In recent years, with the increasing pressure of market competition, the fastening casting industry in order to maintain stable development, has been combined with market and product mix, in the development of ideas to constantly adjust and enhance development effectiveness in the adjustment, innovative economic growth, achieved good results. Currently, North America, Western Europe and Asia is the world's three major markets tightening castings, castings also our major export markets tightening, the annual demand were more than $ 10 billion. With the accelerated development of air transport equipment, aerospace fastening casting class will get better development on the basis of growth in the 2007-2012. Growth in industrial fastening casting OEM market will exceed MRO market, but sales of fasteners in the MRO market will grow on the basis of 2007-2012, mainly due to growth in fixed investment, as well as with the expansion of production tightening casting equipment will also be applied to increase. In addition, the U.S. production of metal products also appear to rise, "return" to the trend of many industries, but also one of the factors supporting the growth in demand of castings fastened. By 2017, demand for standard fastening castings will be expected to exceed demand for aerospace products. Among them, the standard male thread fastening casting will occupy the largest market share, and get the most rapid growth. In the period of transformation and upgrading, innovation is the key, especially in the foundry industry, should develop and master the sophisticated core technology to enhance competitive advantage. In recent years, these enterprises to accelerate the pace of technological innovation, the current form of a number of distinctive enterprises, including high-strength special fastening 15% casting, heat treatment products accounted for 60% and other products accounted for 40%. With the continuous development of China's foundry industry, fastening casting has become one of the larger import and export volume of China's products, which not only realized with international standards, but also to promote the Chinese enterprises to the world fastening castings, castings fastened to enhance international business had an important impact on competitiveness.
