1. Reduce weight and save materials.
2. Reduce the number of parts and molds and reduce the cost of molds. Hydroforming parts usually only need one set of dies, while most stamping parts need more than one set of dies. The number of engine bracket parts reduced from 6 to 1, and the number of radiator bracket parts decreased from 17 to 10.
3. It can reduce the welding amount of subsequent machining and assembly..
4. Improve the strength and stiffness, especially the fatigue strength, such as the hydroforming radiator bracket,
5. Reduce production cost.
