【Abstract】 The precise extrusion and the related machinery were reviewed. A new design for parallel pressure stabilization systems for single screw extruders was presented. A mathematical model was established based on the polymer conveying theory and simulation calculation was carried out with MathCAD. PE HD was selected to perform the experiments and the data was compared with the simulation. The results show that the system is efficient to achieve stable output and pressure for extrusion.更多还原
