What is the production of mobile phone LCD aluminum frame?
The production of mobile phone LCD aluminum frames is a complex and precise process involving multiple steps and technologies. The following is a detailed production process to help you understand the entire process from raw materials to the final product:
1. Material selection
Aluminum alloy materials: 6063 or 6061 aluminum alloys are usually selected, and these alloys are widely used for their good mechanical properties, workability and corrosion resistance.
2. Aluminum alloy melting and casting
Melting: The selected aluminum alloy material is heated in a furnace to its melting point (about 660°C), so that it is completely melted.
Casting: The molten aluminum alloy is formed into a preliminary aluminum frame shape by die casting or extrusion process. Die casting is suitable for the production of complex geometric shapes, while extrusion is more suitable for the production of long products.
3. Precision machining
CNC machining: The use of computer numerical control (CNC) machine tools to precisely cut and drill preliminary aluminum alloy parts. This step ensures the dimensional accuracy and shape accuracy of the aluminum frame.
Grinding and polishing: remove surface burrs and uneven parts to make the surface of the aluminum frame more smooth.
4. Surface treatment
Anodizing: An oxide film is formed on the surface of the aluminum frame to improve corrosion resistance and wear resistance, and to allow coloring.
Sandblasting: Fine abrasive particles are sprayed onto the surface of the aluminum frame through high pressure air to produce a matte effect.
Plating or other coating: Depending on the design requirements, plating or other types of coating treatment may also be applied to enhance aesthetics or functionality.
5. Quality inspection
Size check: Use high-precision measuring tools to check whether the size of the aluminum frame meets the design specifications.
Appearance inspection: Manual or automated equipment to detect the surface for defects, scratches or other defects.
Physical performance test: including hardness test, tensile strength test, etc., to ensure that the aluminum frame meets the mechanical performance requirements.
6. Preparation for assembly
Preassembly: As required, add necessary accessories or components to 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.
