As China's auto industry continues to grow, the auto parts industry continues to improve. However, in the areas of key components with high technological content, such as EMS engine control systems, airbags, ABS systems and other systems and components, the competitiveness of local parts and components companies is still not strong.
The survey shows that China’s auto parts companies’ R&D investment currently accounts for only 1.4% of sales revenue, far below the average of 5% for multinational companies. Due to the low level of research and development, there is no independent brand, and it is only possible to imitate the production of other people's products. As a result, domestic parts and components companies do not have the right to speak in the market and they are vulnerable to vehicle companies.
Practically speaking, the development of multinational corporations in China has now shifted from merely pushing products, propagating brands to pushing practical technologies, and moving from purely supporting vehicles to marketing designs, and entering a new strategic stage. This makes long-term adherence to vehicle companies, and the challenges facing China's auto parts industry, which are obviously at a disadvantage, such as capital, technology, management, and research and development, are even more severe.
The autonomous zero automotive parts industry faces challenges. Xu Changming, director of the Information Resources Development Department of the National Information Center, believes that, first of all, with the constant rise in factor prices, the cost advantage of independent components is being weakened, and foreign-funded parts companies rely on the advantages of scale and the localization of R&D to create a clear cost advantage. Secondly, standards for energy conservation and environmental protection have been tightened and regulations tightened, bringing double pressure on technology and costs to independent components and parts. Third, the popularity of modular production and simultaneous development has brought higher and higher technical barriers to autonomous parts and components.
Without first-class automotive parts technology, it is impossible to build a first-class vehicle. In the entire automotive industry chain, auto parts have a one-third share, especially the profits of high-end parts and components are even higher than that of the entire vehicle company. If auto parts technology is improved and independent innovation results are significant, then vehicle technology will also develop simultaneously.
Galvanized steel coil is a material produced by continuous hot-dip galvanizing process with hot-rolled steel strip or cold-rolled steel strip as the substrate. Hot dip galvanized coil supplied in coil form after coiling. Therefore, galvanized steel sheet (coil) can be divided into hot-rolled galvanized sheet coil and cold-rolled hot-dip galvanized sheet coil. They are mainly used in the fields of construction, household appliances, automobiles, containers, transportation and household industry. Especially in steel structure construction, automobile manufacturing, steel warehouse manufacturing and other industries. Their main characteristics are: strong corrosion resistance, good surface quality, benefit from deep processing, economy and practicality, etc.
Galvanization is the leading method to protect metals from environmental elements that cause corrosion, rust, and the eventual weakening of the steel. Hot-dip galvanizing deposits a thick, robust layer of zinc iron alloys on the surface of a steel item.When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide which further reacts with carbon dioxide to form zinc carbonate. A dull, grey, fairly strong material that stops further corrosion in most circumstances, protecting the steel from the elements. Galvanized steel is widely used in applications where rust resistance is needed. Galvanized steel is commonly used in the automotive industry to enhance the corrosion performance of exterior body parts. Galvanized Steel is magnetic.
