With the rapid development of new energy vehicle technology, the automotive electrical architecture is developing towards integration, and the miniaturization of components has gradually become a trend. In this context, will the flat wire applied in the vehicle end be expected to usher in a new development outlet?
In 2023, China's automobile production and sales will both exceed 30 million units, a record high. The development of the new energy vehicle industry is even more rapid, with an export volume of 12030,000 units, a year-on-year increase of 776%。
With the continuous increase in the number of new energy vehicles, the iteration of technology is also changing with each passing day. The electrical architecture of automobiles will become more and more complex, and the future of in-vehicle space will be even more "every inch of land" - the small size and integration of on-board magnetic components are the general trend.
Under the miniaturization of magnetic components, what are the advantages of flat wire?
Driven by multiple demands, flat wire materials have become an effective solution to reduce the volume of magnetic components.
Compared to round wires, flat wires have a flatter cross-sectional shape and take up less space for the same conductor cross-sectional area, which can improve the compactness and integration of magnetic components such as inductors. On the other hand, the flat wire winding can replace the magnetic ring in the component, which reduces the overall volume of the magnetic element while reducing the overall loss and higher efficiency.
According to the data of China Electrical Industry Association, the demand for magnet wire in China will reach 1.8 million tons in 2020, and in the sector of electromagnetic flat wire, Ningbo Jintian Group is currently one of the few enterprises in China with a large-scale layout. Because it is more difficult to manufacture than ordinary wires, manufacturers concentrate on the head.
Since 1986, Jintian Copper has been focusing on copper processing for more than 37 years, and has profound experience in R&D and innovation in enameled wire and magnet wire. In 2022, they founded the "Electromagnetic Flat Wire Project for New Energy Vehicles", and planned to invest 400 million yuan for the 40,000-ton electromagnetic flat wire project for new energy vehicles, which will be constructed and operated by Jintian New Materials, a wholly-owned subsidiary. The infrastructure of the project has been completed in September 2023, and the first phase of equipment has been installed and tested and put into production.

* Full inspection system to ensure product reliability.
Under the iteration of high-end technologies such as in-vehicle Internet and intelligent driving, the demand for high-performance components continues to rise. Some terminal automobile manufacturers have also said that the current gap between domestic and foreign components is mainly reflected in consistency and reliability. As an important component of on-board magnetic components, the reliability of the wire also directly affects the operation of components and vehicles.
Although there are many advantages over round wire, flat wire has many advantages. However, compared with ordinary wires, the manufacturing process of flat wires is also more complex, the production process is more cumbersome, and it is necessary to use higher-end equipment and invest higher costs, which is a huge test for the company's production research and development and process control capabilities.
With 37 years of experience in the copper processing industry, Jintian's current production, R&D and process control capabilities have been at the first-class level. If you want to do a good job, you must first sharpen your tools. In the round line to flat wire project, equipment plays a primary role. The construction of new plants, the introduction of foreign high-end equipment, and the improvement according to the actual application needs are the first big steps taken by Jintian.
At present, whether it is round wire or flat wire production, we will use 100% ** inspection. According to Jintian, the traditional material production methods are mainly based on random inspection, while Jintian adopts the method of full inspection.
Our inspection is carried out in the MES system, which can play a full set of traceability functions. "The so-called full set of traceability functions refers to the entry of product-related information on the product. Product data can be stored for a long time, once a product problem is found, you can trace which link in the production process is wrong by scanning the way.
Such a full set of traceability system is more applied to automotive terminal parts enterprises, in order to find problems faster, quickly recall and rectify, and improve the efficiency of the entire production line. At present, on the material side, Jintian is one of the few leading enterprises to adopt this system, which further ensures the accuracy and reliability of product production.
15 years of experience senior team, for high-quality service endorsement.
In addition to high integration and high reliability, customized services are another important demand for new energy vehicle components in the future. In the field of automotive wires, the R&D team equipped by Jintian is a team of engineers with more than 15 years of experience in the industry.
The experienced R&D team represents the ability to quickly identify and solve problems, the ability to execute efficiently, and innovative ideas with forward-looking recommendations. This provides strong talent support for Jintian to design and verify together with customers in the flat wire project and find the most suitable processing method.
It is the strong R&D team and technological innovation strength behind Jintian that endorses the product quality. As a leading group in the copper industry, Jintian has also been recognized as a national enterprise technology center, and has successively set up a special national R&D center, an international postdoctoral research workstation and a CNAS-certified R&D laboratory.
With lean production and lean management, as well as many years of service in the automotive product chain, Jintian's customers include many well-known foreign and leading automotive customers, and the scope of cooperation includes automobile OEMs and various component manufacturers.

Multi-track layout, bravely compete for the first brand of flat line.
The application of magnet wire covers all walks of life, and the future development space is broad. In terms of electromagnetic flat wire, the total production capacity of Jintian flat wire products has reached 30,000 tons, and the next goal is to release the production capacity to more than 60,000 tons, mainly for new energy vehicles and consumer electronics.
Magnet wire is a basic material, and it can be found in basically all components that can be turned. "According to the market development trend, Jintian said that it has begun to enter photovoltaic and other emerging fields, and flat wire products will gradually expand in this direction in the future."
As a leading copper processing enterprise in China and ranked among the top 500 Chinese enterprises, Jintian's goal is certainly much more than that.
To be the first brand of flat wire in China's magnet wire industry" is the blueprint that Jintian is committed to depicting.
