Zusammenfassung |
AB |
[EN] A method for producing a tubular semi-finished product for an implant scaffold which leads to an improvement of the dilatability of the scaffold. The semi-finished product consists of a magnesium alloy. The method includes extruding a tubular semi-finished product by a heated die or tempering an extruded tubular semi-finished product by a heating device. A tube drawing device applies a tensile stress and/or a torsional stress. The tube drawing device has a clamping device. The clamping device is fixed on a predefined portion of the tubular semi-finished product. Tensile force generated by the tube drawing device and/or the torsion moment generated by the tube drawing device is transferred to the semi-finished product. |
