Abstract

On décrit un tube (10) présentant une paroi (12) mince qui s'étend entre des première (14) et seconde (16) extrémités et possède une épaisseur (t) inférieure à environ 0,03 pouce. Ce tube (10) comporte également une nervure (22) qui s'étend longitudinalement et est formée sur la périphérie (18) intérieure du tube. Grâce à cette nervure (22), on peut mouler par injection ce tube (10) à paroi mince à partir d'un matériau thermoplastique, en utilisant des plages de température standards ainsi que des temps de cycle relativement courts.
