China Suppliers Factory Aluminum 5G Base Station Enclosure with Die Casting Heatsink for Outdoor Use
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 1
Aluminum die casting
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:
- 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.
Step 2
Take out the nozzle (saw nozzle) and close the slag bag
Note:
- Pay attention to the surface and don't damage it or lack of material.
- Manage size and appearance.
Step 3
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.
Note:
- The product shall not be non-sanded areas and fonts missing, playing collapsed edges, poking.
- The product shall not have residual phi, shall not miss the phi, particles.
- If bad or other emergencies occur in a timely manner, isolate and immediately report to the superior to deal with.
- Pay attention to the transportation and processing process, hold and put the product lightly, do not bump the lack of, hit the deformation.
- Hang the hangtag and product identification on the top of the cardboard, QC signature OK before transferring to the next process.
Step 4
IPQC inspection
Precautions:
- Use measuring tools correctly and check dimensions according to drawings.
Step 5
Product back shaping
Caution:
- Within 0.3 mm from the front of the product
Step 6
IPQC inspection
Visual inspection of appearance
Step 7
CNC
Machining of internal cavity end faces, Backside holes, Side of one end, Hole through-hole
Precautions:
- Do not overcut, missed processing;
- Surface attention must not be bruised, burrs; and
- Ensure that the surface finish Ra1.6 size, shape and location tolerances.
Step 8
Air tightness testing
Test pressure value in 20kpa ~ 30kpa, stabilized pressure 10 seconds, test time 10 seconds, leakage control within 0.3kpa
Precautions:
- Do a good job on the product appearance surface protection, sealing groove parts without implementation of touch scratch;
- Discover the phenomenon of air leakage in time to pick out the marking.
Step 9
100% material inspection
Visual inspection of appearance
Precautions:
- The surface of the product should not be overcut, sand holes, lack of material. Burrs, and other undesirable phenomena
- go-no go fixed gauges inspection
- Test the flatness of the product according to the drawing.
- 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.
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
Standard chemical conversion and coating application.
Note:
- No different colors, dirty, not touching and scratching;
- Color according to the sample, uniform and consistent;
- Powder thickness is uniform, no accumulation of tumors, no exposed bottom.
Step 13
IPQC inspection + Special Characteristics Inspection
Visual inspection of appearance
Note:
- Surface quality confirmation after chemical conversion membrane/power spraying;
- Hole need to needle gauge sampling, go -no go fixed gauges inspection
Step 14
Riveting and pressing D4.7 dowels
Precautions:
- 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;
- Check the height dimension after pressure riveting;
- 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
Precautions:
- 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!
- The tooth pattern must comply with the go – no go fixed gauge inspection;
- The product is placed in the knife card, and then packaged.
Step 16
FQC exam
Note:
- Verify that the measurement device is still within its calibration window.
Step 17
Transportation
Logistics and shipment preparation.
Note:
- Confirm that the quantity matches the order.
- Label and stamp the outer box.
- Send reports on shipments.
Step 18
OQC shipment 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 material is used for the base station cover, and what are its key properties?
The cover is made of high-quality aluminum (specifically AlSi10MnMg/DX17). This material offers superior strength, corrosion resistance, and excellent thermal conductivity for effective heat dissipation.
How do you ensure the air tightness of the manufactured enclosures?
We perform air tightness testing using specialized airtight tooling and test equipment. The process requires a test pressure of 20kpa to 30kpa, stabilized for 10 seconds, with a total test time of 10 seconds. The leakage must be controlled within 0.3kpa.
What quality control checks are performed during the manufacturing process?
We implement multiple inspection stages, including IPQC (In-Process Quality Control), 100% material inspection, FQC (Final Quality Control), and OQC (Outgoing Quality Control). These checks utilize calipers, projectors, pin/tooth gauges, three-dimensional modeling, and visual inspections.
What surface treatments are applied to the aluminum covers?
The covers undergo a thorough cleaning process, followed by the application of a chemical conversion membrane and powder spraying. This ensures uniform color, correct thickness without accumulation, and optimal environmental protection.
How are the parts packaged to prevent damage during transit?
Products are fully inspected and then packaged using dividers (such as knife cards), protective containers, bubble wrap, and desiccant to prevent scratching, denting, moisture damage, or deformation during transportation.
