Forging of railroad rails with KIERMAR

A unique cylinder concept forges a rail with 3 forging operations in less than 60 seconds


The Kiermar 5500 tons AFP is fast, much faster than conventional presses.

Generally, rib-web shaped asymmetric rails for an express train are produced in a specified fixed shape, but the shape transforms to symmetric at the rail turnouts. Because of the difference in height and shape between the two shapes, it is impossible to forge in a single-stage operation. Therefore, a process design for multi stage forging is needed.

  • High speed handling and forming with only one heating operation.
  • Very low power consumption due to smaller movements in the press.
  • Fully automated production with minimum costs for operators.
  • Main frame structures without welding will give an almost endless lifetime.


  • Low investment.
  • High output capacity.
  • Great energy savings.
