Tube welding lines with cage forming FCF® technology

Anyone who would like to economically produce shaped tubes (square/rectangular) very fast and very flexible in the dimension change will find out that SEUTHE tube welding lines with a patented forming method are technologically far ahead.

Already in 1993 VAI SEUTHE has developed the cage forming FCF technology (Flexible Cold Forming), a method to directly form tubes without a previous round tube - in different dimensions, small batches and intermediate sizes.

The direct forming avoids a thickening of material in the corner radii and provides an optimal utilization of the strip material. Consequently between 2 to 5 % material can be saved by using the cage forming FCF technology. As a next step of development "retrofitting", barcode readers as well as the use of state-of-the-art communication protocols are planned.

Economical production of smallest quantities

The principle of the FCF technology is simple, but convincing: The metal strip is fed from the coil in the forming section and then pulled continuously by tools. Universal, centrally adjustable roll sets for direct forming of square and rectangular sections in the range of 20 x 20 mm to 400 x 400 mm (with different line sizes) allow extremely fast dimension changes. This results in an economic production of especially very small quantities. Benefits of cage forming FCF technology at a glance:

  • Reproducible settings
  • High availability
  • Economic production
  • Minimal tooling costs
  • Flexible production of all intermediate sizes
  • Simple operation
  • Fastest changeover times
