Our Advantages in Motor Stator & Rotor Stamping
Motor stators and rotors are the core components of electric motors, formed by laminating hundreds of thin silicon steel sheets. At Yixing Technology, we understand that precision is paramount. With over 20 years of experience, we provide not only high-performance progressive dies but also flexible mold manufacturing solutions tailored to your specific production needs.
1. High-Speed Precision Progressive Dies
For mass production, our progressive dies combine massive scale with microscopic precision:
Exceptional Accuracy
Feed tolerances of ±0.02mm and cutting edge tolerances of ±0.01mm, achieved through advanced wire EDM and grinding.
150M+ Stroke Mold Life
Critical punch pins use tungsten carbide engineered for over 150 million strokes. Ultra-precision guiding systems ensure decades of consistent performance.
Auto Lamination Riveting
Special riveting points automatically interlock each lamination, forming complete motor cores directly in the die—no secondary operations needed.
Max Material Utilization
Through optimized nesting design, we achieve up to 90% material efficiency to reduce waste and cost.
Zero-Burr Blanking
Precisely controlled mold clearance and mirror-finished carbide edges ensure clean, burr-free cuts every time.
Sustained Precision
Even at 300–1,500 SPM, our expertise in materials, heat treatment, and assembly ensures stable positioning without shift.
2. Flexible Molds for Rapid & Small-Quantity Manufacturing
We understand that traditional tooling can be expensive and time-consuming. That’s why we also offer flexible mold solutions for rapid prototyping and small-batch production:
WEDM-LS Precision Machining
We utilize high-precision WEDM-LS (Wire EDM Low Speed) to produce molds with tight tolerances required by motor stator and rotor applications, ensuring quality even at lower volumes.
Whether you need the high-speed efficiency of progressive dies or the flexibility of rapid mold manufacturing, our 20+ years of expertise ensure that every motor core meets the highest standards of performance and durability.
