Title (EN) EXTRUSION MACHINERY
(FR) MACHINE A EXTRUDER
Abstract:
(EN) A two wheel (10, 12) conform type aluminum extrusion machine and a die assembly (18) and subassembly (38) for extruding tubing or cladding a core material (116). The die subassembly (38) permits lateral adjustment of a die ring (94) relative to a mandrel (91) to ensure uniform wall thickness in the extruded tubing. A method of utilizing the die subassembly (38) comprises assembly thereof and prefilling the subassembly with molten aluminum.
(FR) Machine à extruder de l'aluminium du type à deux roues (10, 12) comportant un ensemble (18) et un sous-ensemble (38) pour extruder des tubes ou plaquer une matière formant une âme (116). Le sous-ensemble matrice (38) permet l'adaptation latérale d'un anneau de matrice (94) par rapport à un mandrin (91) afin d'assurer une épaisseur de paroi uniforme des tubes extrudés. On décrit aussi un procédé d'utilisation du sous-ensemble matrice (38) comprenant le montage dudit sous-ensemble et la préinjection d'aluminium fondu dans ce sous-ensemble.
