A method to automatically set injection grading speed and pressure of the injection machine

This paper presents an injection model and a method for setting grading injection pressure and speed automatically by a kind of engineering experiment. The injection model is established based on the physical process of mold filling, and then is solved by the computer calculation for gaining grading points. This method can obtain the injection classification parameters without accurate mathematical model, is especially suitable for setting the injection parameters automatically when installing mold on injection molding machine.
