Fasteners are used as fastening connections and are widely used in a class of mechanical parts. Various types of fasteners can be seen in a variety of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. It is characterized by a wide variety of specifications, performance purposes vary, and standardization, serialization, generalization of the species is also very high.
Fasteners are the most widely used mechanical foundation pieces. With China's accession to the WTO in 2001 and entered the ranks of international trade power. China's fasteners a large number of products exported to countries around the world, the world's fastener products are also constantly influx of the Chinese market. Fasteners as one of China's large imports and exports of products, to achieve international standards, to promote China's fastener enterprises to the world, to promote the full participation of fastener enterprises in international cooperation and competition, have an important display and Strategic significance. A fastener is a generic term for a class of mechanical parts that are used when two or more parts (or components) are fastened together.
Fasteners as the main machinery industry, the basic parts of the product, the development of machinery industry, but also on the fastener products put forward higher requirements. Domestic standard fasteners have been oversupply, and high-grade fasteners (high temperature, shaped, titanium plastic composite, special performance and other fasteners) in short supply, but also rely on imports. National Machinery Bureau to "ordinary standard fasteners" as a restricted development products, "high-strength special-shaped fasteners" as the current encourage the development of products. High-strength fasteners with the national level of industrialization and technological progress, the use of gradually increased.
To fasteners as the representative of the basic pieces, not only China's equipment manufacturing industry, the basic industry, but also an important basis for all areas of national economic construction. During the second five, the industry to maintain part of the cost advantage at the same time, must rely on technological progress, quality improvement and product cost and other new advantages to achieve sustainable development. It is expected that the total output of the whole industry will reach 7.5 million to 8 million tons by the end of 2015. In the general situation of expanding exports, the export products will show a fluctuating trend. The average annual export growth rate is expected to be 8% ~ 10% , By 2015 the total export industry will reach 30 billion yuan.
