Abstract: A forming process of plastic parts is simulated. The position and time of plastics particles which exceed at least one defined critical limit are detected. The final positions of particles in the surface layer of the plastics part are computed. The positions of the particles in the surface layer are defined as positions with deviations in the surface appearance.

Abstract: A method for simulating deviations in surface appearance of plastics parts caused by a forming process of plastics parts is shown, comprising the steps of a) Simulating the forming process of the plastics part, b) Detecting position and time of plastics particles which exceed at least one defined critical limit, c) Computing the final position of those particles in the surface layer of the plastics part, d) Defining the position of those particles in the surface layer as a position with deviations in the surface appearance.
