Abstract

L'invention concerne un procédé et un dispositif servant à produire des corps tubulaires. Selon l'invention, une préforme en matériau thermoplastique produite par une technique de moulage par injection est transformée en contenant dans un moule de soufflage par expansion biaxiale. La transformation se fait par un processus d'étirage et par acheminement d'un gaz de soufflage sous pression. Le contenant est retiré du moule de soufflage sous la forme d'un produit intermédiaire et une région de base du contenant est découpée. Au cours d'une dernière étape de production, le bord de coupe est comprimé et soudé. L'obturation du contenant tubulaire peut avoir lieu avant ou après le remplissage.
