Ministry of Industry and Information Technology issued the "Twelfth Five-Year" development plan for the "three basics" industry

Recently, the Ministry of Industry and Information Technology issued the “Twelfth Five-Year Development Plan for the Basic Manufacturing Process and Basic Materials Industry of Mechanical Basic Parts”. The plan implements the spirit of the Twelfth Five-Year Plan for National Economic and Social Development and the Industrial Transformation and Upgrading Plan (2011~2015), and summarizes and analyzes the development of mechanical basic components, basic manufacturing processes and basic materials industries. On the basis of the status quo, the development goals and ideas of the “Twelfth Five-Year Plan” were clarified, the key points and main tasks of the industrial development were determined, and relevant safeguard measures were proposed. The implementation of the plan will further enhance the overall development level and international competitiveness of China's mechanical basic parts, basic manufacturing processes and basic materials industry.

Mechanical basic parts, basic manufacturing processes and basic materials (hereinafter referred to as “three basics”) are the basis for the survival and development of the equipment manufacturing industry. The level directly determines the performance, quality and reliability of major equipment and host products. Mechanical basic parts are the basic units that make up the machine and cannot be separated, including: bearings, gears, hydraulics, hydraulic components, pneumatic components, seals, chains and sprockets, drive couplings, fasteners, springs, powder metallurgy parts , the basic manufacturing process refers to the casting, forging, heat treatment, welding, surface engineering and cutting processing and special processing technology with large volume and versatility in the production process of the mechanical industry; the basic materials are specifically required for the mechanical manufacturing industry. Small batch, special high quality special materials.

High-strength fasteners are the focus of development
10.9 and above automotive engine fasteners, large-scale high-strength fasteners for wind power generation equipment, aluminum-magnesium alloy fasteners for aircraft and spacecraft, self-locking fasteners.

Development status and situation
After years of hard work, China's "three basics" industry has made great progress, forming a production system with complete categories and meeting the general needs of the host industry, providing an important support and guarantee for the development of the equipment manufacturing industry.

The scale of the industry continues to expand. In the past ten years, China's “three-based” industry has continued to grow steadily, and the variety and level of products have been greatly improved. The output (output value) of various common mechanical basic parts is among the highest in the world; casting, forging, welding, heat treatment and cutting processing capabilities The production of basic materials such as welding materials, high-speed steel, hard alloys, NdFeB permanent magnets ranks first in the world.

The ability to set is constantly increasing. The average domestic market share of mechanical basic parts such as bearings, gears and fasteners is 65%. Significant progress has been made in the basic manufacturing process, and a large number of large castings and forgings for power generation equipment have the ability to enter the international market. Focusing on the needs of electrical and electronic equipment, we have developed special high-quality special materials such as steel for power generation equipment and oriented silicon steel sheets for large transformers.

The aggregation effect is obvious. The output value of Wenzhou, Ningbo, Haiyan and Weinan's four fastener industry clusters accounted for 67% of the national fastener industry. The level of specialization in basic manufacturing processes has been continuously improved. A number of high-level, specialized basic manufacturing process centers have been built in major equipment manufacturing clusters. For example, the output of precision forgings in Jiangsu Taizhou and Dafeng exceeds half of the national precision forgings.
