Process
01
Aluminum Die Casting
Equipment & Material:
800T aluminum die casting machine; ADC12 material
Process Characteristics:
- 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.
Precautions
- Verify the quality of surface filling. 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.
02
Take Out the Nozzle (Saw Nozzle) & Pull Out the Slag Bag
Tools:
Stick or saw
Precautions
- Pay attention to the surface and don't damage it or use insufficient material.
- Manage size and appearance.
03
IPQC Inspection
Testing Instruments:
Three-dimensional, appearance visual evaluation, projection, calculator
Precautions
Check dimensions against drawings and use accurate measuring equipment.
04
Dimension & Precision Validation
Note
Within 0.25 mm from the front of the product.
05
CNC (Deburring + Full Material Inspection + CNC Processing)
Sub-Processes:
-
a. 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. -
b. Burr: 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. - c. Appearance visual assessment and 100% material inspection.
Note
- 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.
06
IPQC Inspection
Details:
Visual inspection of appearance
07
Polish (Manual Removal)
Details:
Product clamp caps, slag bags, gate residues, surface particles, etc. need to be removed.
Note
The clamping line should be smoothly connected to other parts without removing sharp edges or corners.
08
IPQC Inspection
Details:
Visual inspection of appearance
09
Regional & Organizational Powder Spraying
Test Equipment:
Appearance visual inspection combined with colorimeter, film thickness meter, salt spray tester, hundred grid tester, alcohol resistance test, pencil test.
Note
- 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.
10
IPQC Inspection / IQC Incoming Inspection
Details:
Visual inspection of appearance; inspection of specific quality.
Preventative Measures
- Verifying surface condition after powder coating.
- Randomly inspect/test holes using a pin gauge or a hole gauge.
11
Full Inspection of Appearance + Packaging
Consumables:
Dividers, containers, bubble wrap and desiccant
Precautions
- 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.
12
FQC Exam
Testing Instruments:
Calipers, projectors, pin gauges, tooth gauges, visual and packaging inspection
Note
Verify that the measurement device is still within its calibration window.
13
Transportation
Prepare for a rainy day
- Confirm that the quantity matches the order.
- Label and stamp the outer box.
- Send reports on shipments.
14
OQC Shipping Inspection
Testing Instruments:
Calipers, projectors, pin gauges, tooth gauges, outer packaging inspection, etc.
Note
Verify if the measuring device is still within its calibration window and whether it meets both customer and SIP requirements.
Frequently Asked Questions
What materials are used in the manufacturing of the base station cover?
The cover is manufactured using high-quality ADC12 aluminum. This material is chosen for its superior strength, corrosion resistance, and excellent thermal conductivity, ensuring long-lasting performance even in demanding conditions.
How does the aluminum cover manage heat control?
Aluminum has high thermal conductivity. The cover design effectively dissipates heat from the internal components, minimizing overheating and ensuring that the base station operates at maximum efficiency.
What quality control checks are performed during production?
We implement multiple stages of quality control including In-Process Quality Control (IPQC) inspection, Incoming Quality Control (IQC) inspection, Final Quality Control (FQC) evaluation, and Outgoing Quality Control (OQC) shipping checks. Testing instruments such as three-dimensional projectors, calipers, and film thickness meters are utilized.
What surface treatment processes are applied to the product?
The product undergoes deburring, manual polishing to remove clamp caps, slag bags, and gate residues, followed by regional and organizational powder spraying to guarantee uniform color and long-lasting protection.
How are the products protected during transportation?
Products undergo a full appearance inspection and are packed using specific protective materials including dividers, containers, bubble wrap, and desiccant. They are layered with flat cardboard to prevent scratches, dents, or structural damage.
Are secondary materials used in the die casting process?
No, the utilization of secondary materials is strictly prohibited. Raw material composition must be thoroughly tested before production to ensure structural and chemical compliance.
