ABSTRACT:
An evaluation method analyzes flow on molding of a molten material. This is achieved in a system of making a flow analysis on an in-mold molten material through division of a molded part model into minute elements and numerical analysis thereof including the calculi of finite elements, boundary elements, finite differences, FAN and the like. One or more temperature conditions of the molten material are provided with a plurality of loading times or mold temperatures respectively for performing an analysis and from the obtained operational results of the pressure distribution of the molten material a function of the maximum molten material pressure of each element is provided. This function is graphically indicated on a display apparatus to evaluate the appropriate ranges of the molten material pressure and the loading time at a predetermined molten material temperature.
