Impact extrusion presses
Presses are an integral part of production lines for cylindrical hollow containers.
Presses are an integral part of production lines for cylindrical hollow containers. They are the first machines in an extensive and complex manufacturing process. They set the pace and define the geometric quality of the manufactured cylinders. Higher grade aluminum alloys as well as a thin wall technology in aluminum cans place even greater emphasis on presses.
It all starts with an aluminum slug with thickness of several millimeters. During the forming process, the material flows in reverse direction against the motion of the press between the punch and a die. The result is a thin walled aluminum cylinder, the basis for various metal packaging containers. Integration between impact-extrusion press and production line has always been a critical factor for the quality of the end product.
