What are the cost-saving methods for four-column hydraulic presses

What are the cost-saving methods for four-column hydraulic presses?

Reduce weight and save materials. For typical parts such as car engine brackets and radiator brackets, hydroformed parts are 20% to 40%

 lighter than stamped parts. For hollow stepped shaft parts, the weight can be reduced by 40% to 50%.

Reduce the number of parts and molds and lower the mold cost. Hydraulic forming parts generally only require one set of molds, 

while stamping parts mostly need multiple sets of molds. The number of engine bracket parts formed by hydraulic forming has 

been reduced from 6 to 1, and the number of radiator bracket parts has been reduced from 17 to 10.

It can reduce the amount of welding in subsequent mechanical processing and assembly. Take the radiator bracket as an example. 

The heat dissipation area has increased by 43%, and the number of weld points has been reduced from 174 to 20. The number of processes 

was reduced from 13 to 6, and the productivity increased by 66%.

Enhance strength and rigidity, especially fatigue strength. For instance, the rigidity of a radiator bracket formed by hydraulic forming can 

be increased by 39% in the vertical direction and by 50% in the horizontal direction.

Reduce production costs. Based on the statistical analysis of the hydroformed parts that have been used, the production cost of hydroformed  

parts has decreased by an average of 15% to 20% compared with stamping parts, and the mold cost has decreased by 20% to 30%.
