How sheet metal hydroforming works

The method used by Inoxveneta is WATER PUNCH HYDROFORMING:

• A sheet of metal is placed on the working surface
• The press closes to block the sheet on the table and hold it in place
• The flui flows in through a nozzle against the sheet metal, forcing it against the die surface, until it takes the final shape of the piece
• Once the cycle is complete, the die opens and the finished piece extracted

• Panels
• Sloping/conical surfaces
• Geometries with complex and/or several parts

• Better quality surfaces
• Uniform material stretching
• Possibility to achieve special shapes (cavities, undercuts, etc.)
• Manufacture of lightweight pieces
• Increased mechanical precision for components (external tolerance)
• Reduction of spring-back

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 with a force of 6,000 tonnes, built to an innovative concept which keeps costs down.
