Product Description


We are one of the pioneers in producing micro thin enameled wires below 0.03mm in China. Our R & D team has 20 years of market experience.We have achieved the goal of "zero pinholes after stretching" for ten years. In 2019, our finest diameter is 0.011mm, and mass production has been achieved.When the displays return the transformer industry, we are the No.1 Chinese brand with a share of cake.We rival the internationally renowned enameled wire brands for production, technology, raw materials.We surpass them in terms of "service, quick response"; 30% lower "price" is our advantage.


We have a long history of producing self-adhesive lines. Since the beginning of our factory, we have started to develop and produce self-adhesive lines. Because of our strong R & D strength, our products have a wide range of applications.We have a full range of self-adhesive lines and a wide range of applications.Thermal class is155C, 180 C, 200 C, 220 C. Conductor material includes enameled round wire, enameled copper-clad aluminum wire



Speaker coil, such as microphone, earphone, speaker, hearing aid,Bluetooth audio, speakers, etc.;High-temperature voice coils, such as car audio, home theater, high-power speakers, etc. High-sensitivity voice coils, such as headphone speakers and high-temperature-resistant voice coils;micro vibration motor,such as focus-driving,(coin-type, coreless-type) and other electrical and electronics components, such as inductor, watch coil, coin machine coil, buzzer;magnetic head, IC card.


  • Excellent adhesion and ductility;

  • Excellent conductivity, electrical properties;

  • Good performance at high heat resistance, heat shock and cut through.
