We focus on the customization and production of custom inductor coil, micro precision coil and air-core coil, providing reliable OEM and ODM solutions for global customers. With years of experience in producing medical grade inductor coil and customized hearing aid coil products, we have grown into a trustworthy precision inductor coil supplier serving the global medical wearable device industry.

We recently delivered a successful customization project of high-precision air-core coil for a well-known European medical brand. The client needed exclusive custom coil for medical wearable devices used in mini hearing aids, featuring an ultra-fine 0.19mm inner diameter, consistent inductance value, low power loss and excellent anti-interference performance. Many manufacturers failed to achieve stable mass production for this ultra-precision product. As a professional 0.19mm ultra-fine precision coil supplier, we tailored professional solutions that fully meet strict medical industry standards.

Our professional R&D team optimized the winding structure and production process for this batch of custom micro air core coil for hearing aid. We completed precision mold development and sample verification within 3 days, effectively solving common problems such as coil deformation and parameter deviation. As a qualified high precision medical inductor coil manufacturer with complete ISO certifications, we adopted full-process quality inspection standards. We successfully delivered 50,000 pieces of stable inductance micro coil for medical devices in 15 working days, providing one-stop OEM medical wearable coil customization services with zero defective products.

This project perfectly proves our professional strength in precision coil customization. Golden Eagle Coil always provides stable, high-precision and cost-effective coil products for medical devices, automotive electronics, consumer electronics and IoT industries, winning long-term recognition from global customers.
