Patent ID: 7959837

Claim:
A method of forming a compacted disk, comprising the steps of: a) inserting a mixture of material into a cavity running through a die casing, b) positioning a first plunger in alignment with said cavity so that said first plunger may engage said mixture of material when said first plunger is moved downwardly into said cavity, c) positioning a second plunger in alignment with said cavity so that said second plunger may engage said mixture of material when said second plunger is moved upwardly into said cavity, d) positioning a polymeric seal ring circumferentially around at least a portion of the outer surface of said first plunger so that said seal ring lies flush against at least a portion of the outer surface of said first plunger, wherein the first plunger has a tip surface facing said mixture of material, wherein said seal ring is positioned in proximity to said tip surface of said first plunger, e) moving said first plunger downwardly into said cavity so that at least a portion of said seal ring enters said cavity and said mixture of material is compacted against a portion of said second plunger thereby forming a compacted disk, wherein as the first plunger moves downwardly into said cavity to compact said mixture of material at least a portion of said seal ring enters said cavity f) ejecting said compacted disk from said cavity by moving said first and second plungers upwardly within said cavity, wherein as said first plunger moves upwardly to eject said compacted disk said disk presses against the seal ring, wherein the pressing of said compacted disk against and the seal ring prevents a web of flashed material from forming and from attaching to said compacted disk as said disk is being ejected from said cavity.
