METHOD FOR PRODUCING DIALYSIS TANK CHAMBER FRAME

摘要

There is provided a method for producing a chamber frame for a dialyzer, which is readily produced, has a stable quality, is inexpensive and is excellent in sealing property and heat resistance. A cut frame 1 is set on an unshown table of an impulse welder 30, distributors 13 are fitted into communicating passage 9 and communicating passages 11, and a net 15 is positioned so as to cover a central opening 3. Welded portions A and B, and the welded portions C and D are subjected to impulse welding. Mounting of the net 15 as a spacer and mounting of the distributors 13 are carried out simultaneously by a single pressing operation. After that, the welded portions of the net are deburred, and correction work is performed on defects.
