The simulation results consist of geometrical and manufacturing data. On the basis of the simulation results, part designers can optimize part geome- try, while mold designers can optimize the running and the cooling system of the mold. The authors developed a pro- gram which helps the programmers of the injection molding machine to transfer simulation data directly to the machine. Zhou et al. [1] developed a virtual injection molding system based on numerical simulation. Ma et al. [19] developed standard component library for plastic injection mold design using an object-oriented approach. This is an object- oriented, library model for defining mechanical components parametrically. They developed an object-oriented mold component library model for incorporating different geo- metric topologies and non-geometric information.
