Extrusion presses are specifically designed to produce aluminium cans, tubes and similar products, starting from an aluminium slug through the extrusion method (material due to the impact force generated by the machine goes up on the punch and forms the classic cylindrical shape, with variable diameter, length, wall and bottom thickness depending on the force and slug thickness used). Can or tube are therefore made in one stroke of press, at a speed that can reach 330 strokes per minute, according to the machine size (force) and the can/tube to be produced. These machines are the head of large integrated production lines, completely automated, they run 24 hours a day, 7 days a week and they need to be extremely accurate to assure the maximum reliability either for the intrinsic difficulty of the extrusion method and for their intensive way of use. Balconi has been on the market of extrusion presses since many years with its machines installed all over the world, which have been subject to continuous improvement and updating in recent years. The Balconi new generation of extrusion presses: The press kinematic with connecting rod designed with a modified double knuckle-joint system allows to obtain a 30% reduction of the impact speed on the punch, compared to the traditional systems and it assures a better extrusion of the can/tube. The crankshaft is completely balanced to reduce vibrations. Flywheel is mounted on an independent housing fixed to the press frame for a better stability during running and it is automatically lubricated.
