Fetures

This cutting-edge product combines advanced technology with superior functionality to provide the ultimate solution for your base station needs.
1, Excellent heat dissipation capabilities. As the demand for high-speed data transmission increases in 5G networks, thermal management becomes critical to ensure optimal performance. Our housings are designed to effectively dissipate heat, preventing overheating and ensuring smooth operation of the base station.
2,Excellent corrosion resistance. This is especially important for outdoor installations, where exposure to harsh weather conditions can cause damage to the equipment. Our enclosures are built to withstand the elements, protecting your base station from corrosion and extending its lifespan.
 3, lightweight and easy to handle and install. This is a significant advantage, especially when it comes to deploying base stations in remote or challenging locations. The lightweight design not only simplifies the installation process but also reduces transportation costs.

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 back shaping)

Product back shaping
Equipment : knife-edge ruler, shaping fixture

Precautions:

Within 0.25mm of the front plane 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.
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

7, Outsourcing

Powder spraying + Oil Spraying(Two-color 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 (Check the appearance of powder spraying)

a, 100% inspect the appearance of the powder-coated.
b, Conduct random inspections for the powder-coated performance test)

Precautions:

1. The painted and anti-bake fractal area is obvious, and there is no abnormal color, dirt, exposed bottom, dust accumulation, scratches, etc.;
