Where are the mechanical fasteners?

Machinery industry is one of the most important users of fasteners, but due to China's relatively late recognition of the importance of mechanical parts in the machinery industry, long-term lack of investment has resulted in a poor foundation, weak foundation, and weak strength. In particular, with the increase in the level of China's host computer, bottlenecks that mechanical components lag behind the host are becoming increasingly apparent.

In recent years, although the state has given certain support in the aspects of technology introduction, technological transformation, and scientific research and development, there is still a small gap compared with the current market demand and foreign standards. The specific manifestations are: low product varieties and low levels. , The quality is unstable, early failure rate is high, and reliability is poor.

At present, China's machinery parts and components manufacturing enterprises have grown to over 1,000, but most of the products have low technological content and cannot enter the mainstream market for key components. It is expected that China's mechanical fastener enterprises will present a clustered development in the future. That is, the mechanical fastener companies of similar neighboring enterprises are gathered together and led by the Local Mechanical Fasteners Association to gain a competitive advantage through continuous innovation. It is the characteristic private small and medium-sized enterprises that play an important role in the clustering of mechanical fastener products. They rely on leading enterprises to carry out OEM production. And in a special field, both competition and cooperation gradually form an industrial chain.

To "high-end" read fasteners as the main part of the mechanical industry products, the development of the machinery industry, but also put forward higher requirements for fastener products. At present, domestic common standard fasteners have been oversupply, and high-grade fasteners (high temperature, special-shaped, titanium-plastic composite, and special-performance fasteners) are in short supply, and they must be imported. The State Bureau of Machinery classified "ordinary standard fasteners" as restricted development products and "high-strength special-shaped fasteners" as currently encouraged development products. High-strength fasteners With the improvement of the industrialization level and technological progress of the country, the usage has gradually increased.

The expectations of the machinery industry for the development of fasteners and the improvement of their performance are more pressing. With the enlargement of large-scale technical equipment and the limitation of parameters, it is necessary to develop more new types of fasteners that are resistant to high temperatures, high pressure, and radiation and corrosion resistance.

Informatization speeds up. With the further expansion of the market competition of mechanical fasteners enterprises, the emergence of management ideas on how to effectively use and manage the company's overall resources will be followed by the development of enterprise information through the ERP computer network system to integrate enterprise logistics, capital flow, and information flow. The core idea of ​​management is to realize the management mechanism of "supply chain" management. Real-time and accurate grasp of the pulse of market demand, support for enterprise grouping, cross-border operations, its main purpose is to fully allocate and balance the company's resources in all aspects, suitable for global economic integration, diversified customer needs, product production cycle Shortening, fierce market competition, such an environment. This enables companies to play their full potential in a fierce market competition and enable them to achieve better economic benefits.

The leader in the well-known Chinese machinery industry will increase the research and development of parts and components. In the field of construction machinery, industrial organizations such as the Construction Machinery Industry Association also intends to let several major machine companies take the lead in forming technology alliances to carry out technical research on key components.

The national competent authorities will gradually increase their support for parts and components. According to the latest documents from the Ministry of Industry and Information Technology, wind turbine generator bearings, generator bearings and main shaft bearings, gear transmissions for over 1.5 MW wind turbines, hydraulic servo systems and sealing systems for yaw pitch change, and wind turbine towers Specifications High-strength Fasteners, Blade Forming Dies, Large precision stamping dies for motor stator and rotor parts, Large-scale hydro-generator ball valves, Runner blades, Servo-membrance sealing systems; Secondary pump bearings for nuclear power plants, New nuclear power main pump tertiary sealing devices High-reliability fasteners for nuclear power, etc. will be supported in the future.

Broad market prospects According to the "Twelfth Five-Year Plan for the Development of Machinery Industry," the machinery industry must maintain steady and healthy development during the 12th Five-Year Plan period, and the average annual growth rate of total industrial output value, industrial added value, and main business income should be maintained at 12 Around %, the growth of high-end equipment is more than double the average growth rate of the industry. At present, the supply and demand trends in the machinery industry are generally stable, but the supply and demand situation in each specific sub-sector will be further divided.

High-end CNC machine tools, offshore heavy equipment, precision basic parts, transmission and transformation equipment and electrical automation equipment and other machinery sub-sectors are difficult to shorten due to their own high technical barriers and production cycle, resulting in limited capacity increase, and power grid construction, new energy development The acceleration has also led to a substantial increase in downstream demand, so the performance of downstream demand is growing at a faster pace than supply growth. The demand for fasteners in these industries remains strong.

Although there was no significant increase in production capacity in machinery sub-sectors such as textile and garment machinery, packaging machinery, metal abrasives, and power equipment, due to the obvious downturn in the downstream industries, the demand was shrinking, resulting in a situation in which the supply exceeds demand. Demand has dropped.

In the field of agricultural machinery, the total output value of a series of agricultural machinery products such as tractors, rice transplanters, and harvesters will reach 250 billion yuan during the 12th Five-Year Plan period. It is estimated that annual demand will be over 150,000 tons of various types of fasteners and the output value will be about 2 billion yuan.

In the field of construction machinery, the social possession of construction machinery loaders, excavators, road rollers and other products will reach 6 million units during the “12th Five-Year Plan” period, with an annual sales volume of around 50,000 sets. It is expected that annual demand for high-strength fasteners will be 2 - 3 million tons.
