Using Technology Development Co., Ltd. Beijing North Fang Hengli casting process design and development of process simulation CAStsoft CAD / CAE technology castings module, process heat section calculated risk system to calculate the pouring, pouring the process, the solidification process of casting rough calculation of the process to defects in the design and analysis of casting process, according to the results of process improvements, and finally design a reasonable casting process. Computer simulation of the casting process can reduce or cancel the process of new product test, which can effectively avoid possible casting defects, to ensure the reliability of technology, new products and shorten the trial period. Casting simulation technology used to guide new product development and process optimization, no doubt can achieve a multiplier effect.
