Capabilities For Compound Stamping Die Design And Manufacturing
Our company boasts compound stamping die design and manufacturing capabilities, incorporating advanced techniques such as wire EDM (Electrical Discharge Machining) and grinding. Our skilled engineers and designers utilize state-of-the-art CAD/CAM software to design and create intricate compound dies.
With wire EDM, we can precisely cut complex shapes and contours into the die, ensuring the utmost accuracy and consistency in each lamination produced. Furthermore, our grinding capabilities allow us to fine-tune the die surface, optimizing its performance and longevity.
The manufacturing cost of compound die is relatively high, so our stamping tooling service department records all Settings and the number of mold trips daily. Through these data, you can determine the current use of the mold. Our customers provide free maintenance services during the everyday life of the mold.
Our Leading Processes For Motor Core Laminations
We have innovation, and excellence converges to provide a comprehensive range of leading processes for motor core laminations. As a trusted China manufacturer, we can provide progressive techniques that cater to diverse industry needs. Our cutting-edge solutions include compound stamping, single-tooth concentrated winding motor core, stacking motor lamination, injection molding stator, stator filled with epoxy resin, and aluminum die-cast rotor.
Compound Stamping is a highly efficient and economical lamination stamping manufacturing process. This stamping process involves assembling multiple layers of different materials to a complete motor lamination in one action. Our motor lamination stamping used high-grade electrical steel with specific silicon content.
Stamping services are well-suited for automated feeding and output systems cooperation. The synchronization action between our press machine and automation systems reduces downtime, minimizes human intervention, and improves overall efficiency.
Compared to progressive stamping and rotary notching, compound stamping resulting in motor laminations boasts excellent flatness and concentricity. Our compound stamping is suitable for medium and large production. Due to its rapid production rate, it is a cost-effective choice.
Single Tooth Concentrated Winding Motor Core
Our Single-Tooth Concentrated Winding Motor Core, unlike traditional laminated cores, innovative design consolidates the magnetic flux path into a single tooth, minimizing energy losses and enhancing overall motor efficiency.
The Single Tooth Concentrated Motor Core is characterized by its streamlined structure, optimized magnetic circuit, and reduced cogging effect, resulting in smoother operation and improved control.
This breakthrough technology offers significant benefits across various applications, from industrial machinery to electric vehicles, where precision and energy conservation are paramount.
Compound stamping Laminations Stacking Process
Stator and Rotor lamination stacking are crucial in manufacturing iron laminated cores, where individual lamination stacking forms a complete motor core. We can be employed in various methods for stacking, such as welding, cleating, riveting, and bonding.
Cleating involves adding metal tabs or clips to the stator laminations, allowing them to be fastened together.
Riveting involves using metal rivets to join the motor rotor and stator laminations together.
Aluminum Die-Cast Rotor
Aluminum die-cast rotor lamination is a critical component of electric motors, renowned for its lightweight and excellent thermal conductivity properties.
In our manufacturing process, molten aluminum is injected into a high-pressure mold, precisely shaped to create the rotor’s intricate design. Once the aluminum solidifies, our mold is opened, revealing a robust and precisely formed rotor.
The die-cast rotor’s lightweight nature reduces the motor’s overall weight. Moreover, aluminum’s exceptional thermal conductivity ensures efficient heat dissipation, contributing to the motor’s longevity and reliability.
We can manufacture cast various sizes of aluminum rotor iron core and a largest outer diameter of up to 1250mm. We also can deliver aluminum cage rotors that meet the highest industry standards.
Stator injection molding and insulation
Our company specializes in providing innovative solutions for stators. From custom designs to reliable and consistent production, our motor stator core injection molding and insulation services are tailored to meet the unique needs of various industries, ranging from automotive to renewable energy.
Injection Molding Stator
Injection molding stator is a manufacturing process used to produce stators for electric motors. We create a mold with cavities in the stator shape, and a molten material, typically a thermosetting or thermoplastic polymer, into the mold under high pressure.
Once the material cools and solidifies, our mold is opened, and the completed stator with intricate winding slots and precise geometry is removed.
Stator Filled With Epoxy Resin
We can provide stators filled with epoxy resin to enhance electric motor stators’ performance and durability. The stator windings and coils use epoxy resin to impregnate and encapsulate, which hardens into a solid, protective material.
Our epoxy resin creates a seamless and robust barrier around the windings, ensuring motor operation, even in demanding conditions.
Our Quality Control For Compound Die Stamping Motor Cores
We have achieved ISO/FDIS09001:2008 and ISO/TS16949 certifications, highlighting our commitment to quality management. We use advanced inspection tools for comprehensive quality control, such as CMM (Coordinate Measuring Machine) Inspection and Projector Detector.
With CMM Inspection, we can accurately measure and validate compound die stamping motor laminations’ dimensional accuracy and tolerances, ensuring they meet precise specifications. The Projector Detector allows us to conduct thorough visual inspections, detecting any surface imperfections or irregularities that may affect performance.
Through these stringent quality control practices, we guarantee that our electric motor laminations are flawless, efficient, and compliant with industry standards.
Materials Used In Stamping Manufacturing Process
There are many kinds of motor lamination steel-grade materials. Usually, our compound stamping manufacturing process material selection for high-quality electrical steel(silicon or lamination steel) is 0.10 to 1 mm thick. Electrical steel has two kinds of oriented and non-oriented steel; in most cases, we use unoriented steel. This high-grade steel contains silicon, which reduces eddy current losses, a critical factor in improving motor efficiency.
Custom Electric Motor Stator Rotor Cores
Customized compound die-stamping motor stators and rotor cores find various applications across various industries. Thanks to their versatility and adaptability, they commonly apply in electric vehicles (EVs) and hybrid electric vehicles (HEVs), industrial pumps, compressors, Vent plates, the renewable energy sector(Wind/Fire Power generators and solar energy systems), etc.

Compound Stamping Motor Core Laminations FAQs
Lead times can vary based on specific requirements and order volumes, but compound stamping generally allows for efficient production and shorter lead times.
Compound stamping offers various advantages, including improved motor efficiency, higher power density, reduced noise, and vibration, enhanced thermal performance, and cost-effectiveness for medium-to-large volume production.
You can start your search by conducting online research, exploring industry directories, attending trade shows, or seeking recommendations from industry professionals.
The primary difference between compound stamping and rotary notching is their purpose and scope. Compound stamping presses create complex shapes with multiple features on a single sheet, making them suitable for intricate parts. On the other hand, rotary notching is specialized for creating precise slots in motor laminations, enhancing motor efficiency and performance.
