China is a casting power, but it is not a casting power. Although China's equipment foundry industry occupies a considerable share of the global foundry, it does not have strong independent innovation ability, let alone high-tech casting technology precision casting parts. Especially in the field of large castings, the quality and localization of large castings have become more and more serious constraints on the development of China's equipment manufacturing industry. Large key castings and forgings in numerous domestic major equipment localization projects are all dependent on foreign imports, and the technical performance and quality requirements of domestic castings are difficult to meet, which has become the bottleneck of the development of China's major equipment manufacturing industry.

China's domestic situation is different from that abroad. Compared with the industrial developed countries in Europe and America, the high-tech r&d and testing institutions are almost all concentrated in the major group companies, which makes it possible to apply a technology r&d in production in the first time after completion. In turn, the financial support of the group becomes the "backer" of the research and development institutions, thus forming a virtuous circle. And the competition between the groups makes the top management of the group to improve the technical support to the top priority. How to develop better technology to reduce costs and increase profits for enterprises has become the "small calculation" of executives.

And the technology of research and development is very difficult to enterprise production in the first time integration. Its closed information channels, cumbersome approval procedures, and the management philosophy of the enterprise's top management with no vision make the r&d technology into the enterprise production place for an unusually long time. When technology enters the enterprise, after a considerable period of smooth integration into production, it is almost obsolete. Such a vicious circle is undoubtedly a stumbling block for the development of China's equipment foundry industry and even all industries
