In this paper, the results of experimental investigation are using PVC molten is used as the coating material in a extrusion unit at different extruder temperatures, extruder speeds and shear rate value.The quality of extrusion is emphasis the extruded plastics material viscosity as first indicator parameters in polymer extrusion. Also parameter which primarily determines of the viscosity is shear rate.The other parameters are extruder temperature, and single screw rotation speed. This nümerical model to evaluate the viscosities of thermoplastic polymers in the extrusion process for quality control proposed in this article. PVC was used in this study to test the effectiveness of the model. Comparing the available results, it was found that the viscosities obtained with the nümerical model are in agreement with those obtained by using an in line rheometer. The result shows that the this method can be applied to control the polymer extrusion process. The topic of this paper is the design and experimental testing of a PID control system for the desired of the barrel temperature, extruder pressure and shear rate in a polymer single single screw extruder. Simulations of PID Control algorithms for coating process have been made and the results of these simulations was observed. There are a comparison of PID Controller and nümerical results and there are comments about this comparison in these studies. The simulations of the algorithms are done in MATLAB 2010 a packaged program environment.
