A nozzle comprising: a nozzle body having a passageway configured to be in fluid communication with a source or resin and an exterior surface comprising a first shoulder extending generally outwardly from a first contact surface; a retention ring disposed about a first portion of said exterior surface of said nozzle body and extending generally outwardly from said nozzle body, said retention ring comprising a first material that is weld-compatible with said nozzle body; a weld between said retention ring and said first portion of said nozzle body; and a seal comprising a second material that is not weld-compatible with said nozzle body, said seal surrounding at least a portion of said contact surface of said nozzle body, wherein said seal substantially abuts against at least a portion of said first shoulder and said retention ring such that seal substantially cannot move relative to said nozzle body.

L'invention concerne un appareil perfectionné de buse (1) et un procédé de fabrication. Selon l'invention, des composants non-compatibles (tels qu'une extrémité de buse (3) et un joint d'étanchéité (8) dont les métaux ne sont pas compatibles lors du soudage) peuvent être fixés/attachés. Par exemple, l'appareil et le procédé peuvent comprendre la fixation d'un joint d'étanchéité (8) entre une première partie d'une extrémité de buse (3) et une bague de retenue (30). La bague de retenue (30) peut comprendre un matériau qui est compatible lors du soudage avec l'extrémité de buse (3) et peut être soudé à l'extrémité de buse (3) tandis que le joint d'étanchéité (8) peut ne pas être compatible avec l'extrémité de buse (3). En conséquence, les matériaux de l'extrémité de buse (3) et le joint d'étanchéité (8) peuvent être choisis pratiquement sans prendre en considération leur compatibilité.
