The Ministry of Industry and Information Technology will vigorously promote the development and application of special aluminum materials in the automotive and other fields

On August 25, the Counselor's Office of the State Council and the China Non-Ferrous Metals Industry Association jointly organized the “High-Level Forum on Promoting Aluminum Applications” in Beijing. The theme of the forum was “To enhance the application capabilities of China’s aluminum industry, promote energy conservation and emission reduction, and promote China’s aluminum industry. healthy growth". State Councilor and Secretary General of the State Council Ma Kai, Vice Chairman of the Tenth NPC Standing Committee and Honorary Chairman of China Nonferrous Metals Industry Association Sheng Huaren, Minister of Industry and Information Technology Miao Wei, Director of State-owned Assets Supervision and Administration Commission Wang Yong, Director of State Department Counselor Chen Jinyu and Development Leaders of the Reform Commission and the State Council Research Office attended the opening ceremony of the forum. More than 350 representatives from relevant ministries and commissions of the State Council, the Chinese Academy of Engineering, local governments, key enterprises in the aluminum industry, research institutes, relevant industry associations, relevant international organizations, and embassies of some countries in China attended the conference. Ma Kai and Miao Wei made speeches.

Ma Kai pointed out that the raw material industry is the foundation of industry and an important part of the national economy. Since the reform and opening up, the raw material industry has achieved rapid development, but it also faces deep-seated contradictions and problems. It is necessary to thoroughly implement the scientific concept of development and use global perspectives. Strategic thinking and long-term vision, correctly analyzing the development situation of the raw material industry, scientifically formulating development strategies, persisting in the road of new industrialization, stabilizing growth, transferring methods, adjusting structure, and accelerating the transformation of China from a big raw material country to a powerful raw material country.

Miao Wei pointed out that promoting the application of aluminum and expanding market demand is an urgent need to respond to the current severe economic situation, and it is also an important guarantee for promoting the stable and rapid development of the aluminum industry. The Ministry of Industry and Information Technology attaches great importance to and takes measures to promote aluminum applications. Guide and support the industry-wide development of special materials in the automotive, aerospace, shipbuilding, rail transportation, defense technology, industrial, and other fields, focusing on lightweight, high-strength, large-size, high-temperature, and corrosion-resistant, and vigorously develop high-quality intellectual property Performance aluminum alloy and its deep-processed products and processes. Accelerating the implementation of high-precision product engineering, relying on competitive enterprises, industrial clusters and major projects, accelerating the industrialization of new technologies such as high-end aluminum materials and large-scale manufacturing, extending the industrial chain, and developing aluminum deep processing components, striving to meet strategic emerging industries and countries Major engineering needs.

Mechanical properties of injection connector fittings as far as connection functions are concerned, insertion and extraction forces are important mechanical properties. Plug force is divided into insert force and pull out force (pull out force is also called separation force), the requirement of both is different. In the relevant standards, there are provisions for maximum insertion force and minimum separation force, which indicate that, from the point of view of use, the insertion force should be small (hence the structure of LIF with low insertion force and ZIF without insertion force), and if the separation force is too small, it will affect the reliability of contact.
Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a kind of durability index, which is called mechanical operation in GB5095. It is based on a cycle of one insert and one pull, and whether the connector can normally complete its connection function (such as contact resistance) after the specified plug cycle. The plug force and mechanical life of the connector are related to the plating quality (sliding friction coefficient) of the contact part of the contactor structure (positive pressure size) and the dimensional accuracy (alignment) of the contactor.
