Using Explosive Hydroforming To Create Spherical Tanks (a mouthful but just hit play to see what we mean)

 

Explosive hydroforming, also known as HERF (High Energy Rate Forming) or exploform, is a striking alternative to the more traditional process of metal hydroforming. Unlike this older method, which shapes metal using pressurized hydraulic fluid pumped into a forming chamber, HERF techniques utilize an explosive charge to create the necessary pressure. Although the charge is relatively small, it is capable of generating enough force to mold the associated metal into the die.
