The development status of fasteners in 2016


The global economy continues to weaken, overseas export trade depression, many fastener enterprises both at home and abroad, is facing a severe test.Accelerate the economic transformation and structure upgrade is imminent, to develop overseas market is undoubtedly the current fastener industry development of important ways.

From the fourth quarter of 2011 to the first half of 2012, the influence of the objective environment, fastener industry development speed or will slow, but since the third quarter of 2012, as the policy in place, the eighteenth big meeting, and the upcoming series of development policy, etc., can promote the further development of the industry.And must adhere to innovation and restructuring, will continue to closely rely on cars, new energy, aerospace, shipbuilding, urban traffic, IT, electronic appliances, construction and other key industries, accelerate the fastener product optimization and upgrading, promoting the healthy and steady development of fastener industry.

According to the China fastener industry transformation and upgrading of production and marketing demand forecasting and analysis report preview "statistics: global fastener market size of more than $50 billion, 2012 Chinese fasteners production also is expected to reach 6.8 million tons.But compared with the United States, Japan and other manufacturing powerhouse, fastener industry of our country there is a big gap.

Mechanical industry

Machinery industry is a major one of the users of fasteners.Due to China for a mechanical components in the important position in the mechanical industry know late, lack of long-term investment, and the poor, poor foundation, weak industry foundation.Especially as China to raise the level of the host machine foundation behind the host becomes increasingly bottlenecks.Today, 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, also put forward higher request of fastener products.Domestic standard fastener has been oversupplied and high-grade fasteners (high temperature, special shape, titanium compound, specific performance and other fasteners) in short supply, more dependent on imports.National okmo limit "common standard fastener" as development products, "high strength" "encourage the development of current products.High strength fasteners, with the improvement of national industrialization level and technological progress, gradually increase usage.

High strength automobile fasteners

The visit and survey the 13 domestic automobile fasteners company, companies have been surveyed through TS16949 system certification.About 1500, an average of 1 cars fasteners bolt for the total time of each car is about 2.5 ~ 3.2 h.The type and quality of visible fasteners has important influence on the quality of the host level and vehicle.In this paper, from the process of production of high strength thread fasteners, localization of high strength thread fasteners and supplier quality management is analyzed.

High strength thread fasteners products process

High strength of threaded fasteners production process for raw material restructuring - cold heading forming - thread processing (thread rolling or rub silk) to heat treatment and surface treatment, sorting, packaging, 10.9 magnitude generally adopts the thread rolling process after heat treatment.

Auto fastener materials

High strength bolts used steel grades of 8.8 bolt with 35 steel, 45 # steel, ML35 steel;10.9 with 35 crmo bolts;40 cr;12.9 bolt with 35 crmo, 42 crmo, SCM435.

Basic raw materials used in domestic fastener is hot rolled state, while the production of fasteners, such as the Japanese steel is basically can cold heading directly state, users need not pretreatment, can reduce cost from the link.

Common failure forms of fastener failure have assemble stretch, fatigue fracture and delayed fracture.
