SUMEC TOUCH WORLD

     Our company produces large-size spiral bevel gears that are widely used in various products such as bevel gear shafts for rotary tillers, gearbox gears for tractors, front axle gears for tractors, rear axle gears for tractors, and engineering machinery gears. The primary customer base includes agricultural machinery enterprises, construction machinery enterprises, and higher education institutions. Our products are sold domestically to nearly 20 provinces, including Shandong, Hebei, Henan, Jiangsu, and Zhejiang, as well as internationally to countries such as Japan and Italy.  

     The large-size spiral bevel gears manufactured by our company are core basic components in China's national industrial "Five Fundamentals" initiative, filling the technological gap in near-net-shape forming of precision large-size spiral bevel gears. They have been successfully integrated into major enterprises such as First Tractor Co., Ltd., Kubota (Suzhou) Agricultural Machinery Co., Ltd., and Jiangling Motors Group, reducing China's reliance on imported high-end large-size spiral bevel gears.  

     We have launched a series of high-quality products represented by "large-size spiral bevel gears," mastering international leadership in key technologies such as metal plastic flow and tooth profile filling during the forming process, warm-cold and hot-cold forging precision forming, and precision refinement after hot or warm forging of spiral bevel gears. We have established precision forming design and accuracy control methods, equipped all production lines with high-precision advanced equipment, and enhanced intelligent manufacturing capabilities, achieving gear machining accuracy of 0.001mm—setting a new benchmark in the gear manufacturing industry.  

     By replacing pre-heat-treatment gear milling with a hot forging-cold extrusion composite forming process, gear manufacturing efficiency has increased by 48%, material utilization has improved by 15%, and fatigue life has extended by 50%. This innovation has opened up a new green, fatigue-resistant manufacturing technology field for large-size spiral bevel gears, preliminarily realizing import substitution of core components for high-horsepower tractor transmission systems.  

     The precision forming technology for large-size spiral bevel gears is primarily applied in the transmission systems of heavy-duty vehicles, medium and large tractors, and engineering machinery, owing to its suitability for heavy loads and cost-effective mass production.

With perseverance and determination, they forge ahead against the current. In 2024, facing the highly competitive domestic industry environment and complex international situation, many enterprises struggled under the dual pressures of high operating costs and weak market demand. However, the teams of Yancheng Jingangxing and Xiaoye Agricultural Machinery, with their indomitable spirit and diligent efforts, overcame numerous difficulties and achieved a 26% year-on-year growth in invoiced sales, demonstrating remarkable resilience and vitality.

Green transformation and technological strength. Yancheng Jingangxing adheres to its core business of gears and relies on its parent company. The enterprise continuously promotes the strategy of strengthening itself through technology. In September and October 2023, it was successively awarded the titles of National Green Factory and "Specialized, Refined, Unique, and Innovative" enterprise, achieving a win-win situation of economic benefits and environmental protection. In 2024, Yancheng Jingangxing and Xiaoye Agricultural Machinery forged ahead in adversity. Through independent research and technological innovation, they successfully launched several agricultural machinery products with independent intellectual property rights, earning wide recognition in the market.

Independent research and development, filling the gap. In April 2022, during a trip to Xinjiang, Yancheng Jingangxing decided to undergo a strategic transformation from parts to complete machines. In July of the same year, the Xiaoye Agricultural Machinery team was established under the leadership of Tian Naiqiang and Lyu Xiao, embarking on a journey of rebirth for the enterprise. After 548 days of relentless efforts, the Xiaoye Agricultural Machinery team successfully developed the XYS2604 tractor, filling the gap of no local production in Sheyang County since its establishment. This tractor not only features high precision and performance but also incorporates a large number of independently developed core technologies, becoming one of the most complete large-horsepower tractors in terms of self-made parts in the country.

Rich product lines, meeting diverse needs. While developing tractors, Yancheng Jingangxing and Xiaoye Agricultural Machinery also actively expanded their product line of large agricultural machinery. In 2022, the enterprise successfully developed and mass-produced a series of drive harrows ranging from 2.5 meters to 7 meters.
