On January 28, 2026, Ningbo Yijun Technology Co., Ltd. (hereinafter referred to as "Yijun Technology")'s independently developed 3T thread rolling machine was mass-producing
Precision Screws of M2 to M12 specifications at a production efficiency of 600 pieces per minute. This equipment, integrating intelligence, high precision, and high adaptability, has successfully entered the high-end markets of Europe and North America with its breakthrough technical indicators and full-process digital control capabilities, becoming a new benchmark for "Made in China" fasteners globally.
The core advantage of Yijun Technology's 3T thread rolling machine lies in its micron-level processing precision and multi-material adaptability. Equipped with a self-developed PLC control system and infrared spectral analysis module, the equipment can adjust rolling parameters in real time, improving the roundness detection accuracy of nut inner holes from the industry average of 0.1 mm to 0.03 mm, and even achieving tolerance control of ±0.002 mm in the processing of M1.6 ultra-small screws. This data has reached the same level as leading German and Japanese brands, completely breaking the long-standing monopoly of foreign capital in the high-end market.
"Traditional thread rolling machines are prone to cracking or dimensional deviations when processing high-hardness materials such as stainless steel and titanium alloys. Our equipment, through dynamic pressure compensation algorithms and TD coating mold technology, reduces the defect rate from 3% to 0.05%," said the technical director of Yijun Technology. According to actual test data, when processing M12 high-strength bolts, the thread depth deviation is only 0.02 mm, a 5-fold improvement in accuracy compared to traditional processes.
Since mass production began in early 2026, the 3T thread rolling machine has secured bulk orders from Italy, Germany, France, and other countries. Among them, the M1.6 screw production line customized for a high-end precision instrument manufacturer in Italy has become a "no-inspection link" in the customer's supply chain thanks to its end-to-end digital traceability system and real-time infrared detection reports.
"The infrared spectrum and dimensional data of each screw are recorded in detail, which provides us with crucial information for optimizing the assembly process," commented an Italian customer representative during a factory visit. "This level of transparency is extremely rare in European and American supply chains. Yijun Technology has redefined the credibility of 'Made in China'."
According to statistics, in January 2026, Yijun Technology's fastener orders exported to Europe increased by 200% year-on-year, with screws for new energy vehicle battery pack assembly accounting for over 60%. A German Tier 1 supplier has even listed Yijun Technology as a "core strategic partner," stating that its equipment "achieves equivalent quality at one-third the cost."
As a rising star company founded in October 2025, Yijun Technology's rise stems from its relentless pursuit of technological innovation. The company invests 15% of its annual revenue in R&D and currently holds three patents related to infrared detection. It plans to launch a defect prediction model that fuses AI visual recognition with infrared spectroscopy in the second half of 2026, further improving detection efficiency by 30%.
"Our goal is not to become the largest screw manufacturer, but to become an irreplaceable technological solution provider in the field of micro-precision manufacturing," revealed founder Hou Hui. The company is currently collaborating with local universities in Ningbo to develop a thread rolling process for superhard materials, and plans to expand into high-end fields such as aerospace and medical equipment in the future.
Yijun Technology's case reflects the profound transformation of Ningbo's manufacturing industry. As an important fastener production base in China, Ningbo has over 2,000 related enterprises, but the high-end market has long been monopolized by German and Japanese companies. Emerging companies like Yijun Technology are reshaping the global supply chain landscape through intelligent equipment, digital management, and global services.
