Abstract: China's sales volume and sales volume of engineering machinery have both surpassed that of the United States, Japan and Germany, ranking the first in the world. The self-sufficiency rate of engineering machinery in China has increased from about 70% during the tenth five-year plan period to over 80% at present.

 

At present, the sales volume and sales volume of China's engineering machinery have surpassed that of the United States, Japan and Germany, ranking the first in the world. The self-sufficiency rate of engineering machinery in China has increased from about 70% during the tenth five-year plan period to over 80% at present. A large number of engineering machinery products, including loaders, excavators, automobile cranes, rollers, forklifts, bulldozers, and concrete machinery, have become the world's largest engineering machinery manufacturer. The rapid development of the machinery industry and the huge market scale have provided broad development space for the fastener industry.

 

China's machinery industry is the largest industrial sector in China. In 2011, the total industrial output of China's machinery industry reached 16.89 trillion yuan. Among them, imports reached us $283.023 billion, up 23.34 percent year on year. Exports totaled us $291.534 billion, up 24.83 percent year on year. The import and export trade surplus is us $8.511 billion.

 

International mold and metal plastic industry suppliers association secretary general luo hui pointed out that, in recent years, although the technology transfer, technical innovation, scientific research and development, etc., countries give some support, but compared with the current market demand and foreign level, there is still a big gap, specific displays in: product variety, low level of less, the quality is not stable, early high failure rate, poor reliability.

 

"Fasteners as a foundation for machinery industry main product, the development of mechanical industry, fastener products put forward higher requirements for" hundred hui thinks, at present domestic standard fasteners always exceeds the demand, and high-grade titanium fasteners, unique shape, high temperature plastic composite, special performance, such as fasteners in short supply, more dependent on imports. The national machinery agency listed "common standard fasteners" as a restricted development product, and "high strength heterogeneous fasteners" as a current encouragement for development. With the improvement of national industrialization level and technical progress, the usage of high strength fasteners increases gradually.

 

During the 12th five-year plan period, the number of loading machines, excavators, rollers and other engineering machinery products will reach 6 million, and the annual sales volume will be about 50,000. Therefore, it is estimated that the annual demand for high-strength fasteners is about 20,000 to 30,000 tons.

 

"Fasteners are not only the basic industry of China's equipment manufacturing industry, but also the important foundation of national economic construction." Luo baihui, secretary general of imoc, pointed out that during the 12th five-year plan period, while maintaining some cost advantages, the industry must rely on new advantages such as technological progress, quality improvement and cost performance of products to achieve sustainable development.

 

The total output of the whole industry is expected to reach 7.5 million to 8 million tons by the end of 2015. Under the overall situation of expanding export, the export products will grow in ups and downs. It is estimated that the average export growth rate during the 12th five-year plan period will be 8% to 10%, and the total export volume of the whole industry will reach 30 billion yuan by 2015. #p# page title #e#

 

The mechanical industry is one of the main users of fasteners. Due to China's late understanding of the important role of mechanical basic parts in the machinery industry and its lack of investment for a long time, the whole industry has a poor foundation, thin foundation and weak strength. Especially with the improvement of the level of the Chinese mainframe, the bottleneck phenomenon of mechanical infrastructure lagging behind the mainframe is increasingly apparent.
