Flow of a polymer in the plasticizing process of an injection molding machine is analyzed. A polymer in the heat barrel of the machine is regarded as an imaginary non-Newtonian fluid irrespective of melting. Its mathematical model is solved by FEM based on the adjoint variational principle. In order to obtain initial states in the entire analyzed area, the steady-state problem is first solved. Next, using its results as initial values, the original nonsteady problem is analyzed. Moreover, the boundary conditions are also considered.
