Analysis of the current market situation of fasteners, light weight and high strength are the development directions.
Fasteners are the most widely used mechanical basic parts, which are widely used in automobile, energy, electronics, electrical appliances, machinery and other industries. All kinds of fasteners can be found in various mechanical equipment, vehicles, ships, railways, bridges, buildings, instruments and meters, etc. Among them, automobile is the largest application field of fasteners, accounting for 23.2%, followed by maintenance industry and construction industry, accounting for 20%, and the third market is electronic industry, accounting for 16.6%.
The growth rate of demand for fasteners in my country is 5%-10%. In 2008, the demand for fasteners was 3.13 million tons, an increase of 9.5% year-on-year. Among them, the automobile industry is the largest user, followed by the maintenance industry market and construction industry, and then electronics industry. Recently, in order to stimulate domestic demand, the state has issued a number of policies to support the manufacturing industry. In the government's 4 trillion yuan investment plan, the focus is on the construction of railways, highways, airports, power grids, and affordable housing infrastructure. The most direct beneficiaries are equipment. Manufacturing industry, which will greatly stimulate the demand for fasteners. In particular, the demand for high-strength fasteners with a specification of 1630mm ≥ 10.9 will increase sharply. In addition, the development of the aviation industry has also played a strong supporting role in the demand for fasteners. For example, Boeing plans to add 3,400 new aircraft in the next 20 years. This data will bring new development and demand opportunities for the fastener industry.
Fasteners are the most widely used basic components in industry today, and are known as "industrial rice". Fasteners are characterized by a wide variety of specifications, different performances and uses, a high degree of standardization, serialization, and generalization, and a wide range of applications, involving many sectors of the national economy. They are widely used in various machinery, equipment, vehicles, ships, Railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and other products. The prosperity of the above-mentioned main application industries is high, and the demand for fasteners is large, which will further stimulate the expansion of the production capacity of fastener enterprises. The technological progress and industrial upgrading of the main application industries will further increase the requirements for the performance and quality of fasteners. Promote the advancement of the technical level of the fastener industry and promote the improvement of the quality of fastener products; the development of new application fields will expand the market demand for fasteners and promote the diversification of fastener products. In recent years, the entire fastener industry in my country has basically maintained a steady and steady growth. Generally speaking, due to the slowdown in global economic growth and the increasing downward pressure on the domestic economy, the growth in downstream demand for fasteners has slowed down, especially The low-end production capacity of domestic fasteners is seriously overcapacitated, but the supply of high-end products is insufficient, and the fastener industry has shifted from high-speed growth to high-quality growth.
Can standard parts be used in that way? In fact, standard parts are a type of mechanical parts that are used for fastening connections and are widely used. All kinds of fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. It is characterized by a wide variety, different performances and uses, and the degree of standardization, serialization, and generalization is also extremely high. Therefore, some people also refer to a class of fasteners with existing national standards as standard fasteners, or simply as standard parts. Fasteners are the most widely used basic mechanical parts. With my country's accession to the WTO in 2001, it has entered the ranks of international trade powers. Construction fastener T-bolt
With the development and progress, the quality of its industrial demand is getting higher and higher, so the requirements for fasteners are also increasing. High-strength fasteners can meet everyone's needs. At present, the development prospects of high-strength fasteners are good. However, there are still some problems with domestic high-strength fasteners. According to our understanding, there are mainly the following major problems.
At present, the most commonly used standards in our daily business are as follows:
High-strength bolts are high-strength bolts and belong to a standard part. In general, high-strength bolts can withstand a larger load than ordinary bolts of the same specification.
