Abstract: The plastic die materials optimization expert system complies with the principle of meeting the required properties of dies, taping the latent power of die materials and having reasonable economy and feasible technology. According to the proposed technique requirements by users, it would recommend the selected die materials with requisite technique data through optimization inference of materials selection, the technique documents management of user, the knowledge management of system and the management of system. The system is developed in windows environment by means of Visual C6.0 and inference process is operated on the basis of the rules or examples. It also provides the friendly and transparent interfaces with the Chinese demonstration, fast operating capacity and convenient application.
