With the rapid expansion of 5G technology, base stations play a vital role in ensuring seamless connectivity and high-speed data transmission.
 One of the main features of this product is its excellent durability. The cover is constructed from high-quality aluminum for superior strength and corrosion resistance, ensuring long-lasting performance in even the harshest environments. 
 In addition to durability, the aluminum cover offers excellent thermal management. The material's high thermal conductivity allows for efficient heat dissipation, preventing overheating and ensuring optimal performance of the base station. 
 In addition, the design of the lid is not only practical but also beautiful. Its sleek and modern appearance blends seamlessly with its surroundings, making it ideal for urban areas and public spaces.

Process

1, Aluminum die casting

Equipment: 400T aluminum die casting machine, Material: ADC12

Process characteristics
a. Furnace temperature: 670°±20°, Material handle: 20±2MM;
b. Secondary materials cannot be used;
c. Test the material composition to confirm that it is OK and can be produced;
d. First piece confirmation is required after die-casting.

Precautions:

a. The filling quality of the surface needs to be confirmed. No cold insulation, no bulging, or lack of material for the pillars. 
b. Pay attention to the surface to avoid sticking molds, drawing molds, or poor ejector pin convexity. 
c. The ejector pins are concave by 0-0.2mm for non-machine-added surfaces and 0-0.2mm for machine-added surfaces. The thimble needs to be convex 0-0.2mm.

2, Remove spout (Saw spout and knock out slag bag)

Equipment:  Sawing machine
Tools:  wooden stick

Precautions:

a, no crush injury or shortage of materials
b, Control the size and appearance.

3,  IPQC inspection (check dimensions according to drawings)

Test tool: Caliper / Projection / Three-dimensional

Precautions:

Use measuring tools correctly and check dimensions according to drawings.

4, Shaping (Product frontal shaping)

Equipmen: Cutting edge ruler / Shaping tooling/ Hydraulic presses

Precautions:

Inaccuracy within 0.25mm of the front of the product.

5, CNC

a: CNC- CNC machining (Process the end face of the inner cavity, the end face of the surrounding heat dissipation tooth surface, and the through holes of the tooth holes.)
b: Deburring (The sharp corners of the product are chamfered, deburred, non-machined ejector pins are sharpened, and polished to smooth the appearance.)
  c:100% inspection
Use of equipment and tools:
CNC machine/ Flat-bottomed cutter/ Drill bit
Tap processing fixture/ File / Wind grinder / 120# sandpaper

Precautions:

a, Do not over cut, no sand holes、no sharp corners、miss processing; without scratch, no burr; and the R corners should be connected smoothly.
b. Ensure the finish of the processed surface is Ra 0.8,  control the size and shape tolerances.
c.. Inspection by go gauge and no-go gauge .
d. Check the flatness of the product according to the drawing
e. Handle the product gently to prevent deformation

6, Polishing, (manual removal)
Remove product clamping line caps, surface particles, slag bags, and gate residues

Precautions: - No processing be missed、no sharp corners 、no harp edges and the mold closing line should be connected smoothly.

7, Outsourcing

Powder spraying(spraying in separate areas)
Test tools:
Appearance visual inspection + film thickness meter + colorimeter + salt spray tester + hundred grid test tool + alcohol resistance test + pencil test

Precautions:
a,The coloring and anti-bake fractal areas are obvious, no different colors, dirt, exposed bottoms, dust accumulation, scratches, etc.;
b, The color is consistent with the sample;

8, IPQC inspection/IQC incoming inspection

Precautions: 

a. Confirm the surface quality after powder spraying; 
b. The holes need to be randomly inspected by needle gauge,inspection by go gauge and no-go gauge.

9, 100% inspection
a, 100% inspect the appearance of the powder-coated.
b, Conduct random inspections for the powder-coated performance test.
Precautions:

a. The coloring and anti-bake fractal areas are obvious, no different colors, dirt, exposed bottoms, powder accumulation, scratches, etc.; 
b. The color is consistent with the sample

10, Dispensing glue (Dispensing glue on the defined rib area, dispensing width and height 1.0±0.1 symmetrically centered.)

Tools: Dispensing machine, dispensing fixture

Precautions:

1. Glue strips is uniform, no breakage, accumulation, drawing, glue overflow, deviation, bubbles, falling off, etc.
2. Ensure that the glue does not regenerate well or does not stick, and the glue strength is not ideal, etc.

11, 100% inspection(100% inspection of appearance + packaging)

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 gauge and no-go gauge;
c, The product is placed in the knife card, covered with flat cardboard on the upper layer, and then packaged.

12, FQC inspection

Test Tools: Caliper, projection, needle gauge, tooth gauge, appearance and outer packaging inspection

Precautions:

Whether the measuring tool is within the calibration period.

13, Shipping

Precautions:

a. make sure the quantity is the same as order.
b. Label and stamp on the outer box
c. Provide a shipping report.

14, OQC shipping inspection

Test Tools: Caliper, projection, needle gauge, tooth gauge, appearance and outer packaging inspection.

Precautions:

Whether the measuring tool is within the calibration period. Whether it is consistent with SIP requirements and customer requirements.
