Advantages of hydroforming technology of four-column hydraulic press

1 Reduce mass and save material. For typical parts such as automobile engine brackets and radiator brackets, hydroforming parts are 20% to 40% lighter than stamping parts; for hollow stepped shaft parts, the weight can be reduced by 40% to 50%.

2. Reduce the number of parts and molds and reduce mold costs. Hydroforming parts usually only need one set of dies, while stamping parts mostly require multiple sets of dies. The number of hydroformed engine bracket parts has been reduced from 6 to 1, and the number of radiator bracket parts has been reduced from 17 to 10.

3. It can reduce the amount of welding in subsequent machining and assembly. Taking the radiator bracket as an example, the heat dissipation area is increased by 43%, the number of solder joints is reduced from 174 to 20, the number of processes is reduced from 13 to 6, and the productivity is increased by 66%.

4. Improve the strength and stiffness, especially the fatigue strength. For example, the stiffness of the hydroformed radiator bracket can be increased by 39% in the vertical direction and 50% in the horizontal direction.

5. Reduce production costs. According to the statistical analysis of the applied hydroformed parts, the production cost of hydroformed parts is 15% to 20% lower on average than that of stamping parts, and the mold cost is reduced by 20% to 30%.
