Abstract
The present invention reveals a manufacturing method of a fluororesin bundle having a plurality of fluororesin tube hold by a fixing element as a bundle. The bundle is pre-sealed when the ends of the fluororesin tubes are heated to a status being deformable and mount on the fixing element while being place in a vacuum environment and receive a thermal energy. Immersing the pre-sealed bundle into a heating pool to extend the mounted surface between the fluororesin tubes and the fixing element. Thus, a high quality fluororesin bundle can be done by using the above processes.
