Abstract

In this paper, a three-dimensional model of the pressing of polyetheretherketone (PEEK) particles is constructed using the finite element analysis software MSC. Marc finite element analysis software and based on discrete unit theory to study the displacement of the bulk particles and the variation of the stress-strain of the particles during the pressing process. The effects of press force, lubrication conditions and other process parameters on the relative density of the bulk particles were analyzed. The results show that increasing the pressing force within a certain range can increase the density of the bulk pellets, and that the lubrication conditions need to be improved to further increase the relative density. Numerical simulations are used to obtain the maximum pressing forces for different materials and to provide guidance for improving and optimizing the process parameters in practical production.
