Flow analysis of the die and the torsional multiplying element in mould based on ANSYS

Polymer melt flowing in the multiplying element and matched die was simulated for the flowing uniformity and pressure distribuiton based on ANSYS. The results of simulation revealed that the height difference between outlet and inlet sections of the channels in multiplying element, the length of transition region and forming region of molding die all affected pressure distribution and velocity uniformity at the outlet.
