ADC12 Aluminum Die Casting 5g Communication Base Station Aau Micro Site Shell

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,Pay attention to the surface without crushing or shortage of materials.
b,Control the appearance and size

3, IPQC inspection (check dimensions according to drawings)
Test tool: Caliper / Projection / Three-dimensional / visual inspection of appearance
Precautions:
Use measuring tools correctly and check dimensions according to drawings.


4, Shaping (Product back shaping)
Equipmen : Cutting edge ruler / Shaping tooling/ Hydraulic presses
Precautions:
Inaccuracy within 0.25mm of the front of the product.


5, CNC:
a: 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
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 + 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:

    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:
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 (Dispense adhesive to the specified bar area, dispensing width and height 1.0±0.1 symmetrically centered.)
Tools: Dispensing machine, dispensing fixture
Precautions:
a. Glue strips is uniform, no breakage, accumulation, drawing, glue overflow, deviation, bubbles, falling off, etc.
b. Ensure that the glue does not regenerate well or does not stick, and the glue strength is not ideal, etc.

11, Assembling (Assembly of accessories)
a,Corresponding assembly position of heat dissipation copper bar for glue assembly;
b,Lock the corresponding position of sheet metal parts M2.5*5 screws to press the heat dissipation copper block;
Parts:
SE4450 Glue
5x Heatsink Copper Bars
3x Sheet metal parts
6x M2.5*5 half-round screws


Precautions:
a,Copper bar dispensing slot is filled with glue according to the sample;
b,Ensure that the lock screw position is stable without loosening and slipping teeth.

12, Baking (drying)
Put the products in 2 columns and 7 rows, total 14pcs neatly on the baking line, baking temperature 150ºC, time 30 minutes.
Equipmen : dryer
Precautions:
Leave a certain gap between the product placement, pay special attention to not touching the tunnel door; hold lightly; do not touch the scratches;

13, 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.

14, 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.

15, 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.

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