Our Wet Wire Drawing Machine (Water Tank Wire Drawing Machine) is specially designed for high-speed continuous drawing of low/high carbon steel wire, stainless steel wire, galvanized wire, and non-ferrous metals. Designed to process fine wires ranging from 0.5mm to 2.0mm, this machine integrates advanced cooling technology, tension synchronization, and wear-resistant capstans to deliver smooth wire finishes without wire breakage.
What is Wet Wire Drawing?
A wet wire drawing machine is a wire drawing machine that completes the process by immersing the wire in a liquid lubricant. This lubrication method reduces friction, improves surface quality, and enables high-speed production.
Compared with dry drawing, the wet wire drawing process is widely used for fine wire manufacturing where precision and surface finish are critical.
Wet Wire Drawing Process
The typical wet wire drawing process includes the following steps:
Wire Rod → Cleaning → Lubrication (Liquid) → Multi-pass Drawing → Cooling → Coiling
During the process, the wire passes through multiple dies inside a liquid-filled system, ensuring continuous lubrication and cooling.

Advantages of Wet Wire Drawing Machine
1. Full Immersion Cooling & Lubrication System
To prevent wire thermal expansion, brittleness, and heat-induced breakage during high-speed drawing, our machine features a fully submerged or high-pressure spray water tank cooling system.
- Total Heat Dissipation: Both the drawing dies and capstans are fully immersed in drawing lubricant fluid, effectively dissipating heat at high linear speeds.
- Extended Die Lifespan: Continuous lubrication reduces friction coefficient between the wire and tungsten carbide dies, eliminating surface scratches and die wear.
- Clean Operating Environment: Fully enclosed tank design prevents coolant splashing and keeps your workshop clean and compliant with industrial safety standards.
2. Carbide/Ceramic Spray-Coated Capstans & Precision Die Setup
The drawing capstans are the heart of fine wire quality. We utilize heavy-duty capstans built for long-term wear resistance under high tension.
- Tungsten Carbide & Ceramic Coating: Capstan surfaces undergo plasma-sprayed tungsten carbide or high-hardness ceramic treatment (HRC 62+), delivering exceptional wear resistance and smooth wire guidance.
- Multi-Pass Die Alignment: Designed for 9 to 13 drawing passes with flexible die sizing, allowing smooth step-down ratios tailored to your raw material tensile strength.
- Individual/Block Cooling: Internal water circulation keeps capstan surface temperatures uniform during continuous 24/7 production runs.
3. Siemens PLC & PID Tension Synchronization Control
Maintaining uniform wire diameter and preventing wire stretching (thinning) or snap breaks requires absolute tension control.
- Dual Inverter Drive with PID Feedback: Equipped with dual frequency inverters (VFD) and a dancing roller tension feedback system to maintain constant wire tension across all speed acceleration/deceleration phases.
- PLC Touchscreen Interface: Siemens PLC allows real-time monitoring of drawing speed, meter counting, auto-stop on wire break, and fault diagnostics.
- Smooth Take-Up Integration: Seamlessly synchronizes with automatic spooler take-up or coiler units, ensuring tight, neatly wound wire coils ready for downstream mesh welding or galvanizing lines.

FAQ of Wet Wire Drawing Machine
What materials can a wet wire drawing machine process?
The RKM wet wire drawing machine can process stainless steel wire, copper wire, aluminum wire, and various alloy wires. It is especially suitable for producing wires requiring a high surface finish.
What is the main difference between wet and dry wire drawing?
The main difference lies in the lubrication method. Wet wire drawing uses liquid lubrication, which provides better cooling and ensures the surface quality of the wire. Dry wire drawing relies on powder lubrication and is more suitable for larger diameter wires.
Is a wet wire drawing machine suitable for processing fine stainless steel wires?
Yes. Wet wire drawing machines are widely used for processing fine stainless steel wires because liquid lubrication helps reduce friction, results in lower drawing temperatures, and virtually eliminates wire breakage, thus achieving a smooth and uniform wire surface.
How to reduce wire breakage during wet wire drawing?
A proper lubrication system, precise drawing dies, stable drawing speed, and correct tension control can reduce wire breakage.
