Most billets used for extrusion are cylindrical but square billets may be used. An extrusion method is, for example, a hot working method including placing a cylindrical aluminum billet in the container 11 interposed between the extrusion die 12 and the stem 13 and moving the stem 13 to extrude the billet into a product from the extrusion die 12. ![]() 1, an extrusion press 10 used for extrusion generally is constructed by a container 11, an extrusion die 12 fixed to one end of the container 11, a stem 13 movably mounted on a pushing ram at the other end of the container 11, and a bolster 16 for fixing the container 11 and the extrusion die 12 through a backer 14 and a die ring 15. ![]() The present invention relates to a method of determining at least one dimension of an extrusion die, and an extrusion die produced based on the method.Īs is obvious from its schematic structure shown in FIG. The contents of that application are incorporated herein by reference in their entirety. 6, 1999, entitled “Method Of Producing Extrusion Die, Apparatus For Producing The Same, And Extrusion Die Produced By The Method”. ![]() The present application claims priority under 35 U.S.C.
