China Suppliers Factory Aluminum Casting Radiator Backplate Heatsinks for 5G Applications
Features
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 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
Aluminum Die Casting
- 800T aluminum die casting machine; ADC12 material
- The furnace temperature is 670°±20°, and the material handle is 20±2 mm.
- It is impossible to utilize secondary materials.
- Material composition must be tested to ensure it is suitable for production.
- After die casting, the first piece must be confirmed.
- Verify the quality of surface filling. There is no bulging, no cold isolation, and no shortage of materials in the column.
- Avoid mold stringing, sticking or insufficient ejector protrusion.
- For non-machined surfaces, the ejector pin should be concave 0-0.2mm, while for machined surfaces, the ejector pin should be convex 0-0.2mm.
Take Out Nozzle & Slag Bag
- Stick or saw
- Pay attention to the surface and don't damage it or use insufficient material.
- Manage size and appearance.
IPQC Inspection
- Three-dimensional, appearance visual evaluation, projection, calculator
Check dimensions against drawings and use accurate measuring equipment.
Dimension Check
Check dimensions against drawings and use accurate measuring equipment.
CNC (Deburring + Full Material Inspection + CNC Processing)
- 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)
- Burr Removal: To achieve a smooth appearance, the product's sharp corners are chamfered, deburred, and non-machined ejector pins are sharpened and polished. (Equipment: 120# sandpaper, wind mill, file)
- Inspection: Appearance visual assessment and 100% material inspection.
- Avoid excessive cutting or improper processing.
- Be careful not to burr or scratch the surface.
- Verify that the finish of the machined surface is Ra0.8 and that the size and shape meet the limits.
- The R corners should be connected smoothly, no burrs or sharp corners should be removed, and no processing should be missed.
- The product surface must be free of burrs, blisters, lack of material and other undesirable features.
- Use go gauge and stop gauge to detect.
- Verify product flatness against design.
- Handle items carefully to avoid deformation.
IPQC Inspection
- Visual inspection of appearance
Polish (Manual Removal)
Product clamp caps, slag bags, gate residues, surface particles, etc. need to be removed. The clamping line should be smoothly connected to other parts without removing sharp edges or corners.
IPQC Inspection
- Visual inspection of appearance
Powder Spraying
Appearance visual inspection combined with colorimeter, film thickness meter, salt spray tester, hundred grid tester, alcohol resistance test, pencil test.
- 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.
IPQC / IQC Incoming Inspection
Visual inspection of appearance; inspection of specific quality.
- Verifying surface condition after powder coating.
- Randomly inspect/test holes using a pin gauge or a hole gauge.
Full Inspection & Packaging
Dividers, containers, bubble wrap and desiccant.
- Appearance needs to be checked based on samples. 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.
FQC Exam
Calipers, projectors, pin gauges, tooth gauges, visual and packaging inspection.
Verify that the measurement device is still within its calibration window.
Transportation
- Confirm that the quantity matches the order.
- Label and stamp the outer box.
- Send reports on shipments.
OQC Shipping Inspection
Calipers, projectors, pin gauges, tooth gauges, outer packaging inspection, etc.
Confirm if the measuring device is still within its calibration window. Verify whether it meets both customer and SIP requirements.
