With this technology it is possible to shape different types of materials and different thicknesses without having to change the die, because it is the water that adapts itself to the thickness of the sheet. Moreover, the sheet metal is deformed uniformly, and when the hydraulic pressure stops, the spring-back is reduced to a minimum as well as uniform over the entire surface of the piece, in this way you get maximum stability and the absence of geometric distortions.
The method used by Inoxveneta is water punch hydroforming that required various steps:
The water punch hydroforming is best for:
The use of sheet metal hydroforming is restricted by the need to employ presses with much greater force than is normally required for conventional hydraulic pressing. For this reason Inoxveneta has acquired a press machine with a force of 6,000 tonnes, built to an innovative concept which keeps costs down.
