Abstract
A novel approach is proposed to adjust flow nonuniformities caused by production variations from an extrusion die. A mathematical model that is based on the lubrication approximation was developed, and the effe ct of four types of production variations was examined separately. To each production variation, a specially designed choker bar was constru cted and inserted into the extrusion die to correct flow nonuniformiti es. (C) 1994 John Wiley & Sons, Inc.
