Five cost saving methods of four column hydraulic press  
1. Reduce quality 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 stamping parts mostly need multiple sets of dies. The number of hydroformed engine carrier parts is reduced from 6 to 1, and the number of radiator support parts is reduced from 17 to 10.  
3. It can reduce the welding amount of subsequent machining and assembly.  
4. Improve strength and stiffness, especially fatigue strength, such as hydroformed radiator support.  
5. Reduce production costs.
