On January 2, 2026, Jinggong Technology successfully developed and put into operation its first high-performance carbon fiber precursor production line with an annual output of 5000T! This marks the successful breakthrough of Jinggong Technology in the field of high-end carbon fiber raw silk equipment, taking a key step towards localization, scale and independent controllability.

Overcoming difficulties and successfully developing equipment for carbon fiber raw silk

This production line adopts the core technology independently developed by Jinggong Technology, and adopts a synchronous promotion mode of civil construction and equipment customization from the beginning. It completes a total of 30 individual buildings and off-site projects in three batches, demonstrating Jinggong Technology's excellent equipment turnkey project delivery capability.

During the equipment installation phase, facing the complex pipeline laying and installation and commissioning tasks of thousands of instrument valves, the company's technical team worked closely together to complete equipment positioning and pipeline integration with millimeter level accuracy, achieving a full chain closed-loop from technology research and development, equipment manufacturing to precise response, ensuring the successful one-time operation of the entire line, and providing a replicable engineering example for the industrialization of high-performance carbon fiber raw materials in China.

Leading by technology, establishing a benchmark for domestic raw silk equipment

The successful development of the 5000T high-performance carbon fiber precursor production line embodies the technical accumulation of Jinggong Technology in the field of carbon fiber for more than ten years. As a domestic provider of high-end equipment system integration solutions for the entire carbon fiber chain, Jinggong Technology has been laying out its carbon fiber business since 2013, establishing a national level carbon fiber equipment product research and development center. In 2020, it achieved a breakthrough in the national production of carbon fiber equipment, undertaking more than 50 carbon fiber production lines and maintaining its market share at the forefront of the country and the world.

This production line adopts the one-step process technology independently developed by Jinggong Technology, which greatly simplifies the process, shortens the workflow, and significantly improves the quality of PAN fibers. Among them, the conversion rate of polymerization reaction reaches over 90%, with few side reactions and good uniformity of molecular weight distribution, laying a solid foundation for the stable production of high-performance carbon fiber precursor. The spinning process adopts advanced dry spray wet method and steam high magnification stretching technology, with high fiber density and spinning speed up to 200-400m/min.

Technological independence empowers the carbon fiber industry for new upgrades

The successful development and smooth operation of high-performance carbon fiber raw material equipment this time will effectively fill the technological gap in this field in China, becoming another important milestone for Jinggong Technology to promote the localization of high-performance carbon fiber, and also accumulating valuable experience for the company's continuous technological iteration and large-scale industrialization in the future.

In terms of product applications, high-performance carbon fiber can be widely used in aerospace, energy equipment, automotive industry, high-end sports equipment, medical devices and other fields, providing key material support for national strategic directions such as aerospace (low altitude) economic development and transportation lightweighting. Meanwhile, as an important component of the green and low-carbon industry, the large-scale production of high-performance carbon fiber raw fibers will effectively promote energy conservation and emission reduction in downstream industries, contributing to China's achievement of the "dual carbon" goal.

Looking ahead to the future, Jinggong Technology will take the smooth operation of this carbon fiber raw silk production line as the starting point, continue to deepen the layout of the entire carbon fiber industry chain, deepen the integration of technological innovation and industrial innovation, steadily enhance the core competitiveness of the industry, and contribute greater strength to building a globally leading high-end equipment for the entire carbon fiber industry chain.
