Hot Extruding

larger image
During hot extrusion a round steel billet is pre-heated and, after leaving the furnace, is pushed through a forming die into a profile bar using a ram with an extrusion force of 2,200 t. Hot extruding offers substantial advantages in comparison with hot rolling, forging or machining.

Hot extrusion can be used to make complex steel profile shapes even using metals which are difficult to form. In addition, small lot sizes can be produced economically.

We possesses highly sophisticated CAD and CAM systems which are used to support our customers during the design and engineering phases.

    Hot extruded steel profiles offer the benefit of :
  • different material thicknesses within one profile cross-section
  • the possibility to use in highly sensitive areas, where the special profiles must with stand specific demands of temperature, pressure, aggressive media or hygienic requirements
  • seamless structure of solid and hollow sections
