Abstract
Method and apparatus for producing wire from an ingot, a method characterized in that it comprises the steps of applying force in the ingot to start the extrusion of the ingot simultaneously through a few primary means of opening the matrix and a second means of opening the matrix; after the extrusion of the ingot has begun simultaneously through the first means of opening the die and the second means of opening the die, and while maintaining the force on the ingot, gradually closing the second means of opening the die. Matrix; continue to apply force to the ingot to continue extruding it through the first means of opening the die to produce wire. (Machine-translation by Google Translate, not legally binding)
