China OEM Aluminium 5G Telecom RRU Die Casting Housing - Reliable Suppliers & Factory Solutions
Feature
With the rapid development of 4G technology, base stations have become increasingly important in ensuring smooth connections and fast data transmission.
The product's exceptional durability is one of its main advantages. The cover is made of high-quality aluminum for superior strength and corrosion resistance, ensuring long-lasting functionality even in the most demanding conditions.
The metal lid 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 maximum 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
300T Aluminum Die Casting
Material: ADC12
Characteristics:
• Material handle: 20±2mm
• Furnace temperature: 670°±20°
• Secondary materials not allowed
• Composition verified through testing
• First piece confirmation required post-casting
Preventive Measures
• Verify surface filling quality (no bulges, cold insulation, or lack of material in pillars).
• Prevent poor ejector pin crown, mold pulling, or mold sticking.
• Ejector pins must be concave by 0-0.2 mm for non-machined/machined surfaces, and convex by 0-0.2 mm.
2
Nozzle & Slag Bag Removal
Take out the nozzle (saw nozzle) and pull out the slag bag.
Tools: Sawing machine
Equipment: Wooden stick
Precautions
• Protect the surface from damage and avoid insufficient material.
• Strictly manage size and appearance.
3
IPQC Inspection
Check dimensions according to drawings.
Inspection Tools: Caliper, projector, 3D, appearance visual inspection.
Precautions
Use measuring tools correctly and verify dimensions match drawings.
4
Shamping (Back of Product)
Equipment: Knife Ruler, Forming Tool, Hydraulic Press.
Precautions
Ensure the product front error is within 0.25mm.
5
CNC Processing
a. Processing: Internal cavity end face, peripheral heat dissipation tooth face end face, punching through hole processing.
b. Deburring: Chamfer and deburr sharp corners; polish non-machined ejector pins for smoothness.
c. Inspection: 100% inspection.
Tools: CNC machine tools, flat bottom milling cutters, drills, tap processing jigs, file, wind grinder, 120# sandpaper.
Precautions
• No overcutting, blisters, sharp corners, missing processing, scratches, or burrs. R corners must connect smoothly.
• Ensure processing surface finish is Ra 0.8; control size and shape tolerances.
• Conduct inspections according to go/no-go rules.
• Check product flatness against drawings and handle carefully to prevent deformation.
6
Polishing (Manual Removal)
Remove product clamping caps, surface particles, slag bags, and gate residues.
Precautions
No leakage processing, no sharp corners, no vertical edges, and smooth connection of the mold closing line.
7
Outsourcing
Process outsourcing stages.
Precautions
• Ensure the coloring and baking-resistant fractal area is obvious.
• No abnormal color, dirt, exposed bottom, dust accumulation, or scratches.
• Color must remain consistent with the sample.
8
IPQC / IQC Inspection
IPQC inspection and IQC incoming material inspection.
Precautions
• Confirm surface quality after powder spraying.
• Randomly inspect holes with pin gauges, check with pass and stop gauges.
9
100% Inspection
a. 100% check the appearance of the powder coating.
b. Conduct spot checks on powder coating performance tests.
Precautions
• The coloring and baking resistance fractal area must be obvious.
• No abnormal color, dirt, exposed bottom, powder accumulation, or scratches.
• Color must be consistent with the sample.
10
Glue Dispensing
Width and height asymmetry centered at 1.0 ± 0.1, glued to designated strip area.
Tools: Dispensing jigs and machines.
Precautions
• Ensure strips are even; no cracking, piling, pulling, spilling, deflecting, blistering, or falling off.
• Verify glue adhesion, regeneration, and optimal glue strength.
11
100% Inspection & Packaging
100% appearance + packaging inspection.
Precautions
• Inspect appearance based on samples. Surface must be free of dirt, scratches, dents, and defects. Glue must be applied evenly.
• Tooth shape must comply with general rules and stop rules.
• Place product into the knife card, cover upper layer with flat cardboard, then package.
12
FQC Inspection
Inspection Tools: Calipers, projectors, needle gauges, tooth gauges, appearance, and outer packaging inspection.
Precautions
Verify whether the measuring tool is within the calibration period.
13
Shipping
Final shipping preparation.
Precautions
• Make sure the quantity is the same as the order.
• Apply labels and seals on the outer box.
• Provide shipping reports.
14
OQC Shipping Inspection
Inspection Tools: Calipers, projectors, pin gauges, tooth gauges, appearance, and outer packaging inspection.
Precautions
Verify whether the measuring tool is within the calibration period and meets SIP and customer requirements.
Frequently Asked Questions
What material is used for the base station cover, and what are its advantages?
The cover is made of high-quality ADC12 aluminum material using a 300T die casting machine. This material offers exceptional strength, outstanding corrosion resistance, and high thermal conductivity, which helps dissipate heat and prevents overheating during operations.
What parameters are controlled during the aluminum die casting process?
Key parameters include maintaining the material handle at 20±2mm and the furnace temperature at 670°±20°. The process strictly prohibits the use of secondary materials, requires composition verification through testing, and mandates first piece confirmation after die casting.
How is quality control managed during CNC processing?
CNC processing ensures a surface finish of Ra 0.8, with rigorous checks to prevent overcutting, blisters, sharp corners, scratches, or burrs. Flatness is checked against drawings, and go/no-go rules are strictly applied.
What are the specifications and precautions for the glue dispensing step?
Glue dispensing requires a width and height asymmetry centered at 1.0 ± 0.1 mm, applied to the designated strip area. The glue strips must be even without cracking, piling, spilling, or bubbling, and the glue strength must be fully verified.
How are products inspected and packaged before shipping?
Products undergo 100% appearance checks and FQC/OQC inspections using calibrated calipers, projectors, needle gauges, and tooth gauges. They are packaged securely by being placed into knife cards with flat cardboard covering the upper layer.
