Abstract: To formulate good die casting process and to improve die casting efficiency and utilization rate of resources,a die casting process pattern recognition based on D-S evidence theory was proposed.By analyzing the die casting process and its mechanism,the key factors affected on die-casting was confirmed.Based on large number of historical accumulated data of die casting process,a new die casting process model for new product requirement was achieved by analyzing various factors with D-S evidence theory.The effectiveness of the proposed method was verified and explained by a typical case of die casting technology.The example showed that this method could use the process data effectively and realize the process design of new products.

Key words: die casting process, D-S evidence theory, pattern recognition
