Abstract: An extrusion press method for production of sintered blanks comprising at least one internal, spirally extending channel, the plastic material forming the blank being pressed out of the mouth of a nozzle of an extrusion press in the form of a substantially circular cylindrical pipe. The plastic material which exits from the mouthpiece of the nozzle in a substantially twist-free manner flows along the axis of at least one spirally twisted pin which is maintained in a stable position on a gudgeon of the nozzle. The pin does not rotate, the plastic material in the mouth is displaced in a twisted flow corresponding to the spiral shape of the pin and the rotational movement of the plastic material is supported by a rotationally driven section of the mouth, which is engaged on the outer periphery of the material such that the pin is essentially not subjected to bending deformation.
