/plastic cardboard/laminates/ gloves

Note:
a. Pay attention to the surface and don't damage it or lack of material.
b. Manage size and appearance
Step 03
Deburring

Removal of the fringe at the peripheral mold line and the inserts on the heat sink teeth. Remove the residue of side gates and slag ports, and remove the fringe at the ejector pin position.

Equipment: wind grinder, 120# sandpaper

Note:
a. The product shall not be non-sanded areas and fonts missing, playing collapsed edges, poking.
b. The product shall not have residual phi, shall not miss the phi, particles.
c. If bad or other emergencies occur in a timely manner, isolate and immediately report to the superior to deal with.
d. Pay attention to the transportation and processing process, hold and put the product lightly, do not bump the lack of, hit the deformation.
e. Hang the hangtag and product identification on the top of the cardboard, QC signature OK before transferring to the next process.
Step 04
IPQC inspection

Testing instruments: calipers, projection, three-dimensional modeling, visual appearance inspection

Precautions:
Use measuring tools correctly and check dimensions according to drawings.
Step 05
Product back shaping

Equipment: Cutting edge ruler, shaping tooling, hydraulic presses

Caution:
Within 0.3 mm from the front of the product
Step 06
IPQC inspection

Visual inspection of appearance

Step 07
CNC

Machining of internal cavity end faces, Backside holes, Side of one end, Hole through-hole

Equipment: CNC machine, flat-bottomed gong tool, Drill Bit, Tap machining jig.

Precautions:
a. Do not overcut, missed processing;
b. Surface attention must not be bruised, burrs; and
c. Ensure that the surface finish Ra1.6 size, shape and location tolerances
Step 08
Air tightness testing

Test pressure value in 20kpa ~ 30kpa, stabilized pressure 10 seconds, test time 10 seconds, leakage control within 0.3kpa

Equipment: Airtight Tooling, Airtightness Test Equipment

Precautions:
a. Do a good job on the product appearance surface protection, sealing groove parts without implementation of touch scratch;
b. Discover the phenomenon of air leakage in time to pick out the marking.
Step 09
100% material inspection

Visual inspection of appearance

Precautions:
a. The surface of the product should not be overcut, sand holes, lack of material. Burrs, and other undesirable phenomena
b. go-no go fixed gauges inspection
c. Test the flatness of the product according to the drawing.
d. Hold the product lightly to prevent deformation.
Step 10
Grinding

Chamfering R-angle, deburring, thimble shaving on non-machined surfaces, polishing and smoothing the shape.

Equipment: Air grinder, 120# sandpaper

Note:
Do not miss the processing, no sharp corners, burrs removed cleanly, connected to the R angle of the smooth.
Step 11
IPQC inspection

Visual inspection of appearance

Step 12
Cleaning + Chemical conversion membrane + power spraying
Note:
a. No different colors, dirty, not touching and scratching;
b. Color according to the sample, uniform and consistent;
c. Powder thickness is uniform, no accumulation of tumors, no exposed bottom.
Step 13
IPQC inspection + Special Characteristics Inspection

Visual inspection of appearance

Note:
a. Surface quality confirmation after chemical conversion membrane/power spraying;
b. Hole need to needle gauge sampling, go -no go fixed gauges inspection
Step 14
Riveting and pressing D4.7 dowels

Equipment: Pressure riveting jig, hydraulic press

Precautions:
a. Check that the pins are loaded without deviation or falling off, and that there is no bulge or pressure injury on the surface of the product;
b. Check the height dimension after pressure riveting;
c. glue glue the right amount to ensure that no spillage after loading to the pin hole.
Step 15
Full inspection + packaging

Thoroughly inspect the goods and packaging

Consumables: dividers, containers, bubble wrap and desiccant

Precautions:
a. The appearance shall be inspected according to the sample. The surface shall be free of dirt, scratches, dents and defects, and the glue dispensing shall be even and without defects!
b. The tooth pattern must comply with the go – no go fixed gauge inspection;
c. The product is placed in the knife card, and then packaged.
Step 16
FQC exam

Testing instruments: calipers, projectors, pin gauges, tooth gauges, outer packaging inspection, etc.

Note:
Verify that the measurement device is still within its calibration window.
Step 17
Transportation
Note:
a. Confirm that the quantity matches the order.
b. Label and stamp the outer box.
c. Send reports on shipments.
Step 18
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

The cover is constructed from high-quality AlSi10MnMg/DX17 aluminum alloy using an 800T die-casting machine. This material provides superior strength, corrosion resistance, and exceptional durability.
How is thermal management handled in this base station cover?
Aluminum has high thermal conductivity. The physical design of the cover allows it to effectively dissipate heat away from the electronics, minimizing overheating risk and ensuring the base station operates at peak efficiency.
What testing is performed to ensure the air tightness of the product?
We perform specialized air tightness testing with a pressure value of 20kPa to 30kPa. The pressure is stabilized for 10 seconds, and we ensure the leakage rate is strictly controlled within 0.3kPa.
What surface treatment processes are applied?
The manufacturing process includes dedicated cleaning, chemical conversion membrane treatment, and powder spraying to ensure a uniform color, consistent thickness, and maximum surface protection without any exposed substrate.
How do you guarantee quality control throughout production?
Quality control is integrated at every stage, including multiple IPQC inspections, 100% material inspection, FQC exams, and final OQC shipment checks. We utilize high-precision instruments such as calipers, projectors, pin gauges, and three-dimensional modeling.
