Abstract (en)
[origin: WO2012158051A1] The subject of invention is the method of extruding elements, especially made of metal, and a system for extruding elements, especially made of metal, employed for production of elements by means of extrusion. The material 4 is deflected from the infeed wheel I tangentially or at an angle within 90° and is caused to flow locally within the area of the die 5, by the mandrel's 7 rotary action. This method is executed in a system where in the gap's 3 output area there is a wedge 6 to deflect the direction of exit of the material fed by the rotating infeed wheel 1, and in the space between the friction block 2 and the deflection wedge 6 there is a mandrel 7 caused to cyclically move bidirectionally at frequency of (0.1-10) Hz, whose face contacts the material in the area of transfer into the die 5.
