As an important component of large-scale extruder system for polymer material, Die-plate can be regarded as the final determinant for pelletization uniformity. Polymer melt was shaped in shaping channels and extruded from die-holes from Die-plate and then be diced. The design of shaping channels directly influences the uniformity for polymer-melt extrusion pressure and extrusion velocity of different die holes. In this paper, a three-dimensional flow model for polymer flow in Die-plate channel was presented, and then finite element simulation was used to analyze the distribution of extrusion velocity in each die-hole. Based on simulation result, a BP neural network model was applied to analyze the relationship between geometry factors of Die-plate, such as length of shaping channels, die hole extrusion velocity distribution, and extrusion uniformity. This optimization method can be used in the design of Die-plate to improve effect and quality of actual polymer production and processing.

As an important component of large-scale extruder system for polymer material, Die-plate can be regarded as the final determinant for pelletization quality. Flow fluctuation of extruder and die-hole blocking can be summarized as two uncertainties for pelletization quality problem. A Liquid-Solid-Liquid coupling FEM method is presented to simulate factors of temperature distribution, flow distribution and flow rate control. Based on the calculations and mechanism analysis, pelletization quality degree and assessment framework are designed and calculated to analyze the impact of operation uncertainties to final product. With the simulation and evaluation framework, control methods for pelletization quality are discussed for Die-plate design and operation condition settings.
