Transformer Laminations
The EI laminations are a good choice for large transformer cores. Transformer core laminations typically are made of thin silicon steel due to their favorable magnetic properties.
Precision Motor Lamination Stamping
Our stamping division boasts a diverse range of high-speed and common punching machines in various models and tonnages, enabling swift customization to meet unique client requirements. We offer many motor lamination stamping ways.
Progressive Stamping is a manufacturing process that efficiently produces complete rotor and stator lamination without the need for secondary operations.
It is suitable for small size but large volume generators and motors lamination production.
yields high volumes of electric motor laminations and lamination segments within a short timeframe; the construction of dies may involve a longer timeline and higher costs.
Compound Stamping produces a complete motor lamination in one station and laminations have good flatness and concentricity.
While production rates of compound stamping are usually slower, the cost of tooling is less expensive and the lead times to build the tooling are quicker.
Compound stamping is efficient and economical for small-to-medium volume production.
Rotary Notching is a cost-effective choice for large motor lamination production.
Our CNC Rotary Notching press utilizes a Servo Driven Indexer, which can produce high-precision motor rotor and stator laminations.
The rotary notching process is suitable for low-to-medium volume stator rotor production and lamination prototyping. Our manufacturing lamination outer diameter of up to 1250mm.
Tooling Design And Manufacture
The stamping lamination tooling determines the quality of the lamination, we use advanced slow-moving wire-cutting equipment to manufacture the highest quality tool to meet your specific needs.

Motor Core Lamination Bonding Capabilities
As a premier electric motor core manufacturer, we specialize in lamination bonding techniques including glue dot bonding and self-adhesive bonding. This process eliminates interlaminar shorts common in traditional unitizing methods and enhances the efficient and performance construction of motor and transformer laminations.
Glue Dot Bonding
In the process of glue dot bonding for motor laminations, adhesive dots are strategically applied to the single motor lamination surfaces. Subsequently, the iron core lamination undergoes curing in an oven and is fused to hold the laminations together securely.
Self Bonding
In self-bonding motor lamination, a full-surface coating is applied externally to the electrical steel lamination, then oven-cured to achieve fusion, ensuring a robust and integrated bond for optimal motor performance.
Rotor And Stator Core
Lamination Stacking Assembly
Interlocking
In motor lamination, interlocking points are created during progressive stamping, enabling laminations to self-stack into cores.
Welding
We offer MIG, TIG, and laser welding to stack stator laminations. This solution can stack motor cores from loose laminations.
Shaft Inserting
The shaft insertion involves precision placement of the shaft into the rotor assembly. Suitable for small to medium-sized motors.
Riveting
Motor lamination riveting involves the use of rivets to fasten laminations to create robust motor iron cores.
Cleating
Stator laminations cleating stacking including straight or skew cleats. This stacking method ensures efficient assembly.
Bolt
Motor laminations are stacked together using blots, particularly for stators with larger outer diameters.
