Technology Introduction
1. Winding technology development
Winding technology Development
Since 1989, we have pioneered and refined motor winding technology to keep pace with evolving market demands. Our journey began with core solutions for brush motor rotor winding, serving traditional automotive and industrial applications.
Over decades of innovation, we expanded our expertise to support a broader range of advanced motor types, including:
BLDC Stator Winding: Delivering precise, high-efficiency winding for brushless DC motors, widely used in home appliances, power tools, and new energy applications.
Hybrid Motor Winding: Developing flexible solutions for hybrid powertrain motors, balancing performance, reliability, and cost-effectiveness.
EV Motor Rotor Winding: Providing high-volume, consistent winding processes for electric vehicle traction motors, meeting the strict requirements of the global automotive industry.
Building on our foundational winding capabilities, we continuously optimize processes, tooling, and automation to ensure stable quality, improved efficiency, and full adaptability to custom motor designs.
Hairpin Technology Development
In 2002, we began our exploration of hairpin technology, starting with applications for starter motor rotors. As the global shift toward electrification accelerated, we evolved our solutions to meet the high-performance demands of electric vehicle (EV) motors.
Today, our mature EV Motor Pin Forming Technology covers the full process chain of flat wire motor manufacturing, including precision forming, twisting, welding, and insulation. We support diverse hairpin topologies, from basic U-pin designs to advanced multi-turn and segmented configurations, enabling our customers to achieve higher power density, lower resistance, and improved thermal performance in their EV motors.
This continuous evolution, from conventional winding to cutting-edge hairpin solutions, reflects our commitment to driving innovation in motor manufacturing technology.
2. Assembly technology development

Our full-stack self-developed hairpin flat wire technology covers the entire manufacturing process of hairpin stator production. From the initial paper insertion and all pin forming, through basket assembly, insertion, widening, twisting, and cutting, to the final stages of laser welding, insulation, and coating, every core process and key equipment is independently developed and mastered in-house. This full-process capability ensures high precision, stable quality, and flexible customization, enabling us to deliver efficient, reliable production lines tailored to diverse EV motor requirements.
5. Hairpin stator technology development
Our hairpin pin forming technology has evolved through multiple generations, delivering continuous breakthroughs in cycle speed and process capability.
From Gen 1 in 2017 (3.5s/pin) to Gen 4 launched in May 2025 (0.8s/pin), each iteration has significantly reduced forming cycle times, while evolving from basic punch forming to advanced 3D and U-forming processes. The latest Gen 4 sets a new benchmark in speed, enabling higher-volume, more flexible hairpin stator production to meet the growing demands of the EV industry.
