Abstract: The
mathematic model of the co-extrusion of polymer with metal insert is
established by using the penalty finite element method. The simulation
program is coded and a co-extrusion process of polymer of Carreau fluid
with metal insert is simulated. The distribution of the
three-dimensional velocity field of polymer in die cavity is obtained.
Through solving the energy equation by SUPG formulation, the temperature
field of polymer is obtained while the convective term dominates in
energy equation. The influence of various volume fluxes on the velocity
field of the polymer is studied. The result shows that the analysis of
the example gave the common rule of the co-extrusion process of polymer
with metal insert. The simulation results supplied theoretical
guidelines for the process and mould design of the co-extrusion of
polymer with metal insert.
