In the automotive manufacturing system, stamped and welded parts occupy a crucial position. In modern automotive manufacturing processes, 60% to 70% of metal parts are formed through stamping, with an average of over 1,500 stamped parts per vehicle. These parts are widely used in body panels, interior support components, structural reinforcements, and critical components such as engine exhaust pipes, oil pans, engine mounts, and crossbeams. With the rapid increase in the penetration rate of new energy vehicles and the accelerated pace of model upgrades, the automotive stamping and welding parts industry is facing profound structural changes.
Industry Status: Market Size and Competitive Landscape
The booming development of the automotive industry has effectively driven market demand for stamped and welded components. According to statistics from the China Association of Automobile Manufacturers, my country's automobile production and sales increased by 3.4% and 3.8% year-on-year in 2021, ending three consecutive years of decline since 2018; in 2022, production and sales continued to grow by 3.4% and 2.1% year-on-year, respectively. According to calculations by Minsheng Securities Research Institute, based on the 2021 automobile production of 26.082 million vehicles, the market size for automotive stamping parts in my country reached approximately 260.9 billion yuan that year.
With the continuous growth in automobile production and sales, the automotive parts market, located upstream in the industrial chain, continues to improve. At the same time, the ever-growing number of vehicles also implies considerable demand for parts replacement. As an important component of parts, the automotive stamping parts market has broad prospects. It is worth noting that in this industry, Copper Pressed Components are widely used in various electrical connection and switching systems, and their stamping precision is directly related to the reliability of automotive electronic modules.
Currently, the domestic automotive stamping parts market is characterized by non-standard customization and long R&D cooperation cycles. Automotive stamping parts are diverse in type and vary depending on different car models, technologies, and performance requirements. The production process necessitates in-depth communication and cooperation with downstream customers, resulting in highly non-standard products. Due to this characteristic, automotive stamping parts exhibit a clear "production-to-order" model in their production and sales. In the field of conductive stamping parts, Electrical Rivet Connection Solutions provides highly reliable electrical connection solutions for automotive relays, switches, and other components by precisely riveting silver contacts to copper terminals.
Market Opportunities: New Energy Vehicles Create Structural Growth
As the penetration rate of new energy vehicles in the overall vehicle market continues to increase, the demand for stamped parts is also rising steadily. According to statistics from the China Association of Automobile Manufacturers, my country's new energy vehicle sales reached 6.887 million units in 2022, with the market penetration rate rapidly increasing from 13.4% in 2021 to 25.6%. Compared to traditional fuel vehicles, new energy vehicles are not only active practitioners of lightweight vehicle bodies, but their new energy power system model also brings incremental demand to the industry chain.
In the above applications, many electrical connection components need to balance conductivity and mechanical strength. Copper Stamping Parts With Riveted Silver Contacts, by riveting silver-based contacts to copper stamped parts, significantly improves the contacts' resistance to arc erosion while maintaining high conductivity. Similarly, Silver Contact And Copper Stamping Riveted Parts uses a cold riveting process to achieve reliable connections between dissimilar metals, avoiding the risk of incomplete welds that may occur with traditional brazing. These processes are crucial for key components such as relays, switches, and connectors in automotive electrical systems.
Looking ahead, vehicle body structural components need to simultaneously meet the requirements of high strength and impact resistance. For a considerable period, high-strength steel stamping or high-strength aluminum stamping/extrusion processes are expected to remain the mainstream. Stamping technology is widely used in vehicle body structural components and has significant advantages: stamping materials can cover steel, aluminum, and magnesium, and seamless switching between steel and aluminum is possible; at the same time, stamping processes produce products with high consistency, high strength and rigidity, and relatively low cost.
Outlook: Stamping Remains the Mainstream Technology for Automotive Structural Components
Looking ahead, stamped and welded parts will remain the mainstream choice for automotive structural components for a considerable period. The advantages of stamping in body structural components are irreplaceable: high-strength steel stamping meets core requirements for strength and impact resistance; aluminum stamping/extrusion provides a feasible path for lightweighting; and the stamping process itself possesses the combined advantages of high consistency, high rigidity, and low cost.
Meanwhile, with the continuous increase in the electronic content of automobiles, the demand for precision stamped parts such as Copper Stamping for Switches will continue to grow. From relay bases to power distribution units, from lighting control modules to battery management systems, high-quality copper stamped parts and reliable contact riveting processes together form the underlying foundation of automotive electrical connections. Embedded Riveted Electrical Contacts technology can simultaneously rivet multiple contacts on a single copper stamped part, with the relative positions of each contact guaranteed by die precision, requiring no subsequent adjustments, making it particularly suitable for multi-circuit control modules. In-Die Riveted Silver Contacts take this technology to a higher level of integration, simultaneously completing the feeding, positioning, and riveting of silver contacts within the mold, representing the cutting-edge direction of automotive electrical stamping parts manufacturing.
