... . The material flow can be equalized to overcome the transverse forces by using a relieving extrusion, also referred to as a follower. This relieving extrusion is usually a round bar, as shown in Fig. 7.33 . An additional insert die can be machined into the die body of large extrusion tools, for example...

... ) are common. They are named differential because the functional (pressurized) area of the piston is not equal when the rod is extending and retracting. As a result, the rod can generate more force when extending but moves slower than when it is retracting (see Eq 12.1 and 12.2 ). In some applications...
