On January 9th, the Zhejiang Provincial Department of Economy and Information Technology announced 327 certifications for the first equipment in Zhejiang Province for 2024. Jinggong Technology's "JCYY300D Gas Electric Hybrid Heating End to End Pre Oxidation Furnace" ranked first in the "Domestic First Equipment" certification. Thus, Jinggong Technology has also become the first enterprise in Keqiao District to hold two titles of "China's first (set) equipment".

The "first (set)" is the abbreviation for "first (set) major technical equipment", which refers to equipment products that have undergone significant breakthroughs in variety, specifications, architecture, or technical parameters through innovation, have intellectual property rights, and are independently developed for the first time. The overall performance or core technical indicators of the equipment have reached the leading domestic or international advanced level of similar equipment.

Jinggong Technology ranks first in this year's "Domestic First Equipment" certification

Jinggong Technology has been laying out its carbon fiber business since 2013, with provincial-level enterprise research institutes and national level carbon fiber equipment product research and development centers. After eleven years of technological accumulation, it has developed into the first domestic provider of high-end carbon fiber equipment and advanced composite new material integrated solutions.

Pre oxidation furnace is one of the important key devices in carbon fiber production line. The JCYY300D gas electric hybrid heating end-to-end pre oxidation furnace independently developed by Jinggong Technology effectively solves the "bottleneck" problem in carbon fiber equipment manufacturing, making equipment operation more stable, efficient, and energy-saving. Verified by authoritative experts in the industry, the technology has reached the international advanced level.

This equipment adopts key technologies such as pneumatic electric hybrid, online cleaning, large channel wide aperture labyrinth multi-layer air curtain blowing and sealing, while achieving innovation and breakthroughs in multiple technologies——

We have developed end-to-end distributors, online pull-out cleaning devices, and gas sealing devices to achieve stable pre oxidation of large fiber bundles while reducing environmental pollution and energy consumption;

Two control systems for gas electric hybrid heating devices have been developed, and precise adjustment and coordinated operation of the two heating methods have been achieved through PID. The maximum mechanical speed can reach 20m/min, achieving stable operation and efficient energy utilization of the pre oxidation furnace. Compared with traditional pre oxidation furnaces, it can save about 30% energy;

A high-precision technical thermal flow coupling analysis model has been constructed to optimize the internal structure of the pre oxidation furnace, improve the uniformity and stability of the thermal flow field, and lay the foundation for the preparation of higher performance carbon fibers;

A multi parameter intelligent control system integrating perception, communication, processing, control, and execution has been built to achieve real-time monitoring, automatic control, and optimized management of the pre oxidation furnace, significantly improving the stability and product quality in the production process.

The achievement of the honor of "the first domestic equipment" marks a new breakthrough and innovation in technology research and development, product innovation, and process methods for Jinggong Technology. For the first time, it has achieved professional production of pre oxidation wire equipment manufacturing, formed core independent intellectual property rights, broken international technical barriers, and filled the technical gap in the field of pre oxidation wire equipment in China.

At the beginning of 2025, Jinggong Technology once again won the heavyweight honor of "China's first (set)", which is a recognition of the achievements of the past year and an incentive for future development. In the future, Jinggong Technology will continue to focus on technology research and investment in key areas, deeply cultivate technological innovation and process optimization of the entire carbon fiber industry chain equipment, and strive to develop towards the three in one of "equipment+materials+applications", contributing more Jinggong wisdom to the development of the global carbon fiber industry.
