  • Method of hydroforming multi-lateral members from round tubes
    Patent number: 6032501
    Abstract: A method is provided for forming an elongated multi-lateral member from a round tube. A die is provided having a first die member and a second die member movable relative to the first die member between open and closed positions. The first and second die members define a first pair of opposed surfaces which each lie in a plane angled slightly with respect to an axis of movement of the second die member. The first and second die members further define a second pair of opposed surfaces which lie in a plane generally perpendicular to the first pair of opposed surfaces and which combine with the first pair of opposed surfaces to define a die cavity.
