Experts say, to fundamentally improve the level of casting technology it has to do the following four points:A, development of simulation technology, improve the accuracy of prediction, to strengthen the process control and improve the yield.Command of regularity of the problem is not is not very good, thus affecting yield in mass production. Second, the unity.Enterprise independent innovation in addition to the growth of awareness of innovation and ability of the research and development, also need to attach importance to and strengthen to precision casting enterprise as the main body of the combination of "production, study and research".Three, pay attention to material research and development.Material is the foundation of the industry, there are a lot of work to do.In the field of aerospace, alloy materials, especially the high temperature alloy research, some new materials such as smelting technology remains to be improved, and foreign gap bigger also.4, pay attention to equipment technical improvement.Process is mainly on the equipment problems, a lot of key equipment, such as some directional solidification equipment mainly rely on imports, so the precision casting equipment research and development is still the focus.
