Abstract

La présente invention concerne une buse ultra-fine capable d'assurer la sortie régulière d'un écoulement liquide, le diamètre interne de l'extrémité de la buse n'étant que de 30 m ou moins et l'épaisseur des parois de la buse étant réduite, la buse ultra-fine étant utilisable dans divers appareils médicaux ou industriels, ainsi qu'un procédé de production de cette buse ultra-fine. La solution proposée consiste à réaliser les étapes suivantes : un fil central (43) est spécialement électrofondu (première électrofusion), une partie du fil central (43) est mise à nu, un tuyau électrofondu de forme effilé (41) auquel le fil central (43) reste attaché est formé, une seconde électrofusion est réalisée pour former un second tuyau électrofondu (44), puis le fil central (43) et le premier tuyau électrofondu (41) sont étirés afin de produire une buse ultra-fine intégrée utilisant des tuyaux électrofondus dont les diamètres internes et externes sont différents. L'extrémité de la buse peut être effilée ou bien ses parties internes et externes peuvent être plaquées avec un métal tel que l'or, l'argent ou le palladium.
