2, attaches great importance to the precision casting materials 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, with foreign gap is larger.3, 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 the combination of "production, study and research".4, precision casting simulation technology development, improve the forecasting accuracy, 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.Precision casting is among the more common investment casting, also known as the lost wax casting, choose suitable investment pattern materials for investment;Touch on casting refractory coating and sand and refractory process, sclerosis type shell and dry;Then the internal casting melt away, get the cavity;Roasting shell in order to obtain enough strength, and burn off the remnants of casting material, pouring need metal materials;After shelling solidification cooling, deoxidization, can achieve the high precision finished products.
