Extrusion die assembly

Image Number 8 for United States Patent #8113810.

An extrusion die assembly includes a hollow extrusion head which has a head inner surface, a central passage inlet opening, a forming section having a die opening, and a receiving space that extends from the central passage inlet opening to the forming section. A flow-dividing core is disposed within the receiving space, and has a central passage connected to the central passage inlet opening and extending to the forming section, and a grooved outer surface that is disposed upstream of the forming section and that has at least one groove which cooperates with the head inner surface to define at least one accumulating passage. An annular passage is formed in the forming section and around the flow-dividing core and the central passage, is connected to the accumulating passage, and merges with the central passage in the die opening.
