Why Dingtian Leads in Ultra-Fine Wire Drawing for Electronics

Changzhou Dingtian Electrical Machinery Co., Ltd. addresses one of the wire and cable industry’s most persistent pain points: mechanical tension fluctuation that causes wire breakage, diameter variation, and excessive reliance on operator skill — all compounded by prohibitively high international equipment prices. Dingtian’s strategic response is a full-spectrum lineup of precision wire drawing machines, ranging from ultra-micro full-servo systems to tension-rod-free and in-line continuous annealing configurations, purpose-built for electronic wire and wire cable manufacturers.

Core Technology and Product Highlights

Full-Servo Ultra-Fine Drawing Platform
Dingtian’s QSF45-10 Full Servo Ultra-Micro Fine Wire Drawing Machine is its most technically advanced offering for electronic component applications. It supports a finished wire diameter as fine as 0.0085 mm — approximately one-seventh the diameter of a human hair — with a diameter tolerance held within ±0.0005 mm. The machine uses customized Inovance servo components to realize fully linear automatic control of take-up slip, eliminating the mechanical tension rod fluctuations that plague conventional machines. Its full digital computer control system automatically locks parameters after setting and stores recipes for quick recall when switching wire specifications or dies, significantly reducing setup time and operator error risk. Equipment pricing is positioned at approximately one-tenth of international brand equivalents for selected ultra-micro models.

Slip-Type Micro-Fine Drawing Platform
For cost-sensitive operations requiring high throughput, Dingtian’s SPS85-15 Slip-Type Micro-Fine Wire Drawing Machine delivers wire diameter accuracy stably controlled within ±0.001 mm using a dual-inverter solution. The tension-rod-free design reduces wire breakage by more than 90% compared with conventional machines. Material compatibility extends across copper wire, oxygen-free copper wire, alloy wire, copper-clad aluminum alloy wire, silver-copper wire, tin-copper wire, silver-plated wire, precious metal fine wire, bonding gold wire, and silver wire — reducing the need for material-specific equipment investment.

High-Speed Tension-Rod-Free Drawing
The LHS240-24 Tension-Rod-Free Fine Wire Drawing Machine reaches a maximum line speed of 2,500 m/min. For 0.2 mm finished copper wire, this translates to approximately 2,880 km of daily output at 2,000 m/min and approximately 3,600 km at 2,500 m/min — a 25% capacity increase under the same process and wire specification. Enhanced dual-inverter closed-loop slip control suppresses tension impact during startup, shutdown, and speed adjustment, avoiding uneven wire thickness.

In-Line Continuous Annealing Integration
The LHST150-24 Fine Wire Drawing Machine with In-Line Continuous Annealing integrates wire drawing, annealing, cooling, and take-up in a single footprint, eliminating secondary annealing process steps for ultra-fine soft copper wires of 0.05 mm to 0.10 mm. An enclosed annealing channel with saturated steam isolation produces a bright wire surface free of oxidation and blackening, eliminating subsequent pickling. Whole-machine linkage optimization delivers 12% to 20% lower overall power consumption compared with separated equipment configurations.

Automatic Spool Change for Unmanned Production
The LHSZ240-24 Servo Tension-Rod Fine Wire Drawing Machine with Automatic Spool Change enables non-stop dual-spool automatic changeover without wire breakage. Where conventional machines require spool changes every 2 to 4 hours, this model supports continuous operation for more than 8 hours, increasing the number of machines manageable per operator by over 50%.
