Product Summary

The 24-2DT is a fine wire drawing machine built for double bare copper wire production. Two inlet wires of Ø0.6–1.2 mm are drawn down to two outlets of Ø0.1–0.3 mm at a maximum drawing speed of 2000 m/min. Each line runs 24 dies in a four-spool, double-tier arrangement using horizontally sliding continuous drawing. Continuous DC four-section annealing is integrated into the line, so drawn wire leaves the machine annealed rather than needing a separate annealing pass. Compared with a traditional single-wire drawing and annealing machine, this dual-wire design saves floor space, power consumption and labour for the same output.

Key Features

• Two wires drawn and annealed simultaneously — 2 x Ø0.6–1.2 mm inlet to 2 x Ø0.1–0.3 mm outlet, up to 2000 m/min, so one machine and one operator cover double-wire output.
• DC four-section annealing at DC 70 V, 600 A max, 42 KVA — a water impingement cooling system holds a stable water level in the annealing chamber, supporting constant elongation and conductivity without the operator adjusting water flow at any wire size or speed.
• Extended pre-heating and annealing length — longer annealing sections allow higher running speed and higher productivity per shift.
• Ceramic-coated capstans and pulleys — four 11-tier capstans plus one single-tier capstan for final drawing, with ceramic-coated aluminium pulleys to reduce surface marking on fine copper wire.
• Shaftless double-bobbin pneumatic take-up, 25 kg x 2 spool capacity — pneumatic bobbin clamping handles small-bore bobbins that cannot run at high speed on traditional shaft-type take-up units, and speeds up bobbin loading and unloading.
• Swing-arm weight balance with automatic spooling tension correction — combined with step-motor traversing whose speed is adjustable to the drawing speed, keeping package build consistent across the run.
• Brake motor control — the machine brakes automatically when the power supply is cut, so no UPS is required.

Technical Specifications

Models and Options

Model 24-2DT is the configuration documented on this page: double wire, 24 dies per line, integrated DC four-section annealing and shaftless double-bobbin pneumatic take-up. Spool dimensions are made to customer order, and dies are supplied by the customer to the Ф25 mm x 8–10 mmT specification, so wire size and package size are matched to your line rather than fixed. The model is named in CE verification of conformity CE-JL26020401-AL-MD issued by ICG for the EU market, valid from 2026-02-10 to 2031-02-09, alongside other models of the same range. Please contact the manufacturer for configurations outside the scope of this page.

Materials and Structure

The frame is welded from steel plate for heavy-duty running stability. Die No.1 is mounted independently while dies No.2–23 are cast iron, and the die pedestal can be adjusted according to the capstan position. Drawing transmission uses timing belts, with flat belts on the remaining drives. Capstans are ceramic coated and the pulleys are ceramic-coated aluminium, which limits wear and marking on fine copper. Lubrication is spray type at 40 L/min with independent lubrication pipes for die No.1 and die No.24; the lubrication system is supplied without a water pump and tank. Electrical control components are drawn from top-class brands in China, Taiwan or overseas.

Applications

The 24-2DT is used for efficient production of fine-diameter metal wire in wire and cable manufacturing, electronics, hardware, and alloy wire processing. Its primary duty is bare copper fine wire drawing with in-line annealing, where two wires run in parallel to feed downstream bunching, stranding or enamelling operations.

Customization

Spool dimension is customized to your take-up package requirement, and dies are provided by the customer in the Ф25 mm x 8–10 mmT size, allowing the die series to be matched to the final wire specification. Spooling tension is corrected automatically through the swing-arm weight balance, and traversing speed is adjustable to suit the drawing speed in use. The machine is built around a three-phase 415 V 50 Hz supply with AC frequency converter control on the 22 KW driving motor and both 2.2 KW spooling motors. Discuss your wire range and package size with the manufacturer before ordering.
