Abstract: Aiming at the problem of poor melt fluidity of nylon PA6 in extrusion process,the influence of runner structure of extrusion die with six cavities for nylon PA6 bar on melt flow unibity was studied based on melt flow theory and computational fluid dynamics simulation b. The results showed that the primary and secondary factors affecting the melt flow unibity were the radius, length of straight section and spacing of the runner. The optimum beters of runner structure were obtained, the numerical analysis results showed that the pressure drop along the extrusion direction from the inlet of the main runner to the outlet of the shunt runner was similar, the volume flow rate of melt flowing through each shunt runner was equal.

words: nylon PA6; multi-cavity inline; extrusion die; runner structure; flow
