Abstract

An extrusion apparatus is described in which a removeable die 12 is located in a die chamber 7 within a body 6 of the apparatus. A passageway 26 leads from an inlet 25 for extrusion material to the die chamber 7. A general squared-section sealing ring 30 is positioned in the passageway adjacent to the die 12. The sealing member 30 has the corner next to the face of the die 12 and passageway wall 26 chamfered. so that extrusion material pressing against the sealing ring forces that ring into sealing engagement with the die face and passageway wall in order to present undesirable flow of extrusion material about the die into the die chamber.
