  • Low friction end feeding in tube hydroforming
    Patent number: 8910500
    Abstract: An end plunger for end feeding during a hydroforming process (such as tube hydroforming) has at least one releasable seal. The effect of the releasable seal is that it avoids pressurizing the blank in a nip area, thereby reducing friction and wear, and allowing increased end feeding with a given end feeding force. The releasable seal may be actuable, for sealing or releasing. The plunger may be modular or monolithic. A kit and method may incorporate the end plunger.
