Coating Compatibility with Enameling Dies
Different insulation materials require specific die properties for optimal coating results. Contact us now for a free solution to your application needs.
Enameling drawing die with Polyester requires smooth die surfaces (Ra <0.1μm) to prevent viscosity-driven streaks. Consistent coating at high speeds (up to 50m/s), reducing pinhole defects
Choose PEI as your enameling die coating needs thermal–stable dies (350°C+) to handle high-cure temperatures.
Wire enameling die compatibility with PAI is widely used for aerospace harnesses, it always requires ultra-hard dies (HV > 3000) to resist abrasive fillers.
Benefits of Wire Enameling Die:
- Ultra-smooth and uniformity enamel finish: The enameling die ensures a mirror-like surface finish by precisely controlling enamel flow dynamics, critical for high-frequency applications.
- Precise coating concentricity: Wire enameling die technology maintains concentricity within 0.3% tolerance through balanced pressure distribution, eliminating electrical weak spots.
- Long die life and wear resistance: Made with advanced materials such as PCD, the PCD enameling die offers outstanding wear resistance and a longer service life, minimizing downtime and replacement costs.
- Minimal enamel buildup and leakage: The optimized design of enameling dies for round conductors minimizes enamel accumulation and prevents leakage, ensuring clean, stable, and uninterrupted production.
- Compatible with all major enamel types: Our wire enamel wire die is engineered to handle a wide range of enamel types, including polyester, polyurethane, and polyimide without compromising performance or lifespan.
- Minimal variation in finished product diameter after enameling: Using a high-precision enameling drawing die allows for tight control over coating thickness, ensuring minimal variation in final wire diameter for high-spec applications.
- Cost efficiency: Juxin enameling die with superior durability and high precision, reducing material waste and maintenance frequency.

FAQs
What is enameling dies?
An enameling die is a precision tool used in the production of insulated magnet wires. Commonly made with durable materials like PCD, a PCD enameling die ensures uniform enamel coating and high wear resistance. These tools are essential for applying insulation to copper or aluminum wires, particularly when enameling dies for round wire applications.
How does wire enameling die work?
A wire enameling die works by guiding the bare wire through a calibrated aperture while it passes through a liquid enamel bath. The enamel drawing dies meters and wipes off excess enamel, ensuring a consistent coating thickness. Afterward, the wire enters a curing oven, where it produces a smooth and durable insulation layer. High-performance wire enamel wire die systems help maintain coating accuracy, reduce waste, and improve electrical performance.
