Technical requirements and industrial development of nonferrous metal precision castings
- Oct 19, 2018 -

The precision requirements and cost of non-ferrous metal precision castings, the precision of the castings obtained by various casting methods are different, the initial investment and production efficiency are also inconsistent, and the final economic benefits are also different to some extent, therefore, To be more, faster, better, and more economical, we should take into account all aspects. The initial cost estimation should be carried out on the casting method chosen, so that the casting method with high economic efficiency and the requirements for casting can be determined.


Non-ferrous metal precision castings From a long-term perspective, China's precision casting industry still has certain hopes for development, and its market demand has slowly begun to pick up, coupled with the strong strength of China's foundry industry development, I believe that China's The foundry industry will certainly achieve gratifying results.


To fundamentally improve the technical level of non-ferrous metal precision castings, the following four points must be achieved.


First, develop simulation technology to improve the accuracy of prediction, strengthen process control, and improve yield. The problem of regularity is not well mastered, thus affecting the yield in mass production.


Second, the combination of production, study and research. In addition to the enhancement of innovation consciousness and the improvement of research and development capabilities, the independent innovation of enterprises also needs to attach importance to and strengthen the combination of “production, learning and research” with precision casting enterprises as the main body.


Third, attach importance to material research and development. Materials are the foundation of industry, and there is still a lot of work to be done. In the aerospace field, research and smelting techniques for some new materials such as alloy materials, especially high-temperature alloys, have yet to be improved, and the gap with foreign countries is still large.


Fourth, pay attention to the improvement of equipment technology. The process is mainly the problem of equipment. Many key equipments, such as some directional solidification equipment, mainly rely on imports, so the research and development of precision casting equipment is still the focus.
