Guangzhou, January 24, 2022 -- The electric vehicle market is growing rapidly with an unstoppable trend. In 2021, the production and sales of new energy vehicles respectively completed 3.545 million and 3.521 million units, an increase of 1.6 times year-on-year, and the market penetration rate reached 13.4%. It can be said that China's automobile industry has entered the electrization stage The Times.
With the advent of automotive lightweight era, integral die casting has great potential
Compared with traditional fuel vehicles, new energy vehicles pay more attention to the development of lightweight vehicles for the consideration of endurance. In addition to the application of new materials, the manufacturing process of automobile parts has also begun to play an increasingly important role in reducing the weight of automobiles, among which the integral integration of parts (also known as integral die casting) is one of the important directions of efforts of major new-energy automobile manufacturers.
For example, Tesla, the global leader of new energy vehicles, announced in September 2020 that the Model Y would adopt an integrated die-cast rear floor assembly, which can reduce 79 parts and reduce the manufacturing cost by 40%. Tesla also announced plans to use two to three large die-casts to replace the entire 370 parts of the vehicle, reducing its weight by a further 10% and increasing its range by 14%.
The electric coupe eT5 of China's new car maker Nio also adopts the integral die casting process. Compared with the "stamping + welding" process of traditional body manufacturing, the application of this new process makes the mileage of the electric coupe eT5 reach 1000 kilometers in the future. The four-piston aluminum alloy integral casting caliper also reduces the braking distance of the car from 100 kilometers to zero to 33.9 Rice, while the starting price has dropped to 328,000. Compared with the traditional "stamping + welding" process has great advantages.
Some people in the industry believe that the traditional body manufacturing process is carried out in accordance with the process of stamping, welding, coating and final assembly. A car is welded by about 500 parts with different shapes and materials. Each part has errors, and the error fluctuation of each part will affect the final body accuracy. The integral die casting body is the upgrade of lightweight technology. This process not only greatly reduces the number of body parts, greatly simplifies the body structure, but also simplifies the supply chain links, improves the utilization rate of raw materials, reduces the plant area and other advantages, and greatly improves the assembly efficiency of vehicles. In addition to reducing weight, components, and costs, an integral die cast body can also improve vehicle safety because it is made entirely of metal, so the direction of force is not an issue.
Eontec is a significant advantage of the first layout
At present, the A-share listed Eontech (300328.SZ) is one of the best enterprises in the field of light alloy material integration in die casting. It is reported that Eontech has been committed to the research and development of new lightweight materials and lightweight processes for new energy vehicles for a long time. Eontech is one of the first enterprises in the world to lay out large aluminum and magnesium alloy die casting equipment, and has great advantages in the integrated molding of large parts for new energy vehicles. With outstanding research and development strength and industrial application ability, Eontech not only has a post-doctoral research workstation, but also has been rated as one of China's top 50 die casting manufacturers with comprehensive strength.
Eontec's advantage in one-piece die casting also comes from its strong equipment advantage. It is understood that EON Technology and its holding subsidiary Chaohu Yian Yunhai have a variety of large die casting machines of 4200T, 3500T, 2700T, 2200T, 1800T, 1650T, 1400T and other models, which can meet the production needs of different specifications of large-scale precision die casting integrated products. In addition, Eontech will combine the market development and the actual needs of customers' products, and jointly develop and order the die-casting integrated molding equipment with a tonnage of 6000T or above. In the future, it can better integrate the parts of new energy vehicles and realize a wider application in large automobile die-casting products.
It is understood that, relying on the accumulation of more than 20 years of experience and technology precipitation in the precision die casting industry, Eontec's integrated die casting products have been widely used in the automotive field of automotive steering system, transmission system, door, seat, instrument panel support, as well as new energy vehicle motor, electric control, battery pack and other parts products, in addition, the company can also provide customers with molds Design and development, die casting, finishing, surface treatment, testing, packaging and other technology one-stop service. With excellent products and services, Eontec has entered the supply chain of well-known customers at home and abroad, such as Tesla, BYD, Ningde Times, Geely, Bosch, TKP, HBA, TRW, GKN, JAC, LG, Fochia, Continental, Alpe, etc., and its terminal customers cover a variety of mainstream brand cars.
In addition to automobiles, Eontec's products are also widely used in consumer electronics, communication equipment, LED supports, intelligent robots, medical equipment and other fields, and its customers include Amazon, Lenovo, Siemens, ZTE, Mindray Medical and many other well-known enterprises.
In general, integrated die casting is still in the introductory stage, with fewer models applied. However, as Tesla, Nio and other large manufacturers of new energy vehicles take the lead in adopting the technology and have obvious advantages, it is believed that more automobile enterprises will apply this technology in the future. If integrated die casting can be fully promoted, the market space will be huge, and the future prospect is worth looking forward to.
