Extrusion presses

Extrusion presses

Extrusion molding is a pressure forming process used in the manufacture of rods, pipes, wires as well as profiles, above all of aluminum, but can also be copper, copper alloys, steel and other metals and alloys. With this process a billet is pressed through a die, which determines the external shape of the press train. The internal shape can be influenced by differently formed mandrels. With its unique power-density, the fact that no maintenance is required and high availability, hydraulics is ideally suited to the drive of the main axis of an extrusion press.


Requirements of components/ systems:

  • Systems with a nominal force of up to 140 MN require high flow rates and pressures
  • Energy efficiency
  • Control axes for even quality of the extrusion press profiles
  • Easy handling of the components
  • High energy efficiency
  • Low maintenance requirements
