A thermoplastic, unibody transfer device

摘要

The present invention is directed to a thermoplastic, unibody transfer device. This transfer device includes a membrane (11), and a housing (18) surrounding the membrane (11). The housing (18) includes a thermoplastic end cap (22) and a thermoplastic shell (20). The end cap (22) and shell (20) are butt welded together. Additionally, there is a method of manufacturing with the aforementioned device. The method includes forming a bundle of a membrane (12), inserting the bundle (12) into a shell (20), butt welding an end cap (22) to the bundle (12) and the shell (20) so that the cap (22), bundle (12), and shell (20) are fused together.
