Abstract

A die unit for extrusion apparatus, especially Conform apparatus, comprises a die 10 and die holder 11. The die is supported in the holder but is surrounded over at least a substantial part of its length by a sleeve 12 extending from the working face between the die and the die holder and made of a metal soft compared with the die and the die holder. Suitable metals are mild steel and the metal being extruded. Round wire can be formed. [EP0131426A2]
