Win Big Automotive Client: Chengpin High-Precision Wireless Charger Induction Coils Beat Competitors

2026-07-20

Automotive-grade wireless charger induction coils are core precision components for in-car wireless charging systems, requiring ultra-stable resistance output, micron-level dimensional accuracy, and long-term operational reliability — with far stricter technical thresholds than ordinary consumer electronic coils. After six months of rigorous technical comparison, sample testing and supplier screening against multiple industry competitors, Chengpin Technology successfully secured a formal mass-production order for automotive wireless charging coils. We won the project by virtue of our exclusive precision manufacturing technology, customized R&D capabilities, and stable mass-production quality system.

Urgent Automotive Project Crisis: Multiple Suppliers Failed in Sampling Test

Six months ago, a professional automotive electronic manufacturer in Nanjing launched a core car wireless charger induction coil project with extremely stringent technical specifications and tight sampling deadlines. Facing urgent R&D and mass-production progress pressure, the client sampled and audited multiple professional coil suppliers, yet all peer manufacturers failed the performance test and could not deliver eligible products.

The key failure cause of all competitor samples was uncontrolled excessive coil resistance, which failed to meet standard automotive-grade tolerance requirements. As the official sampling deadline approached and no qualified supplier could be confirmed, the entire automotive wireless charging project faced suspension, bringing huge economic losses and project delays to the client.

Extreme Technical Difficulties of Automotive Wireless Charger Coils

Through one-on-one technical docking and parameter verification, our engineering team confirmed that this automotive induction coil adopted high-standard 0.08*105-strand ultra-fine hot-air bonding wire. The project involved two highly difficult technical challenges that most coil factories cannot overcome:

First, the coil terminal lead adopted an ultra-short design with an accurate length of only 4.6mm. Second, the ultra-fine multi-strand wire needed precise 90° angle bending molding. Traditional manual bending processes inevitably cause partial strand breakage, resulting in sharp resistance deviation and unqualified wireless charger induction coils. This technical bottleneck was the core reason why numerous manufacturers were eliminated in the client’s sampling stage.

Customized R&D Solves Industry Technical Bottlenecks Completely

To break through the industry technical bottleneck of automotive wireless charger coils, Chengpin Technology immediately organized a cross-department technical project meeting. We completely abandoned the unstable manual bending process and took the initiative to develop a custom pneumatic lead bending machine exclusively for ultra-fine multi-strand coil terminals.

This self-developed pneumatic precision equipment achieves fully automated control of bending strength, angle tolerance and dimensional consistency, fundamentally eliminating wire breakage and resistance deviation of ultra-fine strands. Our R&D team completed structural design and parameter confirmation in 3 days, finished equipment customization and debugging in a short cycle, and delivered fully compliant automotive-grade coil samples to the client within 2 days after equipment commissioning.

Full Qualified Sampling Officially Wins 50K Mass Production Order

The client conducted comprehensive professional testing on our delivered automotive wireless charging coils, covering inductance consistency, resistance stability, dimensional tolerance, and bending molding accuracy. All test data fully complied with strict automotive-grade standards with zero defects and zero deviations.

The client first launched a 1,000-piece trial production verification. With fully stable batch performance and zero quality failures, the client officially recognized our technical strength and quality control system, and immediately placed a 50,000-piece mass production order, establishing a long-term exclusive cooperative partnership for automotive wireless charging coil supporting.
