All kinds of casting method for precision castings is different, the initial investment and productivity are notconsistent, the ultimate economic benefits are also different. Therefore, to do more, fast, good,province,consideration shall be given to all aspects of. Deal with selected casting method carries on the preliminary cost estimation, to determine high economic benefit and can ensure the casting requirements of the casting method.
Although China's foundry industry is in a difficult period,however, from the long-term point of view, China'sprecision casting industry development there are still some hope,market demand has been slowly began to pick up, and withChina foundry industry development has a position of relative strength, believe that the castingindustry in Chinawill surely achieve gratifying achievements.
Experts said, in order to fundamentally improve the castingtechnology level must do the following four points:first, the development of simulation technology, improve the accuracy of forecasting, strengthening the process control,improve the rate of finished products. The regularity of the problem to master is not very good, thus affecting theproduction yield. Second, the combination. Independent innovation of enterprises in addition toinnovationawareness and enhance R & D capability, but also need topay attention to and strengthen theprecision casting enterprise as the main body of the "production, learning and research," the combination of.Third, pay attention tomaterials research and development. Material is the foundation of industrial, there are still a lot of work to do at present. In the field of aerospace alloys, especially high temperature alloy and somenew material research,smelting technology remains to be improved, and there is still a large gap betweenforeign. Fourth, pay attention toequipment and technology promotion. The process orequipment problems,many of the key equipment, such as some directional solidification equipment mainly rely on imports, so theprecision casting equipment R & D is stillheavy.
