Our compound Stamping Capabilities For Motor lamination stacks

We are proud to have strong motor core lamination stamping capabilities. Our advanced stamping technology allows us to produce high-accuracy, precision lamination stacks in various motor applications.

Composite stamping is suitable for medium motor laminating. Therefore, the mold size is relatively large, and the entire mold is fixed between the piston and the press base. The disc is instantly stamped into a stack, and the whole process of feeding and unloading can be operated by an automated system or manually. It runs much faster than rotary slotting.

stamping motor core lamination

We offer a wide range of stator and rotor lamination stacks sizes. Our stamping process utilizes advanced technologies to ensure a consistent product. This ensures that each part is precise and uniform in size, shape, and thickness.

In addition to our compound stamping capabilities, we also offer annealing, grinding, assembly, and progressive stamping services to ensure that we can provide a complete motor lamination stack manufacturing solution.

After compositing the laminated sheets, we stack them in the die by gluing, welding, and riveting to form the core components.

In conclusion, we offer custom designs to fit your application requirements. Whether you need a prototype lamination or high-volume production, we can help you design the perfect stamping tooling for your needs. 

materials used in stator and rotor lamination

We have years of experience providing our customers with the best materials for this type of stamping. Our selection includes a variety of options to accommodate different requirements when it comes to motor lamination stack compound stamping.
Silicon steel is a common material used for motor core lamination compound stamping. These steel alloys are usually made from iron and steel and are corrosion-resistant and magnetic, which makes them suitable for this task.

We also provide other materials for stator and rotor lamination, such as:

Silicon steel

Nickel alloys

Cobalt alloys

Thin-gauge electrical steel

Grain Oriented steel

Non-Grain Oriented Steel

Cold Rolled Motor Lamination Steel

Comprehensive Testing Services

quality control

We have a strict inspection process to ensure the quality of motor lamination stacks.

First, we use quality materials when manufacturing their motor laminations, which will help guarantee that they remain effective and reliable over time.

Second, we accurately measure and monitor each part of the process.

This means taking precise measurements before, during, and after lamination to ensure that all components have been cut properly and adhere to set specifications.

Our testing equipment includes the projector, CMMs, a tension meter, a vernier caliper, and so on.

Finally, we also inspect their completed motors thoroughly before shipping them out.

Secondary Operations


We can stack the laminations into a motor core in various ways, such as rivet, glue, and welding. Stacking them correctly ensures that the motor core won’t fail during operation. When the stator stack length is too large, interlocking and welding can be used simultaneously. The method used to stack the laminations must be chosen based on factors like power requirements and availability of materials.


Riveting is one way of stacking laminations for a motor core. This technique involves using small metal pins to hold the parts together, which makes it a reliable option for applications with high power demands.


Glue is also an effective way of stacking lamination for smaller motors because it provides good adhesion between parts and creates an airtight seal between them.


It combines multiple silicon steel laminations with welds to form components used in electrical motors, generators, and alternators. There are two types of welding stacking used for stator laminations: laser welding and TIG welding.

Motor lamination compound stamping FAQs

Motor lamination compound stamping is a process used to manufacture electric motors.

It involves using a die and punch to press, cut, and form laminations from cold-rolled steel, which are then stacked to form an electric motor’s stator or rotor core.

The thickness of stator compound stamping typically ranges from 0.5mm to 1mm, depending on the specific application and requirements of the motor core lamination.

This thickness is important as it ensures that the motor core is insulated and protected from electrical damage.

If you’re unsure which thickness is ideal for your motor lamination project, then it’s best to consult us. We can advise you on the right thickness for maximum safety and performance.

Creating these cores can range from simple single-stamping operations to complex compound die systems with multiple stages and operations.

To begin this process, flat steel strips are fed into one end of the machine, punched, and formed into individual laminations with teeth on two sides.

Once this step has been completed, the punched parts can be either stamped again on both sides or combined with other components, such as bearings or shafts, before being pressed together in a stack to create an assembled stator or rotor core.

Motor lamination compound stamping is an efficient and cost-effective production method for motor cores.

Compared to traditional lamination techniques, this process helps reduce the risk of surface defects, such as scratches.

It also results in lamination stacks that are more precise and consistent, which helps to improve the overall performance of the motors.
