Cellphone Middle Frame Battery Back Cover Aluminum Shell

The manufacturing process of aluminum alloy mobile phone backplane is a complex and delicate process, which involves multiple steps and technologies. Here are some of the main manufacturing processes:   1. Selection of raw materials Aluminum-magnesium alloy, aluminum-manganese alloy, aluminum-silicon alloy, etc., are commonly used aluminum alloy types, and they have different characteristics and application scenarios. 2. Design and modeling Using CAD software (such as UG) for 3D modeling, design the specific shape and structure of the back of the phone. Aluminum Parts For 3C 3. CNC machining Aluminum extrusion: The aluminum alloy through the extrusion press to form a sheet or profile. Rough milling of the inner cavity: Rough machining of the initially formed back plate to remove excess material and prepare for subsequent finishing. Precision milling of surfaces and sides: high-precision cutting using CNC machines to achieve the size and shape required by the design. Milling anten…
