Abstract

In an extrusion process according to the parent Specification, a closure member 4 is provided at the die outlet, a second closure member 7 is provided between the billet 8 and the ram 5 and the latter has a mandrel- 6 extending through the closure 7 and the hollow billet. The upper closure 7 is pressed from sheet metal and seals against the container wall and the mandrel by the pressure of the lubricant in the extrusion chamber.
