Die Development for Fiberization of High Performance Adhesives, 2000 Hot Melt Symposium Proceedings
Rick J. Klaus--When product designers are considering the use of high performance adhesives the challenge has always been to define the correct adhesive application method that will work. Numerous papers and studies have been written and conducted over the last forty-five years concerning die design and fluid flow characteristics. The purpose of this paper is to review the basic types of existing die geometries as well as newly developed geometry for use with various high performance adhesives and resins. Fiberization of these materials requires good control of cross web uniformity and residence time, as well as shear history. This paper will not get into the mathematical proofs of which die design is better for a given fluid, but instead concentrate on the types of dies available and the flow aspects associated with them.
