STAMPING OF HIGH ELASTIC LIMIT SHEET METAL TO LIGHTEN VEHICLES

The lightening of vehicles can be achieved by using high elastic limit steels. This allows the sheet thickness to be halved compared to standard steel.

However, the stamping of this type of steel requires high-speed forming methods that are still not well known, such as electro-hydraulic forming.

The aim is to digitally simulate the manufacturing process in order to have a better knowledge and control of it.

The digital modelling of the electro-hydraulic forming process integrates the formation of the plasma channel in water. Its very rapid extension generates a high velocity shock wave, which hits the sheet metal to shape it.

Project profit
Reduce the number of physical tests to obtain the final product and thus​ reduce the time for developing and producing moulds.​ Reduce prototyping costs for parts obtained by electro-hydraulic forming for high elastic limit steel parts.
The world just needs you to turn differently
