High-Performance Self-Bonding Enameled Wire Solutions

In the power industry, where higher efficiency, smaller size, and more reliable performance are constantly pursued, traditional coil manufacturing methods are facing bottlenecks. If you are designing next-generation high-efficiency motors, compact transformers, or precision sensors, Self-Bonding Enameled Wire is undoubtedly the key to achieving a technological leap forward. 

Flait Aluminum specializes in providing advanced magnet wire solutions for the power industry. Our self-bonding enameled wire products are designed to help engineers push the boundaries of innovation.

What is Self-Bonding Enameled Wire?

Self-Bonding Enameled Wire is an advanced type of magnet wire that features an additional layer of special thermoplastic or thermosetting bonding agent coated over the standard enamel insulation. It requires no additional adhesives, tapes, or lashing. When heated to a specific temperature (e.g., via an oven or the heat generated by the coil itself during energization), this coating softens and flows, forming a strong, uniform, and insulated permanent bond between the individual turns of the wire and between layers within the coil. After cooling, the coil becomes a solid, single unit.

Core Advantages and Specifications of Flait Self-Bonding Enameled Wire

• Core Advantages

✅ Exceptional Bonding Strength: Forms a robust coil structure that effectively resists the immense electromagnetic forces, vibration, and shock generated by motors and transformers during high-speed operation, frequent starts/stops, or in harsh environments. Prevents inter-turn loosening and wear, significantly enhancing product reliability and lifespan.

✅ Achieves Ultra-High Space Utilization: Eliminates the need for traditional materials like slot wedges, lashing cords, and separator strips, allowing for a higher slot fill ratio in your coil design. This means you can embed more copper conductors in the same volume, increasing power density, or create smaller, lighter end products.

✅ Simplifies Production Process and Reduces Costs: The coil forming and curing process is simple and fast, making it highly suitable for automated mass production. It eliminates multiple production steps (such as lashing and impregnation varnish drying), significantly reducing production time, labor costs, and material costs (saving on insulating varnish and lashing materials).

✅ Excellent Overall Performance: Our products offer various thermal classes (e.g., Class 155 to Class 200), ensuring stable performance even in high-temperature environments. Simultaneously, the insulation layer possesses good chemical resistance, dielectric strength, and flexibility.

• Technical Specifications & Data

✅ Temperature Class: Comprehensive coverage of high thermal classes including 155 (Class C), 180 (Class H), 200 (Class N), and even 220 (Class R), meeting various application needs from general appliances to high-temperature and harsh environments.

✅ Size Specifications:

  🔹Round Wire: Offers a wide range of conductor diameters, from a fine 0.2mm to 2.0mm (approx. AWG 32 to AWG 12), meeting the design requirements for various current ratings.

  🔹Rectangular Wire: Can provide self-bonding wire with rectangular cross-sections based on customer needs, achieving higher space utilization and heat dissipation efficiency.

✅ Bonding Conditions: The typical bonding/curing temperature range is usually between 130°C – 180°C, with a heating time of approximately 15 – 60 minutes (specific parameters depend on wire gauge and coating type). The process is straightforward and easy to integrate into existing production processes.
