| For a global estimation of the extrusion process, the knowledge of the melting process is of a great importance. To calculate melting length and the solids bed profile, a modified TADMOR model is used. This estimates the location de-pendent molten film thickness on the cylinder wall amongst the inclusion of radial leakage flows. The solution of the melting process in the channel direction results from the energy balance in the molten film above the solid bed and the mass balance between the melt pool and the melt film, see figure. | For a global estimation of the extrusion process, the knowledge of the melting process is of a great importance.
