Product Description

Vertical Enamelled Wire Production Line for Φ0.05-3.0mm Wires

Product Description
This fully automated vertical enamelled line produces high-quality insulated winding wires for electric motors, transformers, and precision instruments. The complete process includes:
Pay-off → Annealing → Coating → Curing → Cooling → Lubrication → Take-up.
The system supports round, flat, and self-bonding wires with superior film uniformity (±0.5µm) and zero pinholes (≤3 defects per 10,000 meters).

Annealing Furnace: Continuous hydrogen-protected annealing at ≤500°C
Coating Unit: Felt applicator with precision metering pumps
Curing Oven: 5-tier vertical catalytic curing with heat recovery
Cooling Section: Forced air cooling with purified air supply
Lubrication System: Controlled oil application
Take-up System: Dual-station spooling with tension control
Exhaust Treatment: RTO catalytic combustion (VOC ≤20 mg/m³)
Control System: EUROTHERM automation with HMI touchscreen
Diametric Measurement: Laser gauges for real-time monitoring (optional)

Detailed Process Description
1. Pay-off
Tension control is critical to avoid wire elongation or surface damage
Brush-type pay-off for fine wires (Φ<0.1 mm), rotary for larger diameters
Tension maintained at ≤20% of non-elongation limit (2-15 kg/mm² based on temperature)
2. Annealing
In-line continuous annealing at ≤500°C under hydrogen atmosphere
Water seal provides steam protection against oxidation

3. Coating
Felt applicator system utilizing capillary action
Felt density and thickness tailored to wire diameter
"Thin coats, multiple passes" ensure uniformity and avoid dripping
Viscosity and surface tension tightly controlled per wire size
4. Curing
Zones: Evaporation (solvent removal) → Curing (polymer cross-linking)
Transverse temperature variation ≤5°C; longitudinal profile adjustable
Solvent evaporation must occur without boiling to avoid pinholes
Polyimide requires partial curing per pass to prevent delamination
5. Cooling & Lubrication
Forced air cooling (water cooling avoided to prevent moisture inclusion)
Lubrication applied at 1 g/m² for smooth spooling without visible oil
6. Take-up
Tension controlled at 10-25% of non-elongation limit based on wire size
Line speed ratio between take-up and traversing: 1:1.7-2.0
Quality Assurance
Film Uniformity: ±0.5 µm (laser gauging optional)
Pinhole Test: ≤5 defects/30 m (IEC 60851)
Adhesion & Flexibility: No cracking or peeling after elongation
Thermal Endurance: Class 180 (H-grade)
Certifications: UL, CE, ISO 9001
Warranty: 12 months on oven and control system
