Four-Column Hydraulic Press

1. Reduce quality and save materials. For typical parts such as automobile engine brackets and radiator brackets, hydroformed parts are 20%-40% lighter than stamped parts, and for hollow stepped shaft parts, the weight can be reduced by 40%-50%.
2. Reduce the number of parts and molds. Reduce tooling costs. Hydroformed parts usually only need one set of molds, while stamping parts mostly require multiple sets of molds. The number of hydroformed engine bracket parts was reduced from 6 to 1, and the number of radiator bracket parts was reduced from 17 to 10.
3. It can reduce the amount of welding for subsequent machining and assembly. Taking the radiator bracket as an example, the heat dissipation area is increased by 43%, and the number of solder joints is reduced from 174 to 20. The process is reduced from 13 to 6, and the productivity is increased by 66%.
4. Improve strength and stiffness, especially fatigue strength. For example, the rigidity 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 applied hydroformed parts, the production cost of hydroformed parts is 15%-20% lower than that of stamping parts on average, and the mold cost is reduced by 20%-30%.
