Motor stators and rotors are the key parts of electric motors, formed by laminating hundreds of thin silicon steel sheets. At Yixing Technology, we understand that precision is paramount. With 20+ years of experience, we provide not only high-performance progressive dies but also flexible Mold Manufacturing to meet 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.

· 150 million strokes mold life – Critical punch pins use tungsten carbide, engineered for over 150 million strokes. Ultra-precision guiding systems ensure decades of consistent performance.

·  Automatic Lamination Riveting – Special riveting points automatically interlock each new lamination with the previous one, forming complete motor cores directly in the die. No secondary operations needed.

·  Maximum Material Utilization – By reasonable design, we can achieve 90% material efficiency.

·  Zero-Burr Blanking – Precisely controlled mold clearance and mirror-finished carbide edges.

    Sustained Precision –even the mold runs at 300–1,500 strokes per minute, our expertise in materials, heat treatment, and assembly ensures the position is stable and does not shift.

    We know that traditional tooling can be expensive and time-consuming. We also provide more flexible molds for Rapid & small quantity Manufacturing solutions.

·   WEDM-LS to ensure mold‘s precision: We utilize high-precision WEDM-LS to produce the mold. This allows us to produce tight tolerances, which are needed by the Motor Stator and Rotor

    Whether you need the high-speed efficiency of Progressive Dies or the flexibility of Mold Manufacturing, our 20+ years of expertise ensure that every motor core meets the highest standards of performance and durability.
