  • Bead Die

    Primary tool in which the tube is bent around. We have an extension list of tooling online.

  • Beaded End

    A metal forming process that forms a bead on the end of a tube.
    Tube beads can be used to help hold a hose on the end of a tube or to strengthen the end of the tube. There are two forming processes: internal roll forming and ram forming, A.E.D's are processed using internal roll forming.

  • Beading

    Placing a raised narrow section around the diameter of the tube to allow a flexible tube to be clamped in place. Beading dimensions follow generally applied dimensional specifications.

  • Bend Angles

    The degrees or amount of bend applied to a part or bend section of tube. Standard bend angles for exhaust tubes are 30°, 45°, 60° and 90°. On aluminum water pipes 45°, 90° and 180° are most common. Many other parts can be made using custom angles. Standard tolerance is +/- .5°.
