Large-Diameter Stamping
Our high-tonnage press lines and large-format progressive dies easily handle the massive outer diameters (OD) typical in heavy industrial pump and blower motors.
INDUSTRIAL MOTOR SOLUTIONS
HEAVY-DUTY MOTOR CORE STAMPING FOR INDUSTRIAL AUTOMATION & MACHINERY
Powering the backbone of global industry. We provide high-volume, precision stamping for industrial AC/DC motors, heavy-duty pumps, fans, and conveyor systems. Engineered to meet strict IE4 and IE5 super-premium efficiency standards, our carbide progressive dies and lamination mass production ensure minimal core loss, robust structural integrity, and cost-effective scalability for global motor manufacturers.
THE EFFICIENCY MANDATE
MEETING GLOBAL IE4 & IE5 EFFICIENCY STANDARDS WITH PRECISION STAMPING
Industrial motors consume the majority of global electrical power. With governments enforcing strict IE4 and IE5 efficiency regulations, manufacturers must drastically reduce hysteresis and eddy current losses. Inferior stamping causes edge stress and burrs that degrade magnetic flux. By utilizing sub-micron optical-ground tooling, we guarantee razor-clean edges and perfect concentricity. This minimizes airgap variations and optimizes electromagnetic performance, helping your standard industrial motors achieve super-premium efficiency effortlessly.
ROBUST MANUFACTURING
ADVANCED STAMPING CAPABILITIES FOR HEAVY-DUTY MOTORS
Industrial environments demand indestructible reliability. Explore how our heavy-duty stamping and core consolidation technologies ensure your motors survive decades of continuous operation.
INDUSTRIAL-GRADE MATERIALS
HEAVY-GAUGE ELECTRICAL STEEL FOR DURABILITY AND COST-EFFICIENCY
Balancing performance with raw material costs is the key to scaling industrial motor production. We source high-grade 0.50mm and 0.65mm Cold Rolled Non-Oriented (CRNGO) silicon steel directly from Baosteel and WISCO. These materials offer the perfect balance of excellent magnetic flux density and immense mechanical strength required for industrial machinery.

FREQUENTLY ASKED QUESTIONS ABOUT EV MOTOR CORES
Have technical questions about upgrading to IE5 efficiency, handling large stator dimensions, or heavy-duty core welding? Review our FAQs below or contact our industrial engineers to discuss your project.
How does your stamping process help us upgrade from IE3 to IE4/IE5 motor efficiency?
Achieving IE4/IE5 requires minimizing airgap variations and core losses. We assist by optical-grinding our die punches to sub-micron tolerances, ensuring <0.01mm burr and mathematically perfect stator/rotor concentricity. This maximizes magnetic flux efficiency without forcing you to buy drastically more expensive electrical steel.
What is the most cost-effective silicon steel thickness for general industrial AC motors?
For standard industrial induction motors (like pumps and fans) operating at 50/60Hz, 0.50mm CRNGO is the global industry standard. It offers the best balance between stamping productivity, material cost, and acceptable core loss.
Our industrial motors experience severe vibration. How do you prevent core delamination?
For heavy-duty applications, standard interlocking is often not enough. We provide automated secondary operations, including TIG welding, laser welding, and riveting across the outer diameter of the stator stack. This transforms the laminations into a single, indestructible solid block.
Can you design compound dies instead of progressive dies for our very large industrial motors?
Absolutely. For industrial stators with very large outer diameters (e.g., >300mm), progressive dies can waste too much material. We design high-precision single-hit compound dies that stamp the inner and outer diameters simultaneously, ensuring 100% concentricity while drastically reducing your material scrap rate.
