  • a liquid pressure medium is used to build up an internal pressure the workpiece present as a hollow body.
  • material properties and material thicknesses can be printed are between about 800 and about 10,000 bar.
  • additional mechanical forces can be used, which cause additional flow of workpiece material into the forming zone. This additional forces can act in the axial or radial direction and lie in of the order of about 800 to about 3000 bar.
  • Hydraulic oils are used as pressure media (use because of their Compressibility limited to pressures below about 1500 bar) or aqueous Media based on water-miscible products containing mineral oil or synthetic solutions, as they are also in the field of Cooling lubricants are known.
  • the object of the present invention is a new lubricant mixture to make available, in particular as external lubrication at the IHU, however, it can also be used for other non-cutting forming processes.

  • the waxes are caused by the oil liquefied. They improve the lubricating effect of the oil and lead to a very low coefficient of friction. Because of the liquefaction by the oil Wax easily along with the oil using standard aqueous cleaners from the to remove surfaces covered with it. Inadvertently, but often inevitable entry into the print medium there is no risk of Blockage of fine nozzles.
