1. The reason for the re-deformation of aluminum plate after plastic shaping may be caused by the elastic properties of metal materials. Aluminum plate is a kind of metal material with certain elasticity, which will be elastically deformed when subjected to external force. If the forming process of aluminum plate is not accurate enough or disturbed by external force, it may lead to elastic deformation and eventually lead to deformation again after forming.

2. Processing methods and techniques: Different processing methods and techniques will also affect the deformation after plastic surgery.

3. Aluminum alloy sheet is an industrial building material, which is used in various industries according to different materials and can be divided into two categories according to surface treatment methods: unpainted products and painted products.
