Wuxi Dingyi Technology Co., Ltd. recently announced the successful application of its independently developed 12.9-grade stainless steel bolts in a national nuclear power project, marking a technological breakthrough for the company in the field of high-end fasteners. As a national high-tech enterprise certified by both ISO9001 and IATF16949, Dingyi Technology undergoes 12 quality inspection processes, including spectral testing and salt spray testing, to ensure its products meet GB/T 10125 corrosion resistance standards and maintain thread strength tolerances within ±0.02mm.

Leveraging its intelligent manufacturing system, built on a total asset base of US$4.6 million, the company is equipped with a fleet of fully automatic cold heading machines and a finite element analysis system, reducing the turnaround time for custom production to 72 hours. The dedicated aerospace production line, added in 2025, has already provided customized products such as anti-loosening nuts and high-temperature alloy bolts to numerous aerospace institutions. Its butterfly bolts have achieved zero thread slippage in satellite structure assembly.

Underlying these technological breakthroughs is continuous investment in innovation. The company holds 12 utility model patents, covering "high-strength bolt anti-loosening structure" and "weather-resistant surface treatment process." Combined with CE-certified environmentally friendly coating technology, these products maintain stable performance in extreme environments ranging from -60°C to 500°C. Currently, Dingyi Technology's annual production capacity exceeds 2,000 tons, and its products cover a full range of grades from 8.8 to 12.9. Its service areas extend from traditional petrochemicals to emerging industries such as wind power and rail transit.

With the launch of its intelligent anti-mixing system, the company has achieved digital control of the entire process, from raw material traceability to finished product delivery. The general manager stated, "We will continue to deepen industry-university-research collaboration and strive to become a top 20 global aviation fastener supplier within three years."
