New 2500 m/min Fine Copper Wire Drawing Machine with Dual Inverter Control and Ceramic Capstan

The global push toward electrification, tighter motors and lighter cables has pushed copper wire specs into new territory: drawn wire down to 0.08 mm, produced at speeds that used to be impossible on a single machine. To answer that demand, Wuxi Tripod Machinery has released an upgraded fine copper wire drawing machine built around dual inverter power control and ceramic sprayed capstans, capable of running 24 dies at a maximum line speed of 2500 m/min.

This machine was designed for wire and cable manufacturers who need consistent fine-gauge copper wire — from 1.0 mm inlet down to 0.08–0.25 mm outlet — without sacrificing surface quality, die life or uptime.

The unit combines a rigid cast iron frame with an 11 KW main motor and a 3.7 KW take-up motor. Power is delivered through a dual inverter control system, which keeps the main drawing section and the take-up section independently regulated. The result is stable tension from the first die to the spool, even when the operator changes line speed mid-run.

Drawing capstans are ceramic sprayed, a treatment that dramatically reduces friction and wear compared with plain steel wheels. This matters most in fine wire production, where surface scratches and micro-scoring translate directly into rejected spools and customer complaints.

• Dual inverter control — independent regulation of main drive and take-up for stable, repeatable tension and smooth acceleration.
• Ceramic sprayed drawing capstans — lower friction, longer lifespan, and a cleaner wire surface at fine gauges.
• Up to 24 dies in a single pass, with a mechanical reduction rate of 13% and a fixed speed wheel surface reduction rate of 8%.
• 2500 m/min maximum line speed for high-output production without extra floor space.
• Weight balance type tension control — a proven, mechanically simple design that keeps dancers stable at high speed.
• Jacking screw pressing type take-up with synchronous motor and belt traversing for evenly wound, D300 bobbins.
• Spray lubrication and electromagnetic braking — consistent cooling of dies and capstans, plus fast, controlled stops.
• Flat belt transmission — quiet operation, low vibration, and easy maintenance.

The machine fits cable and enamelled wire plants producing fine copper conductor, automotive harness wire, electronics lead wire, and enamelled magnet wire. Compared with older single-inverter frames, the dual inverter architecture lets operators fine-tune slip between drawing and take-up, which reduces wire breakage on the finest dies — typically the biggest source of downtime in fine wire drawing.

The compact 2000 × 1600 × 1900 mm footprint allows the machine to be slotted into existing lines without major civil work, and flat belt transmission keeps noise levels low enough for normal workshop environments.
