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
Motorneo provides a comprehensive range of leading processes for motor core laminations. Including compound stamping, single-tooth concentrated winding motor core, stacking motor lamination, stator injection molding, motor rotor stator filled with epoxy resin, and aluminum die-cast rotor.
Compound Stamping
Compound stamping utilizes a die and punches to press, cut, and form laminations from silicon steel sheets. This rapid production rate is cost-effective for medium and large-sized motor laminations for mass production.
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.
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.
bonding
Lamination stacks bonded together with Glue dot bonding technology and Self Bonding process.
Welding
Welding includes laser welding and TIG/MIG welding for precise, efficient bonding of laminations in electric motor cores.
Cleating
Cleating involves adding metal tabs or clips to the stator laminations, allowing them to be fastened together.
Riveting
Riveting involves using metal rivets to join the motor rotor and stator laminations together.
Aluminum Die-Cast Rotor
Motorneo 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
Motorneo offers stator injection molding insulation and motor lamination core epoxy powder coating insulation process. Both insulation technologies enhance motor longevity and efficiency making them ideal for automotive to renewable energy.
Injection Molding Stator
The injection molding stator process involves creating 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.

Wire EDM electrical discharge machining with wires (usually made of brass or copper) can cut conductive materials with extreme precision.
Both techniques empower us to create samples quickly and efficiently, and prototyping time is usually 5-15 days.
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.
Compound vs. progressive stamping, how much do you know? Compound die stamping requires the precise assembly of individual layers before stamping, while progressive die stamping involves feeding continuous strips of material through a continuous press to form laminations.
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.
