Mold Overview
The motor stamping die is a laminated mold for producing motor iron cores. It has multiple mold cavities with different functions for cutting, punching, bending, etc. Continuous production is achieved through high-speed automatic stamping stacking iron sheets together to form the motor iron core.
There is a hollow channel at the bottom of the mold. When the iron core of the motor reaches the specified height, the iron core will automatically fall out of this channel, and the entire production process does not require workers’ participation. The iron core stamping mold automatically completes all the work.

Motor stamping die advantage
- Fully automated production
Motor stamping molds and high-speed stamping machines can achieve fully automated production, improving production efficiency and reducing manufacturing costs.
- Long service life
The key components of this motor stamping mold are made of hard materials. They are treated with advanced vacuum quenching and tempering.
So the mold has a long service life and can withstand long-term, large-scale stamping operations.
- No additional maintenance required
The motor stamping die does not require high maintenance costs during use. Only a small amount of lubricating oil must be added to the guide column every month. It must be covered with a dust-proof cloth if it is not used for a long time.
- Low wear
Due to the very reasonable structural design of the mold, high-precision CNC machine tools process all parts, and all parts have undergone scientific and precise fit clearance. Its wear during use is relatively small and can maintain good precision output for a long time.
Motor stamping die main features
This mold has multiple layout methods, and its main feature is to achieve faster production efficiency. For example, the rotor and stator can produce two sizes of iron cores in the same mold, which not only greatly improves efficiency, saves raw materials, but also reduces costs.
A new type of iron core with a rotating design for the coil channel has higher requirements for stamping dies. The iron sheets need to rotate accurately during the stacking process; therefore, it is necessary to have servo motors at key positions of the mold to control the rotation angle and solve this problem accurately.
The shape of the rotor is usually circular. To save materials, the motor stamping die has two or more cavities arranged scientifically, which can save more than 20% of raw materials. For large-scale production factories, the annual cost savings are very objective.
