A Unified Language for Carbon Fiber Equipment: National Standard for Precursor Machinery Set to Close the Loop on Full-Process Standardization

Competition in the carbon fiber industry is shifting from 'can we make it' to 'can we make it consistently and cost-effectively.' The key to this shift often lies not in the final high-temperature carbonization furnace, but in the upstream precursor machinery. In July 2026, a landmark national standard was approved: 'Terminology, Classification and Model Numbering Method for Polyacrylonitrile Fiber Production Complete Equipment' will take effect on February 1, 2027. This is China's first unified technical language system for carbon fiber precursor machinery, marking a transition from isolated breakthroughs to a fully integrated standardization framework.

Why the Standard Gap Was a Bottleneck Polyacrylonitrile (PAN) precursor is the precursor to carbon fiber, directly determining the strength and stability of the final product. The production process involves multiple stages—polymerization, spinning, drawing, drying, and solvent recovery—each with complex equipment. For years, the absence of unified terminology and classification meant that different manufacturers used different names for the same machine. During production line design, technical alignment required significant time for 'translation' and verification. Equipment procurement was hampered by chaotic model numbers, making it difficult for buyers to compare products from different suppliers. This lack of standardization silently eroded supply chain efficiency. The new standard, led by Jinggong Technology and Huachuang Technology, for the first time unifies terminology, classification, and model numbering across the entire precursor production process. For the industry, this is equivalent to giving every piece of precursor equipment a 'national ID card' and a universal manual.

From Carbonization to Precursor: How a Closed-Loop Standard Reshapes Competition This is not Jinggong Technology's first national standard in carbon fiber equipment. Previously, the company led the development of 'Terminology, Classification and Model Numbering Method for Fiber Carbonization Production Complete Equipment,' which took effect in June 2025. The carbonization standard addressed 'how well it burns,' while the precursor standard addresses 'how stably it spins.' Together, they create the first unified standard system for China's carbon fiber equipment, covering the entire process from precursor to carbonization. For equipment suppliers, a unified standard provides a clear technical reference for product design and iteration. For downstream carbon fiber producers, equipment selection and production line integration become more transparent and efficient, potentially improving compatibility between different brands and reducing construction and upgrade costs. From a broader perspective, this standardization closure is crucial for domestic carbon fiber to compete globally. International carbon fiber giants have long held technological discourse power in equipment and processes. The establishment of a standard system means domestic equipment has taken a step from 'can do' to 'can define and standardize.'

From Standards to Industry: The Next Steps for Large-Tow and High-Performance Fibers Jinggong Technology has stated that it will continue to collaborate with Huachuang Technology, leveraging the two national standards to promote group standards and tackle core bottlenecks in large-tow and high-performance PAN precursor and carbonization equipment. Large-tow carbon fiber is the primary material for industrial applications like wind turbine blades and pressure vessels, where cost sensitivity is extreme. High-performance PAN precursor is the foundation for aerospace-grade carbon fiber, demanding exceptional quality and stability. These two directions represent the most urgent areas for domestic substitution and where the technology gap remains widest. Standardization can lower the barrier to technology diffusion, but it cannot directly solve the 'hardcore' problems of material formulation and process control. Equipment precision, intelligence, and solvent recovery efficiency still require sustained R&D investment within the standard framework.

Practical Recommendations

For Buyers - Prioritize equipment that complies with the new national standard's terminology and classification system to reduce compatibility risks during future production line upgrades and spare parts procurement. - In technical agreements, require suppliers to provide the standard classification code corresponding to the equipment model, facilitating cross-manufacturer price comparison and technical benchmarking.

For Equipment Manufacturers - Conduct a thorough review of existing product line models and adjust them to comply with the national standard before it takes effect, avoiding disqualification from tenders due to non-compliant model numbers. - Use the standardization window to clarify your technical advantages in specific segments such as polymerization, spinning, or solvent recovery, building differentiated competitiveness.
