Breaking Industry Bending Challenges! Fuying Electronics Passes Toyota Certification for Automotive-Grade Precision Coils

Automotive-grade on-board wireless charging coils are high-precision and high-reliability core components. They require high temperature resistance, vibration resistance, cold and heat impact resistance, and bending integrity, with far stricter standards than consumer electronic coils. With nearly 20 years of professional experience, Dongguan Fuying Electronics specializes in high-difficulty custom automotive coils. We have successfully passed Toyota certification and entered its high-end automotive supply chain for mass production.

Our Japanese client supports Toyota’s on-board charging equipment. The project required multi-strand ultra-fine enameled wire coils with precise 90° hard bending, zero wire damage and stable resistance. All products must pass strict automotive tests including -40℃~125℃ temperature cycling, high-frequency vibration and long-term aging tests. Many suppliers failed the durability test and could not meet the standards.

Multi-strand ultra-fine wires are fragile and easy to break during conventional winding and bending, resulting in unstable resistance and product failure. The client’s project was severely delayed due to unqualified samples from mainstream manufacturers.

Fuying Electronics set up a dedicated automotive R&D team, developed exclusive pneumatic bending equipment, and optimized winding, bending and shaping processes. We completed process debugging in 3 days and delivered qualified samples in 2 days, greatly shortening the client’s R&D cycle.

All samples passed Toyota’s full authoritative tests with stable performance under extreme working conditions. We successfully obtained Toyota system certification and a 50,000-unit mass production order.

This project proves Fuying Electronics’ strong capability in automotive-grade precision coil customization. We now support stable mass production with strict quality control, providing reliable custom coil solutions for global automotive electronic scenarios.
