In August 2026, a milestone was reached in the localization of carbon fiber precursor production equipment. Jinggong Technology, together with Zhejiang Huachuang Carbon Fiber Technology Co., Ltd., Donghua University, and Zhejiang University of Technology, completed the scientific and technological achievement certification of a '5000-ton DMSO dry-jet wet-spinning high-performance PAN-based precursor complete equipment and process' in Shaoxing. The certification concluded that the overall technology has reached internationally advanced levels, with two indicators—DMSO recovery steam consumption and temperature uniformity in the polymerization reactor—leading globally. This marks a substantial breakthrough in addressing the long-standing reliance on imported equipment for high-end carbon fiber precursor production.
Industrial Coordinates of the Technical Breakthrough
Precursor is the core of carbon fiber performance, and its production equipment and process have long constrained China's self-supply and industrial security in the high-end carbon fiber sector. In the past, domestic carbon fiber enterprises often relied on imported equipment for high-performance precursor lines, facing high procurement costs and restricted technological iteration. The certified equipment set delivers hard-nosed answers on several key parameters: temperature uniformity of ±0.4°C in the reactor under effective filling, terminal pressure deviation of ±1% for high-viscosity PAN dope, spinneret pressure fluctuation of 1‰, process speed of 280 m/min, and single-line capacity of 5,000 tons/year. Behind these numbers is a systematic solution to engineering scale-up challenges—heat transfer lag and insufficient local mixing in high-viscosity polymerization systems, which were once insurmountable barriers for domestic equipment.
From an industrial belt perspective, Shaoxing, as a major domestic base for chemical fiber and textile equipment manufacturing, has further consolidated its regional competitiveness in high-end equipment through this achievement. For procurement managers, this means that when selecting equipment for domestic carbon fiber precursor lines, there is now a local option with international benchmarking capability.
Cost-Reduction Logic Behind Key Indicators
In the cost structure of carbon fiber production, energy consumption and solvent recovery efficiency in the precursor stage directly affect the market competitiveness of the final product. The project achieves a DMSO recovery rate of no less than 99.5%, steam consumption for recovery no higher than 2.2 t/t, recovered purity of 99.88%, and residual solvent in wastewater below 100 ppm. These indicators not only ease environmental compliance pressure but also directly relate to cost reduction per ton of precursor. For downstream carbon fiber manufacturers, lower solvent costs and stable recovery system operation will significantly improve the economics of the precursor segment.
Another noteworthy point is the introduction of an intelligent production management system. The MOM system and central control visualization platform enable visualization, quality traceability, equipment management, and energy consumption control in large-scale precursor production. This is not merely automation but a shift from 'experience-driven' to 'data-driven' manufacturing, which has long-term value for batch consistency and yield improvement. As carbon fiber applications expand, stable precursor quality is a prerequisite for downstream composite material manufacturers to build confidence.
Transmission Effects on the Upstream and Downstream Chain
The breakthrough in precursor equipment primarily affects precursor manufacturers—they can access cost-effective domestic equipment, lowering expansion barriers. Second, equipment localization will force imported equipment prices to return to reasonable ranges, increasing bargaining power even for those who still choose imports. For upstream suppliers of polymerization reactors, spinning components, and solvent recovery systems, this signals the formation of a new supporting market.
From a broader perspective, this certification coincides with the overall capacity expansion cycle of China's carbon fiber industry. According to public industry data, domestic carbon fiber capacity continues to grow, but there is still a gap in high-end precursor supply. This equipment set helps alleviate this structural contradiction, promoting the application of carbon fiber in high-end fields such as aerospace, wind turbine blades, and pressure vessels. For foreign trade enterprises, if the equipment is export-competitive, it could open a new track for 'technology export,' but attention must be paid to international patent layout and customer certification cycles.
