From the Paper:

"Another way to help achieve isothermal extrusion is to treat the billet in a way that will give it a tapered temperature profile. This can be achieved by a couple different methods. First, the billet can be heated unevenly before extrusion. This can be done with either induction heating machines or with gas fired machines as long as they have separate sections for heating along the length of the billet. Another method is to heat the billet evenly and to cool the tail end of the billet before it is loaded into the extrusion press. These methods are useful in industry, however because of the high heat conductivity of aluminum if there is any delay in the extrusion process the billet temperature tends to become uniform. Because of this tendency of aluminum it is beneficial to have a cooling system incorporated into the press. By passing water or another cooling medium such as nitrogen around the container in the correct locations the temperature gradient in the billet can be maintained."
