Numerical study on the effect of the die compression angle on extrusion forming of plastic pipe
The effect of compression angle of die on the extrusion forming of plastic pipe was numerically studied by using the finite element method.Based on the geometric models of plastic pipes with four different compression angles,the extrudate swell results of plastic pipe under the different compression angles are numerically simulated.Numerical results show the extrudate swell phenomenon for the little compression angles are larger than that of the large compression angles.To eliminate the extrudate swell effect and keep the wear-resistant strength of the plastic pipe,the gas-assisted extrusion method was used in this paper.The numerical results fully show that the shear stress of melt was greatly eliminated and the high pressure was still maintained by using the gas-assisted method.
