In the dust-free workshop of Tongling Jingda Special Magnet Wire Co., Ltd., a spool of magnet wire with a diameter of only 0.018 millimeters is being rapidly wound — about 1/20 the thickness of a human hair, yet capable of withstanding temperatures up to 300°C and voltages of 30,000 volts. On July 4th, the 2025 "Research Tour on Vibrant China" Anhui themed interview group witnessed another world first made in Anhui's intelligent manufacturing — a 35% share of the global market, making this company the undisputed leader in the magnet wire industry.

Currently, Jingda has obtained 356 invention patents, and its products are certified by international companies such as Tesla and BMW, extending from traditional home appliances to emerging sectors like new energy vehicles, photovoltaic inverters, robots, drones, and maglev transportation.

“The weight deviation per kilometer does not exceed 0.1 grams. Last year’s output of 350,000 tons could circle the earth 180 times,” explained Qin Bing, General Manager of the company. Following a “focus on high-end” strategy and jointly building 20 R&D platforms with Shanghai Jiao Tong University, the flat wire used in new energy vehicles alone has generated 4 billion yuan in revenue. AGV driverless vehicles shuttle materials, rooftop photovoltaic installations reduce carbon emissions by 8,600 tons annually, and the digital platform improves efficiency by 30%. The company has won titles such as "Manufacturing Single Champion Demonstration Enterprise" by Chinese authorities, signaling a new vitality for traditional manufacturing.

As the only city in the province with a complete copper industry chain, Tongling has formed seven complete industrial chains with an output value reaching 71.9 billion yuan in 2024. From Tongling Nonferrous Metals’ world-class electrolytic copper to Jingda’s global leadership in magnet wire, this “Ancient Copper Capital of China” is transforming traditional advantages into new momentum for high-end manufacturing. In the packing area, magnet wire marked with the destination “Germany” is ready to ship — this fine wire “smartly made” in Tongling, Anhui, is about to embark on a new global journey.
