The repair of automotive steel rims is mainly to solve two problems, which are indispensable and complement each other:

　　1. Automobile steel ring shape repair. Generally, the damage of automobile steel ring is caused by the external force, such as: wear, fracture, notch, depression, distortion, deformation, etc. When the automobile steel ring is repaired, it does not damage the aluminum alloy molecules. In the case of structural and mechanical properties, the application of aluminum alloy professional technology and tools to correct and repair various types of automobile steel ring damage and other problems; improved the past situation of automobile steel ring deformation, twisting, fracture and other irreparable repairs.

　　Second, the refurbishment of the surface of the automobile steel ring. If the shape of the automobile steel ring can only be repaired, and the surface of the automobile steel ring cannot be renovated, the repair of the automobile steel ring also loses the significance of repair.

　　The surface of automotive steel rings can be divided into four categories, namely: painted surface, polished surface, numerical control (CNC) surface and electroplated surface. The surface of the refurbished automotive steel ring can meet the OEM quality requirements in terms of appearance and hardness In the past, due to the special treatment process of the surface of the automobile steel ring, such as: CNC treatment, electroplated surface and other scratches, scratches, etc., which have not been repaired have become history.
