1. Special shaped parts with complex forming space structure

2. It can form profile bending parts with large yield strength ratio

3. Integrated forming of different process methods

4. High bending precision and small springback

In automobile production, profile stretch bending is mainly used to process hollow aluminum bending parts of body structure and bumper. Under the condition of maintaining the same impact strength as steel parts, the weight of the vehicle body can be reduced and the use cost can be reduced. The stretch bending process can realize the high-precision bending of aluminum profiles.
