With the rapid development of high-end manufacturing industries such as new energy vehicles, 5G communications, and medical devices, the demand for precision wire continues to surge, driving a wave of technological innovation in the fine wire drawing machine sector.
In the field of ultra-precision processing, Changzhou Dingtian Electrical Machinery Co., Ltd. has achieved a major technological breakthrough. Its independently developed QSF45-10 full-servo fine wire drawing machine has successfully produced silver-copper alloy wire with a diameter of only 0.0085 mm—approximately one-seventh the thickness of a human hair—filling a domestic technological gap in military applications, unmanned aerial vehicles (UAVs), and minimally invasive medical fields. This achievement underscores Dingtian’s leadership in precision wire solutions and aligns with global manufacturing demands.

The QSF45-10 uses a customized Inovance servo system and a 24-pass precision drawing process to strictly control wire diameter tolerance within ±0.0005 mm—far exceeding the industry average of ±0.001 mm. It has become core equipment for high-end sectors such as military electronics, UAV communications, and minimally invasive medical instruments. Previously, such ultra-fine wire processing equipment was dominated by foreign manufacturers like Japan’s Tokyo Rope and Germany’s Schunk, with unit prices exceeding RMB 30 million. In contrast, Changzhou Dingtian’s comparable products are priced at only 60 % of imported equipment costs, with delivery cycles shortened by 50 %, significantly improving accessibility and competitiveness.
Technological innovation is the core competitiveness of Changzhou Dingtian. The company has established an integrated R&D system covering “material research – process optimization – equipment manufacturing” and has taken the lead in formulating the industry standard Technical Requirements for Ultra-Fine Wire Drawing Equipment.
To address processing challenges with different wire materials, Changzhou Dingtian provides customized solutions. For high-temperature alloy wires prone to brittleness and fracture, the company developed a “gradient tension control + segmented annealing” technology, reducing wire breakage rates from the industry average of 5 % to 1.2 %. For precious metal wires with high material loss, optimized die design and lubrication systems increased material utilization from 82 % to 95 %, enabling customers to save over one million RMB annually in raw material costs per machine.
The QSF60-12 intelligent fine wire drawing machine integrates laser online detection, AI-based tension prediction, and a digital twin system, enabling fully automated processing of wires ranging from 0.0085 mm to 0.1 mm. Effective production time has increased to 92 %, improving overall efficiency by 35 % compared with traditional models.
In terms of energy efficiency, Changzhou Dingtian has developed a fine wire drawing and annealing machine capable of producing 0.04–0.10 mm soft-finished wire. Compared with similar imported equipment, energy consumption is reduced by 14 %, making it the preferred choice for alloy wire manufacturers.
With continuous breakthroughs in core technologies for domestically produced equipment, Changzhou Dingtian is further consolidating its leading position in the global ultra-fine wire processing equipment market, driving China’s precision equipment manufacturing industry toward the mid-to-high end of the global value chain.
