This machine is used to close, expand or reduce the ends of light alloy tubes. The end-forming operation is obtained by specially designed rotating tools, which heat the tube due to their rotation before deforming the extremeties. The exclusive “end-forming and closing” system is based on keeping the tube still and therefore allows to safety deform, with no limitation whatsoever, even already bent tubes, tubes with welded sleeves and of any length. The very short set-up time permits conveniency of machine use even if for very few pieces.
Copper tube closing capacity: Ø8÷Ø 89 mm*
Thickness: 2 mm
Tube minimum length (with no special equipment): 100 mm.
Tube maximum length: unlimited
Locking tube capacity: Ø89 with mod. BSR 80
Reducing & expanding capacity: considering that the shaping tools anneal the tube before the shaping operation, this value could change according to the hardness and the thickness of the copper tube inserted. Ask us for some examples.
* limitations are possible for expansion forming
