Mobile phone LCD aluminum frame processing
The processing process of mobile phone LCD aluminum frame is a key step to ensure its accuracy, durability and beauty. The following is a detailed processing process to help you understand the specific process from
Aluminum Alloy Sheet to the final product:
1. Material preparation
Material selection: Select suitable aluminum alloy materials, such as 6063 or 6061, which are widely used for their good mechanical properties and easy processing characteristics.
2. Preliminary molding
Cutting: According to the design drawings, the aluminum alloy sheet is cut to the desired size and shape using a saw or laser cutting machine.
Stamping/die casting: For designs requiring complex shapes, preliminary molding can be done by stamping or die casting.
3. Precision Machining (CNC)
Programming: According to the design drawings, write numerical control programs on the computer.
Processing:
Milling: A CNC milling machine is used to remove excess material and form a precise shape and internal structure.
Drilling holes: Drill holes in the specified position for subsequent installation of screws or other fasteners.
Turning: If you need parts with cylindrical or other rotationally symmetrical shapes, you can use a lathe for machining.
4. Surface treatment
Deburring: The removal of burrs produced during processing by hand or mechanical means.
Sanding: Use sandpaper or a sander to smooth the surface.
Anodizing: An oxide film is generated on the surface of the aluminum frame to improve corrosion resistance and allow dyeing.
Sandblasting: Fine abrasive particles are sprayed onto the surface of the aluminum frame through high pressure air to produce a matte effect.
Electroplating or other coatings: Other functional or decorative coatings can also be electroplated or sprayed on demand.
5. Quality control
Dimensional check: Use high-precision measuring tools (such as a coordinate measuring instrument) to check whether the key dimensions of the aluminum frame meet the design requirements.
Appearance inspection: Manual or automated equipment to detect surface defects, scratches and other defects.
Physical performance testing: including hardness testing, tensile strength testing, etc., to ensure that the aluminum frame meets the mechanical performance standards.
6. Preparation for assembly
Preassembly: According to the design requirements, add the necessary accessories or components on the aluminum frame, such as screw holes, interfaces, etc., for subsequent assembly with the LCD screen and other components.
Cleaning treatment: Thoroughly clean the aluminum frame to ensure no dust and oil, and prepare for the subsequent process.
7. Packaging and delivery
Packaging: ESD packaging materials are used to prevent damage to the aluminum frame during transportation.
Shipping: After rigorous quality inspection, the product is properly packaged and shipped to downstream manufacturers for final assembly of the phone.
Matters needing attention
The importance of precision machining: Because mobile phone LCD aluminum frames require very high precision, the CNC machining step is particularly critical. Any small error can cause assembly problems or affect the overall quality of the product.
Choice of surface treatment: Different surface treatment methods not only affect the appearance of the aluminum frame, but also affect its durability and functional characteristics, such as electrical conductivity, heat dissipation and so on.
