Aluminum Material Selection and Cutting: We start by selecting high-purity aluminum alloy plates. These plates are cut using laser cutting or CNC sawing to obtain the necessary blanks according to the back plate's specifications.

Extrusion Molding: Using multi-station molds, the aluminum is cold stamped, a process that includes blanking, stretching, and punching. This shapes the flat aluminum into a three-dimensional structure that fits the phone's curvature, while also creating precision holes for cameras and other functions.

CNC Precision Machining: The edges and holes of the back plate are then milled using CNC technology, ensuring that dimensional tolerances are maintained within ±0.02mm for precise fit and function.

Surface Treatment:

• Anodizing: The aluminum surface is treated through electrochemical anodization to form a wear-resistant and corrosion-resistant oxide layer. This process also allows for multi-color options, including black and silver, to meet various aesthetic needs.

• Sandblasting: Sandblasting improves the surface texture, adding anti-slip properties and a sophisticated visual finish.

Inspection and Assembly: After completing the machining process, we inspect the back plate's dimensional accuracy using 2D image measuring instruments and coordinate measuring machines. The back plate is then assembled with the phone's midframe and screen components to complete the full integration of the device.
