Abstract :
A new method for manufacturing of arbitray cross section spinnerets. Application of UV-LIGA technique to fabricate the spinneret capillarys have been preliminarily discussed. Spinneret plate were deposited by electrotyping method firstly, then bond it with the outer frame using laser welding, the entire forming of spinneret is realized. The results show that the method not only can fabricate spinnerets with smooth surface and arbitray cross sections, but also have many advantages including high uniformity, high productivity and low cost.
