Polymer injection molding: advanced simulations or tablet computations

Simulation of injection molding of polymeric materials is a common way of solving issues in plastic part and injection mold design. CAE software is getting more available and user-friendly, which sometimes leads to unreasonable use cases of these programs. The original, relatively simple tool has been introduced to validate runner systems in injection molds. It allows a fast identification of the most important design parameters of runner system. This tool does not require any support of FEM simulations, but results obtained from it have been successfully compared with injection molding simulations.
