The productivity of an extrusion press is decided by how fast each die can run without defects. That speed is not a free choice. It is boxed in by the pressure the press can deliver, by the temperature at which the surface starts to tear, and by the minim ....

A new extrusion die rarely runs perfectly on its first billet. The first length that leaves the die, the nose piece, shows how the metal flows through each part of the opening. Reading it correctly tells the die corrector where the flow is fast, where it ....

Hollow aluminum profiles such as tubes, window frames and heat-sink housings are extruded through porthole dies. The billet is split into several streams, the streams pass around a mandrel that forms the inside of the profile, and they weld together again ....

In an extrusion die, every part of the profile opening must release metal at the same speed. If one wall runs faster than its neighbour, the profile bends, twists, waves or tears. The bearing, the short land that gives the profile its final shape, is the ....

Most defects on aluminum extrusions come from one of three places: the die, the billet, or the press settings. A fourth group arises after the die, during quenching, pulling, stretching and ageing. Knowing which area to look at first saves trials and scra ....
