Meta Description: Pingxiang Chengpin Tech delivers full custom transformers with 20-year R&D experience. 1:1 engineer support, full parameter adjustment, free prototype samples for global electronics buyers.
Finding a reliable transformer supplier that fully matches your circuit design is challenging for electronics OEMs. Most factories only offer standard parts with limited modification space. Chengpin Tech stands out with 20 years of dedicated high-frequency transformer R&D and customized manufacturing, serving new energy, industrial control, medical devices and consumer electronics industries with full one-stop OEM & ODM service.
We have accumulated mature winding solutions covering four major vertical markets:
- New energy: EV charging, energy storage power transformers
- Industrial equipment: PLC, sensor high-frequency isolation coils
- Medical electronics: Low-noise miniature medical transformers
- Consumer electronics: Wireless charging, smart home power coils Our R&D team fully understands industry-specific standards like medical insulation requirements and automotive IATF specifications, avoiding repeated design revisions for clients.
- Accept drawings, physical samples, BOM parameter requests for full development
- 100% restore your original design; adjust inductance, withstand voltage, size and pin layout on demand
- Pre-production design optimization & cost reduction consultation free of charge
- One-on-one dedicated R&D engineer full technical docking throughout the project Unlike trading companies without labs, our internal R&D center verifies all modified parameters before sampling to eliminate post-mass-production defects.
We provide free prototype samples for all custom projects, cutting your early-stage trial and error investment. Our dedicated small-batch prototype line finishes samples within 3 days, supporting rapid verification during product iteration cycles.
Client: European Medical Device OEM, 2026 Project Demand: Mini isolation transformer for portable blood testers Pain point: Previous suppliers could not adjust inductance accurately and failed medical insulation standards Chengpin Solution: Engineers optimized winding turns, adjusted withstand voltage to 1.5kV, fully restored client original circuit layout Result: Samples passed all medical reliability tests; mass order 800,000 units annually Client Quote: “Chengpin’s one-to-one technical support solved all our design adjustment troubles without extra sampling fees.”
