Evolutionary economic tube production for wall thickness up to 2 mm

Greater flexibility
Requirements for flexibility in terms of length and diameter, the reducing of changeover times, and program-controlled changeover without change parts are the strength of the Ecostar.

Freedom when it comes to tube geometry
In addition to the advantages for short tube production - without the shape-specific reworking of the tubes - the Ecostar offers tremendous freedom in terms of tube geometry. The Ecostar's core is the automatic diameter adjustment in roll forming and welding. The roll formed sheet is joined by radially movable clamping bars on the outside and is continuously welded under a stationary welding optic.

Areas of application
With its dimensions, the Ecostar is ideally suited for the production of catalytics converter housings, round/oval small containers, pressure tanks and similar products.

Extensions
The Ecostar can be extended with these modules:

  • Seam planishing, to eliminate any height offsets in the weld seam
  • Laser marking for tube traceability
  • Annealing at approx. 500°C in order to optimize a subsequent expansion or calibration
  • Calibration or spinning for catalytic converters
  • Loading of different stacks of blanks for the automatic processing of orders with different tubes
  • Coil loading of the Ecostar by means of a directly connected cut-to-length line
